Resumen
People's life expectancy is increasing throughout the world as a result of improved living standards and medical advances. The natural ageing process is accompanied by physