Older people's experiences of everyday travel in the urban environment: a thematic synthesis of qualitative studies in the United Kingdom

Abstract Compared to younger age groups, older people spend more time in their locality and rely more heavily on its pedestrian and public transport infrastructure. Qualitative studies provide unique insight into people's experiences. We conducted a qualitative evidence synthesis of United Kingdom-based studies of older people's experiences of travelling in the urban environment. We searched health, social science, age-related and transport-related databases from 1998 to 2017. Fourteen papers (from 12 studies) were included in a thematic synthesis, a three-staged process that moves iteratively between codes, descriptive themes and cross-cutting analytical themes. Emerging themes were discussed with policy advisers. Four overarching themes were identified. The first and second theme pointed to the importance of ‘getting out’ and of being independent travellers. The third and fourth themes highlighted how local environments and travel systems enabled (or prevented) older people from realising these valued dimensions of travel. The loss of local amenities and micro-environmental features, such as pavement quality, personal safety and aesthetic appearance, were recurrent concerns. Free modes of travel like walking and bus travel were highly valued, including the social engagement they facilitated. Our review suggests that, while its extrinsic value (reaching destinations) matters, the intrinsic value of travel matters too. The process of travel is experienced and enjoyed for its own sake, with older people describing its contribution to their wellbeing.


Introduction
The global population is ageing (Rechel et al., 2013;World Health Organization (WHO) 2015) and increasingly urban (United Nations Department of Economic and Social Affairs, 2014), trends led by early industrialising countries like the United Kingdom (UK). In the UK, 24 per cent of the population is aged 60 and destination' (Department for Transport, 2017a). Personal travel is therefore cast as an instrumental activity; a trip is 'a course of travel with a single main purpose' (Department for Transport, 2017a) such as going shopping or accessing services (e.g. medical consultations, entertainment, sports facilities). This understanding of travel frames much of the debate about transport exclusion and disadvantage (Pereira et al., 2017) and underpinned the introduction of the UK's concessionary bus scheme. By providing free bus travel for older people during off-peak times, the scheme seeks to provide 'a lifeline to facilities both within and outside their local area' (Department for Transport, 2012), particularly for those on low incomes (Butcher and Rutherford, 2015). The concessionary scheme operates via a swipecard bus pass (in London called a Freedom Pass) which enables older people to travel without charge during permitted periods.
While defining travel in terms of its extrinsic value underlines its essential contribution to wellbeing, it can overlook and obscure the experience of travel for its own sake (i.e. not undertaken primarily or solely to reach a destination). The concept of 'discretionary travel' has been used to describe such travel (Musselwhite, 2017b); however, it is more widely used to describe journeys that, in contrast to work journeys and trips to access everyday necessities, are regarded as non-essential (e.g. visiting friends and family). As Parkhurst et al. (2014: 129) note, by categorising such trips as discretionary, the concept 'risks marginalising the travel aspirations and needs of older people' for whom social visitsor simply being out and aboutmay be the main purpose of the trip.
Qualitative studies are uniquely equipped to uncover people's aspirations and experiences. They use methods and modes of analysis grounded in people's accounts of their everyday lives. Providing access to 'experts by experience' (NHS England, 2017), qualitative studies are increasingly valued by policy makers (WHO, 2016), with qualitative reviews and syntheses recognised to be an integral part of the evidence base for policy (Langlois et al., 2018).
There are a number of relevant reviews that include qualitative studies, including ones of walking, physical activity and healthy ageing (Annear et al., 2012;Barnett et al., 2012;Moran et al., 2014;Dadpour et al., 2016). However, none has a focus on older people's experiences of travel in the urban environment. Our review provides this focus. Mindful of national differences in urban form, transport infrastructures and travel patterns, our review focuses on the UK.

Aim
The aim of our review is to identify, assess and synthesise evidence from qualitative studies of older people's experiences of everyday travel in the urban environment in the UK.

Searching
We searched health, social science, and age-and transport-related databases for studies in English-language journals published between 1998 and 2017: MEDLINE, CINAHL Plus, Scopus and TRID (Transport Research International Documentation) and AgeINFO. Search terms included a combination of key words related to qualitative research methods, travel and the local environment. The searches were supplemented with hand searches of key journals (Journal of Planning Literature, Built Environment and the Journal of Transport and Health); we also checked references in earlier systematic reviews (Annear et al., 2012;Barnett et al., 2012;Moran et al., 2014;Dadpour et al., 2016). Additionally, we asked leading researchers in the fields of older people and transport to check the identified studies for completeness.

Screening
Records were screened by title and abstract to identify UK studies published in peer-reviewed journals. The full texts of journal papers were retrieved and screened by two reviewers (KF and HG) to determine eligibility for inclusion. Any discrepancies were discussed and agreed by consensus.
Eligible studies (a) included people aged ⩾60 resident in urban/suburban areas of the UK and (b) used a qualitative research design to gather older people's experiences of everyday travel in the urban environment. We included mixed-method studies where the qualitative component was reported separately, baseline data from intervention studies, and studies including both older people and stakeholders if the experiences of older people were separately reported.
We excluded studies where (a) participants were recruited based on their health condition (e.g. studies of people with diabetes); (b) the experiences of older people were not separately reported (e.g. studies of adults); and (c) rural participants were included and the experiences of older people in urban/suburban areas were not separately reported. We contacted study authors where the residential location of participants was unclear.
Data extraction and quality appraisal Data extraction was undertaken by one reviewer (SdB) and checked by another (HG) using a standardised form covering aims, study details, study design, analytical methods and key results. We assessed the quality of the reporting of the study using a standard framework which covers a range of domains, including methods, data analysis and ethics, with a maximum possible score of 36 (Hawker et al., 2002). Appraisal was undertaken by one reviewer (SdB) and checked by another (KF). The domains were not weighted and there was no a priori quality threshold for excluding papers; assessment was undertaken to ensure transparency (Carroll et al., 2012;Noyes et al., 2018).

Synthesis
We used thematic synthesis (Thomas and Harden, 2008), an approach that mirrors thematic analysis used in primary studies. The main difference is that the data include authors' interpretations as well as participants' accounts.
Thematic synthesis is a three-stage process that moves iteratively between coding, to the identification of descriptive themes, to the generation of cross-cutting analytical themes (Thomas and Harden, 2008;Booth et al., 2016). The first stage involved line-by-line coding of participant accounts and author interpretations by one reviewer (SdB) using NVivo version 11 (QSR, 2012). Coding was inductive, with the set of codes expanded as additional studies were added (Thomas and Harden, 2008). At least one code was given to all statements relating to travel and/or the local environment; statements often had multiple codes. The preliminary codes were discussed and refined by the review team (SdB, KF, HG). The final set comprised 151 codes, all of which related to older people's views and experiences; example codes included 'bus travel gives a sense of belonging to society' and 'unwilling to rely on social network for help'.
For the second stage, groups of related codes were identified, and combined into broader descriptive themes by the review team (SdB, KF, HG). The process involved repeated reference back to the papers from which they were derived, to ensure coherence and their grounding in the views and experiences of study participants. The descriptive themes related to older people's experiences of different travel modes (e.g. bus, car) and their local environment, as well as to individual-level factors (self-identity, health and personal circumstances, in particular).
The third stage of our synthesis involved identifying and mapping links between the descriptive themes (travel modes, local environment, individual-level factors) to generate analytical themes that, together, made sense of older people's experiences of everyday travel. Themes were discussed and refined with the project's policy advisers. The group included senior local government and National Health Service staff tasked with developing and/or delivering health, transport and environmental policies and services in their local urban areas, together with the lead for transport and health for older people at a major UK charity.
The review was guided by the ENTREQ ('Enhancing transparency in reporting the synthesis of qualitative research') statement (Tong et al., 2012).

General study characteristics
We identified 493 records. After screening (see Figure 1), 14 papers (reporting on 12 empirical studies) met the review inclusion criteria. Table 1 summarises the papers, including their aim/research question, participant details, sample size, location, methods and quality score. The majority (11) were published since 2010. Quality scores ranged from 20 to 30; only three papers had scores below the mean score of 25. Lower-scoring papers provided less information on ethics and methods (e.g. data collection, sampling strategy, data analysis and bias). Papers were based on studies undertaken in major cities and other urban areas in England, Scotland and Wales; there were no studies in Northern Ireland. Three included both urban and rural settings but enabled identification of findings relating to urban participants.
The studies included participants with a broad range of levels of mobility. Two (Guell et al., 2016;Zandieh et al., 2016) noted that participants with mobility limitations (e.g. not able to walk) were excluded and two noted that participants in sheltered accommodation and residential care homes were included. While not directly stated in the majority of studies, it is clear that the majority of participants were living in their own homes.  belonging to the city and to a 'community'. However, informal entitlements to particular spaces on the bus reflected less-valued social attributes such as need or frailty. Travelling by bus entailed the negotiation of social differences and personal vulnerabilities, and this carried with it potential threats to wellbeing.

All White British; range of socio-economic backgrounds although 'women aged over 80 living in less-deprived areas were over-represented'; in terms of 'physical functioning' 80% were 'third age', 20% 'fourth age'.
A QGIS approach using GPS devices and indepth individual interview.
Physical activity was measured using accelerometry/GPS device over a week and discussed in the interview.
The concept of neighbourhood changed seasonally and over the lifecourse, and was associated with social factors such as friends, family or community activities, rather than places. Spaces stretched further than the local, which is problematic for older people who rely on variable public transport provision. Exploring the importance of discretionary mobility in later life. Working with Older People 60 participants, aged 63-90 years, from an urban city centre, urban market town and two semi-urban areas.
Socio-demographic information was not reported; participants scored their health 7 on average on a scale of 1-10; 32 co-habited, 22 lived alone, 4 with family, 2 in a residential home.
Interviews asked participants to consider their travel if they were less healthy.
Participants enjoyed travel for its own sake and felt it was beneficial for their health and wellbeing. Cars and driving were seen as particularly important for discretionary travel. Community travel users felt discretionary travel needs were fulfilled but saw the formality and lack of spontaneity as negatives whilst participants who received lifts from family and friends felt a burden when travel was discretionary. Semi-structured interviews were the predominant data collection method; focus groups, walk-throughs and participant observation were also used. Prompts were used to aid data collection, including photographs taken by participants (one study) and separately collected participant accelerometry data (two studies). Most studies (N = 11) used one method of data collection; three used two methods.
Together, the studies reported the experiences of over 340 older people, with sample sizes ranging from five to 60. All participants were aged 60 and over. In eight of the studies, participants were aged 65 and over; in five of these, participants were aged 70 and over (see Table 1). Participants lived in advantaged and disadvantaged communities in inner-city, urban and suburban areas in England, Scotland and Wales. Limited information was provided on co-habitation status (five studies); in these studies, approximately half the participants lived with a partner. Limited information was also given on ethnic background (six studies); in these studies, it was clear that the majority of participants were White.

Analytical themes
Four inter-connected themes were identified. Each theme pointed to the intrinsic value of travel, a value particularly evident in the first two themes.
The first two themes related to 'getting out' and being an independent traveller. Together, the themes made clear that travelling in the local environment was not simply a means to an end. The process of travel had its own meaning. It was an act and an experience from which older people derived enjoyment; participants therefore often referred to its contribution to their wellbeing. The third and fourth themes highlighted the ways in which environmental and transport-related factors mediated older people's travel experiencesand therefore determined the extent to which the intrinsic as well as the extrinsic value of travel could be realised. Studies focused on older people's experiences of their local environment and local travel systems, respectively, contributed most to these themes.
The four themes were discussed with the project's policy advisers who offered insights and refinements. While confirming the salience of the themes, suggestions were made about strengthening the underlying message of our review about the value that older people attach to the process of local travel: namely its potential to be identity-affirming and a space for social interaction and community engagement. The section below takes account of this feedback. The four themes are discussed in turn, with their interconnections illustrated in participant accounts. In line with our focus on older people's experiences, these are given priority in the presentation of our findings.

Analytical themes
The importance of getting out The study participants made clear that travelling in the local environment was not simply about reaching destinations. Travelling was also an end in itself.
The intrinsic benefits of local travel had multiple and inter-related dimensions. Firstly, the act of 'getting out' was a way of countering the isolation of the home; as Sixsmith and Sixsmith (2008: 288) observe, the home can be 'a place of intense loneliness': It's the easiest thing in the world just sitting there, just read or do something. You've got to get out; you've got to move about. (Guell et al., 2016) I could easily sit here all day … you know, especially if the weather is bad and you can't get out … but it's no good you've got to make an effort … I make myself go out to a certain extent … I hate every minute I live on my own. (Sixsmith and Sixsmith, 2008) Having a walking companion could encourage and enhance the enjoyment of getting out, while a partner with limited mobility could constrain travel options (Day, 2008(Day, , 2010Stathi et al., 2012;de Koning et al., 2015;Milton et al., 2015, Guell et al., 2016: We used to go there (the supermarket) more frequently, but now she can't walk much, we don't walk down, we take the car down. I know it's stupid for about 400 yards. (Stathi et al., 2012) Secondly, getting out offered opportunities to 'see life' and feel socially connected. Across all the studies and across all travel modes, older people spoke about these personal benefits. These benefits were particularly evident for travel modes supported by public funds. For example, with respect to walking, the following accounts were typical: I don't like sitting … and just watching telly or, I've got to be on the go. So … I do like every day, at least, to get out in the fresh air, have a little walk, even if it's only for an hour, just down the city, you know, or anything. (Guell et al., 2016) So you walk down the street … 'good morning, lovely day, how are you keeping, you've got a stick, what happened?' that kind of thing. And people talk to you. (Day, 2008) Participants described the benefits of travelling by bus and using community transport in similar ways: I get out every day because I get bored living alone in the flat, so I get out every day, catch the bus, sometimes two, three buses a day. (Green et al., 2014) Getting out and about [using community transport] you still see things. You see life going on around you. You don't experience or feel that at home. (Musselwhite, 2017a) Being disabled … and more or less housebound the community transport enables me not only to be able to get my weekly shopping but to meet other people. (Musselwhite, 2017a) 854 H Graham et al.

Being an independent traveller
The second theme relates to the importance of remaining independent, despite mobility limitations and financial constraints. Older people value travel systems and environments that support, and do not compromise, their strong preference for independence. Two inter-connected dimensions were evident: decisional autonomy and self-reliance. The importance of being free to make travel decisionswhat Schwanen et al. (2012Schwanen et al. ( : 1317 describe as 'freedom to', was evident across the studies (Sixsmith and Sixsmith, 2008;Schwanen et al., 2012;Stathi et al., 2012;Green et al., 2014;Musselwhite, 2017a). Everyday travel, whether by foot, car or bus, provided a way of enacting one's 'freedom to'; independent out-of-home mobility was therefore highly valued. This was captured in the comments of one study participant: If I never had my bus pass, I wouldn't have the freedom that I've got. I go to clubs … Which helps me to, you know, do the rest of the week, so it's not so long. (Green et al., 2014) The car was particularly valued as offering a latent capacity for mobility, what Musselwhite (2017a: 55) refers to as 'potential for travel': That's what the car does you see. Takes you where you don't need to go, you see. And for me that's life. (Musselwhite, 2017a) I don't feel I have the freedom that I do with the community transport as I did with a car. I am taken places. It's nice but I miss the freedom to choose, the journey, how long we stay and so on. (Musselwhite, 2017a) Intertwined with freedom to make travel decisions was being self-reliant and, specifically, not being dependent on family and friends to meet one's travel needs. The desire to remain self-reliant for as long as possible was a constant refrain. Driving a car, taking the bus, walking with mobility aids, using community transport and, for those who could afford it, taking taxis were all seen as preferable to depending on family and friends: I couldn't have a better family but I still don't want to be dependent and don't want to be a nuisance to anybody. (Schwanen et al., 2012) [By using community transport] I'm not a burden to them. They're busy, they wouldn't be able to take me about you see. (Musselwhite, 2017a) I don't like keep asking 'can I go there?' while I can manage it, and that's why I bought my two-wheeler [rollator]. (Schwanen et al., 2012) As the accounts above indicate, travel represented an important arena in which to exercise agency. Together, being able to make everyday travel decisions and be self-reliant in enacting them demonstrated independence and helped to avoid the connotations of dependency associated with being old (Sixsmith and Sixsmith, 2008;Schwanen et al., 2012, Stathi et al., 2012Green et al., 2014;Musselwhite, 2017b). Being an independent traveller signified and enacted a broader capacity for independence in old age as the accounts below illustrate: I appreciate the fact that I can get out and about and I can do things for myself, it helps me to remain independent. And I can go out and do my shopping, get my paper, travel. If I travel I, you know, I could do it if I need. (Schwanen et al., 2012) The car is a symbol of my freedom and my ability still to be in control. (Musselwhite, 2017a) I desperately wanted to … go into the recreation ground, because that had been our stamping ground when we were young … And the day I did that, I came back and … I felt marvellous! And I was going … round streets … and looking at people's gardens and, yeah, … I felt taken out of myself! (Schwanen et al., 2012) The importance of the local environment The first two themes point to the intrinsic value of local travel for older people. Its instrumental value was also emphasised: travel provided access to local facilities and social networks. Travelling to a destinationthe official definition of personal travelwas also a spur to getting out, giving structure and focus to the trip and enhancing its opportunities for social interaction. Across the studies, participants spoke about how the availability of local amenities and, in particular, food stores, newsagents and post offices, influenced their motivation to, and experience of, travel (Parry et al., 2007;Day, 2008Day, , 2010Schwanen et al., 2012, Stathi et al., 2012de Koning et al., 2015;Milton et al., 2015). Thus, living close to amenities facilitated getting out (de Koning et al., 2015) and 'street socialising' (Day, 2008: 308). As two participants in the study by Stathi et al. (2012) observed: You got a hardware shop, and you got bakers, greengrocers shop, hairdressers, you got dentist, you got a library, so there's lots of, there's fish and chip shops, a lot of take-away shops all up there. It's all in one; you could go up there and get everything what you wanted, really.
Whenever you go to up the top [of the high street] there's always somebody stopping, you have a few words and chat and things.
A more common experience, particularly among older people in disadvantaged areas, was the loss of these local centres, and the consequent need to travel beyond the local area to access the services they needed. As Milton et al. (2015) note, older people lamented the loss of local amenities, particularly those seen to be the 'hub' of the community.
There's nothing in this area … not even a swing for a child … nothing for old or young. (Milton et al., 2015) 856 H Graham et al.
[In the past] each area had all these shops, you could buy here and there, and cross the road and get so many things on the other side. It was lovely, it was an outing … Everybody used the local shops and you met people practically every other day. You could meet and stand and blether to people for as long as you liked. But that's what I am saying, the companionshipthat's gone now I think. (Day, 2008) In addition to local amenities, the studies point to a range of environmental features that impacted on older people's experiences of travel. Many of these features are captured by what Zandieh et al. (2016: 2) refer to as 'the micro built environment', a concept that includes pedestrian infrastructure, aesthetic appearance and personal safety.
The pedestrian infrastructure includes streetscape design, with study participants describing the importance of benches, toilets and bus shelters for enabling walking and bus travel as well as facilitating social interaction (Day, 2008(Day, , 2010Sixsmith and Sixsmith, 2008;Stathi et al., 2012;Guell et al., 2016;Zandieh et al., 2016).
The infrastructure for walking also included traffic conditions and pavement quality, where pavement width, surfaces and road crossing points were particularly highlighted: And the high kerbs, so if we are going to a certain place we have got to say 'now we have got to go along there and there's a low kerb there, and go down here, but I have got to cross there and move along there'. You can't just go from A to B. (Day, 2008) I used to go across the road. But I stopped going there because again, if I was crossing the road, I could fall down. I don't need anything to fall over, I just fall down. And you know … a driver, who couldn't stop in time to stop running over you. And I've got no intention of being run over. (Sixsmith and Sixsmith, 2008) I confess I do go outside my house, but only in the quiet times. I look very carefully [for crossing the roads[. I can say I stop halfway, on the white lines you see in the middle of the road. (Zandieh et al., 2016) The studies included examples of where travel was impeded by uneven pavements with broken bottles and pavement obstructions, e.g. cars parked across the pavement area. As one participant put it: When we walk up here, we have to be very careful! Broken bottles and broken pavements! … Broken pavements and slope! It would definitely mean you have to watch. (Zandieh et al., 2016) Aesthetics refers to 'a sense of beauty and visual appearance of a neighbourhood' (Zandieh et al., 2016: 2), e.g. natural features and enjoyable places to walk. As a participant in Day's study noted: Studies included descriptions of how the natural environment, even in a miniaturised form of flower tubs in the shopping centre, enhanced the aesthetic enjoyment of the local environment and engendered a sense of civic pride (Parry et al., 2007;Day, 2008;Zandieh et al., 2016). Along with architecturally varied buildings, study participants noted how flower beds and trees as part of the streetscape and well-maintained front gardens with flowers encouraged walking and increased the enjoyment of doing so (Day, 2008(Day, , 2010Davis et al., 2011;Stathi et al., 2012;Zandieh et al., 2016): I think it [nice flowers and gardens] brings you back to nature and makes you realise there is more to life. Even just sitting watching flowers, looking at the flowers, the different colours, the different shape of the petals and all that, you could spend ages. (Day, 2008) It (my neighbourhood) is boring. These little industries are around. There is not many pretty gardens and places to look up regularly. You can see all industries over there! (Zandieh et al., 2016) There's plenty of greenery around here and it's quite nice to take a walk up 'round. (Stathi et al., 2012) Other aspects of the local environment, like air quality and quietness (Day, 2008(Day, , 2010Stathi et al., 2012;Hammond and Musselwhite, 2013;Zandieh et al., 2016), were also described in terms of their impact on older people's enjoyment of travel. I like peace and quiet. I like, I mean you can hear yourself. (Day, 2008) I like fresh air and exercise. This area has a good air quality because of the [few] cars. (Zandieh et al., 2016) Accessing and enjoying the local environment were also affected by changes in the weather and across seasons (Sixsmith and Sixsmith, 2008;Schwanen et al., 2012;Stathi et al., 2012;de Koning et al., 2015;Milton et al., 2015;Zandieh et al., 2016). As Milton et al. (2015) note, there is a seasonal variation in older people's travel environment; in winter, their neighbourhood reduces in size. Cold and wet days were avoided, particularly if adverse weather conditions made pavement surfaces slippery: I mean I don't like going out when it is icy or snowy because I wouldn't want to fall down or anything like that. (Stathi et al., 2012) We wouldn't go [walking] if it was raining! (de Koning et al., 2015) Older people's concern for their personal safety was discussed in the majority of studies (Parry et al., 2007;Day, 2008Day, , 2010Sixsmith and Sixsmith, 2008;Stathi et al., 2012;Green et al. 2014;de Koning et al., 2015;Zandieh et al., 2016). As Parry et al. (2007: 126) note, 'fear provides a key nodal point in residents' accounts', particularly for women (Zandieh et al., 2016). The studies described how fear was environmentally determined, with particular times of the day (after dark and at night) and settings (e.g. being in proximity to groups of young men) perceived as particularly unsafe. Older people 'segregated themselves in time' (Day, 2010(Day, : 2667, going out in the morning and avoiding night-time to reduce the risk of being in situations perceived to be potentially threatening: I wouldn't walk down there at night. No way. Well I wouldn't even get out the car, 'cause the pub on the corner it's always got plenty of people round it you know. (de Koning et al., 2015) Gangs hang around outside and you walk around not without their prejudice. You are not one of them … they won't let you to pass through! They will come right up to you when you want to move! (Zandieh et al., 2016) I've been into town, and I've come up the road and I mean there were five young fellas coming down the road, and I thought to myself: 'Do I have eye contact?' cos I like to, I like to have eye contact with people, you know, and I thought: 'No, just keep your head down'. (Parry et al., 2007) I don't like going through the passageway [a narrow street between buildings] on my own … I'm not very keen on going through there because there's like high fencing, and there's nobody about, and well … I mean, it's not a walk for a really elderly person to do on their own. (Stathi et al., 2012) A consistent finding across the studies was the area-based inequalities in the micro built environment. Older people in disadvantaged areas were more likely to perceive their local environment as having a poor pedestrian infrastructure, lacking beauty and being unsafe.
Participants in disadvantaged areas spoke about the lack of benches and toilets, with those available vandalised and no longer usable (Day, 2008;Sixsmith and Sixsmith, 2008;Stathi et al., 2012;Zandieh et al., 2016). They spoke about rubbish on the streets and in alleyways, with bins overflowing, rubbish bags on the street and litter outside take-away food outlets (Day, 2008;Zandieh et al., 2016). They described traffic density, traffic pollution and roads that were difficult to cross (Day, 2008;Sixsmith and Sixsmith, 2008;Stathi et al., 2012;Zandieh et al., 2016), and their accounts pointed to heightened concerns about their personal safety. For example, Zandieh et al. (2016: 13) noted how participants in the high-deprivation areas in their study described their fears about 'gangs and groups of hooligans dominating pavements and their anti-social behaviour as well as high crime rate, drug use and lack of street lights'. In contrast, a resident in a lowdeprivation area observed: There is nothing to frighten anyone, there is no real crime on this area. You know, no vandals around the streets. So, no frightening people. (Zandieh et al., 2016) Given these very different environments, older people in disadvantaged areas were more likely to limit walking to instrumental journeys and have fewer opportunities to experience the intrinsic benefits of getting out; as Day (2008: 307) observed, 'few actively enjoyed the environment'.

The importance of local transport systems
It was not only the quality of the local environment that determined the benefits that could be derived from everyday travel. They were determined, too, by the local transport system.
Firstly, older people discussed the provision of local travel facilities. As one study participant put it: Transport is a very important factor in terms of my lifeor lack of transport. (Sixsmith and Sixsmith, 2008) The availability, accessibility, connectivity and comfort of travel modes were all discussed. For example, as the accounts below indicate, walking was facilitated by the availability and accessibility of traffic-free routesand by a local bus service that enabled older people to combine travel modes: Yesterday we walked down [to the seafront] from here and took a rest and then finished up going almost to [X]. Coming back, catching the bus and coming home. (Day, 2008) We used to catch a bus and go up on the bus and have a little walk, have an ice cream, have a rest, and come back. But you can't do that now because we've got no buses. (Milton et al., 2015) While the intrinsic benefits of car travel (see the first and second themes) were discussed, having a car was also often explained in terms of the lack of suitable alternative travel modes.
Of course buses stop at 6 o'clock so you need a car if you want to get out in an emergency or anything like that, or go out to the theatre. (Schwanen et al., 2012) Quite frankly I don't know how we'd manage if we didn't have the car. (Zandieh et al., 2016) You don't need a car but it's surely handy to have one. Because you've got a 10-minute walk down to the bus … and the buses are not terribly reliable as you probably read in the paper. (Stathi et al., 2012) Travel-focused studies noted how the cost of a travel mode was integral to older people's assessment of its availability. While taxis offered a quick door-to-door service, they were expensive and were therefore not regarded as a mode of everyday travel (Sixsmith and Sixsmith, 2008;Schwanen et al., 2012). Conversely, the free bus pass scheme facilitated everyday travel, as the following accounts illustrate: That is one good thing about living here, an excellent bus service … and, costs me nothing. I would say probably four times, four days a week. (de Koning et al., 2015) Well, I use it every day … And if I didn't have a Freedom Pass, I wouldn't be able to go out every day. Because I've got sticks, so I can't walk very far. (Green et al., 2014) It's a godsend, because, it's very lonely where I am, although it's sheltered housing, and you've got your flat, and you'd be lost without it. It's the only thing I have that gets you around. (Green et al., 2014) It was not only the physical and financial aspects of different travel modes that mattered for older people. The studies pointed to the importance of the social worlds of travel. As the accounts below indicate, walking, taking the bus and using community transport enabled them to enter and be part of this wider public sphere: [Walking the dog] it's marvellous for meeting people … they'll wave as they know it's my time. So I have made quite a few friends just through the dog. (Milton et al., 2015) Everybody was saying, oh gosh we don't often see you on the bus! Because it's quite a social occasion for a lot of these ladies … because they all meet up, you know, if they're on their own and they don't see many people, it's quite nice. (Milton et al., 2015) You want something to help your life along. I find that people do speak to you on the bus. (Green et al., 2014) It's a weekly catch up with friends basically! I really look forward to a good chinwag on the [community transport] bus. (Musselwhite, 2017a) Strengths and limitations Our review drew on the experiences of over 300 older people living in the UK's urban areas. Health, social science and transport databases were searched, providing access to relevant research across a broad range of research fields and disciplines.
The breadth of studies included in the review enabled us to highlight the multilayered connections between wellbeing, travel and the local environment. However, the focus on the urban environment means that older people living in rural areas were excluded. A separate review of these studies is in progress. The breadth of the studies also means that the review does not provide in-depth analysis of all dimensions of older people's experiences of everyday urban travel. To give two examples, the experience of driving cessation and of fear for one's personal safety are noted but not discussed in detail; this more detailed treatment is provided in bespoke reviews (e.g. Lorenc et al., 2013, Musselwhite, 2017a. Two sets of papers are drawn from the same studies (Day, 2008 andJones et al., 2013 andGreen et al., 2014). As a check, we examined their contribution to the themes (Noyes et al., 2018). This confirmed that the papers focused on different dimensions of the experience of everyday travel in the local environment and made a separated contribution to the thematic synthesis.
Few studies (N = 5) provided information on the household circumstances of participants; these studies note that around half were not living with a partner (see Table 1). UK data point to marked gender differences in the domestic circumstances of men and women, with women aged 65 and over much more likely to be living alone than men in this age group. By age 85, less than one in ten women are living with a spouse or partner, compared with over a third of men (Dunnell, 2008). As this suggests, there is an important gender dimension to the experience of the home as a lonely place and to the value that older people attach to getting out and about in their local environment. Our review could not explore this dimension but it would warrant further study.
The perspectives of frailer older people are likely to be under-represented in our review. Studies recruiting participants on the basis of their health condition were excluded and only two of the included studies noted that some participants were living in care settings. Care home residents are a group highlighted by our policy advisers as facing particular difficulties around everyday travel, and therefore with accessing basic services and social networks (Barnes et al., 2006). We recommend that a future review should focus on the travel needs and experiences of older people in care homes, to complement and add depth to qualitative reviews of their broader experiences (Lee et al., 2009;Bradshaw et al., 2012).
The studies were located in both more-and less-disadvantaged areas of urban Britain, and the majority included information on the area deprivation profile and/or gave details of the socio-economic circumstances of the participants (Table 1). Our synthesis pointed to marked social inequalities in older people's everyday travel experiences. Everyday travel for more disadvantaged groups depended on walking and bus travel, with the latter made possible by the concessionary bus scheme and by an accessible and frequent bus service. Social disadvantage was also structured into the localities in which they lived; these localities were characterised by micro built environments that were less easy and enjoyable to walk in. Compared to those living in more advantaged areas, older people in poor urban environments described a pedestrian infrastructure that was more hazard-strewn and harder to navigate, particularly for those with mobility needs. They spoke, too, of a physical environment that engendered less sensory enjoyment and civic pride, and a social environment more likely to generate anxieties about personal safety. As this suggests, there are powerful environmental determinants of active travel (Owen et al., 2004).
While the impact of social disadvantage is discussed, the studies shed less light on how ethnic and cultural background shapes older people's experience of travelling in the urban environment. Six studies provide information on ethnic background, noting that all or the majority of the participants were White British. However, no studies reported the ethnic background of participants whose accounts are quoted in the studies and only two referred to culturally important venues, like places of worship and traditional food outlets (Green et al. 2014;Milton et al., 2015).
The limited information on ethnic background suggests that our review captures the experiences of local travel for the UK's majority ethnic group. The themes and findings that emergedthe intrinsic benefits derived from 'getting out' and feeling part of the wider community, being fearful about travelling at times and to places where one feels at riskmay be experienced differently by older people from minority groups, particularly in areas scarred by ethnic tensions. With the ageing of the UK's minority groups (Lievesley, 2010), qualitative studies that capture ethnic and cultural diversity in older people's experiences of travelling in their local environment are urgently needed.
The thematic synthesis was shared and refined in discussion with policy advisers working at local, metropolitan and national level. They confirmed the salience of the four themes and made two broad sets of observations.
Firstly, those directly engaged in supporting the wellbeing of their population (e.g. in primary care and through cross-agency wellbeing plans) emphasised the importance of our findings around the value that older people attach to the process of travel: to being 'out and about' in their locality. This key finding was seen as particularly relevant at a time of reductions in local government funding and the increasing emphasis on locally driven strategies to improve wellbeing. As this group of advisers noted, our review highlights how older people are motivated by both the intrinsic value (getting out) and extrinsic value (getting there) that travel in the local environment offers them. They noted the potential contribution that enhancing the enjoyment of local travel could make to improving quality of life in older age and, more broadly, to promoting community cohesion. The feedback from our advisers suggested that older people were an instructive case study for local policy making and service delivery. From the older people's experiences, general principles could be derived to enable policy makers and planners to meet the travel needs of the whole population better.
Secondly, the project advisers noted that the themes may relate more strongly to the experience of older people without mobility needs than to frailer older people and those in care homes, an observation consistent with the selection criteria for the review and the participant profile of the individual studies within it (discussed above).

Discussion
In both research and policy, local travel is seen primarily in terms of the destinations that it enables people to reach. It is an instrumental activity undertaken to access other sites: the shops, the doctor's surgery, leisure facilities, and the homes of family and friends.
The extrinsic value of local travel and transport systems for older people came out clearly in our synthesis. In some studies, participants lived close to local amenities and spoke about how having these facilities in one place meant their everyday travel needs could be easily met. A more common experience was of losing the local services on which they had previously relied. For both groups, local travel facilities were key, including their availability (including in the evening and at weekends), connectivity (e.g. walkways that connected with local buses) and cost. For those on low incomes, it was clear that, in line with quantitative evidence (Mackett, 2015), the concessionary bus scheme promoted accessibility to facilities. Our findings therefore lend weight to policies that seek to improve and equalise access to transport, e.g. by investing in the pedestrian infrastructure and in concessionary bus fares for older people.
Our analysis also supports a broader perspective. It suggests that everyday travel is about more than moving from place to place, and transport is more than the means by which this movement takes place. As Ziegler and Schwanen (2011) and Parkhurst et al. (2014) note, reaching destinations captures only one aspect of the process and experience of mobility. Classifying travel by trip purpose and destination can obscure these broader meanings, including 'the importance of engagement with the familiar locale' (Parkhurst et al., 2014: 128). In a similar vein, Musselwhite (2017aMusselwhite ( , 2017b argues that travel serves a 'hierarchy' of mobility needs, from primary (practical) needs, through secondary (social and affective) needs to tertiary (aesthetic) needs. A single journey can therefore meet multiple needs.
It is this broader understanding of everyday mobility that our synthesis brings out. It points to the importance of travel for its own sake, and the wellbeing benefits that older people experience from the act and process of travelling in their local environment. These benefits are evident in all four themes. Under the first theme, older people spoke of 'getting out' as a way of counteracting the loneliness and tedium of home life and enabling them to feel part of a wider social world. Under the second theme, older people described the meaning of personal travel, stressing the value they attached to making autonomous travel decisions and being self-reliant in enacting them. All modes of transportcars, public transport, community transport, and walking with or without mobility aidswere described in these terms. They were valued because they enabled older people to be independent and to demonstrate this capability to others, particularly to family members.
The third theme turned the spotlight on how the contexts of everyday travel mediated its potential benefits. The pleasure of getting out and the opportunity to be independent depended on the quality of the local environment and its travel systems. Thus, with respect to the local environment, study participants noted that they depended on physical features and amenities (including benches, toilets, wide pavements, safe crossing points), along with their state of oversight and repair (e.g. vandalised benches, uneven pavements, broken bottles). Fear compromised the enjoyment of travel and limited travel opportunities, with older people avoiding times and places where they felt unsafe. Aesthetic appearance was integral to the psycho-social benefits of everyday travel, with participants noting the pleasure they derived from an area's architecture, quietness, air quality and natural features. The importance of aesthetic appearance is well recognised with respect to urban parks and green spaces. As a review of qualitative studies of urban parks notes, 'natural' features like colourful displays of flowers, well-tended gardens and a sense of fresh air are among the attributes that people value (McCormack et al., 2010). Our review suggests that these attributes also matter for everyday travel, with aesthetic features both motivating local travel and increasing its enjoyment.
The intrinsic benefits of travel come out again in the fourth theme. Local travel systems, and the travel modes that they sustain, are obviously a prerequisite for travel. But our review makes clear that they are valued not only to reach destinations; older people value the social connections that travel modes make possible. The accounts of older people suggest that, when they travel as pedestrians, bus travellers and users of community transport, they become part of communities that make a vital contribution to their wellbeing. In consequence, their everyday travel may be experienced as more enriching and health-enhancing than the activities at its destination, a feature also noted about journeys to holiday and tourist destinations (Parkhurst et al., 2014).
Among the different travel modes, walking and bus travel stood out for their potential to enable older people to reach destinations and to meet important psycho-social needs. Travelling by foot and by bus, supported by the national bus pass scheme, are both free. Singly and together, they can enable older people to get outand to enjoy being independent, self-reliant travellers and part of the wider community. Investment in the pedestrian and public transport infrastructure can also support active travel and reduce the environmental costs of road transport, by reducing fossil fuel emissions, noise pollution and traffic accidents (Woodcock et al., 2009;Hickman and Banister, 2014). These benefits bring further dividends for both older people and wider society.
In conclusion, our review of older people's experiences makes clear that the enjoyment of travel as well as its functionality matters. Both provide principles to guide policy development and decision-making. As our policy advisers suggested, existing travel systems and future investments could be assessed not only in terms of whether they enable people to reach destinationsbut whether, additionally, they maximise the opportunities for people to enjoy and derive benefits from being 'out and about' in their local community.
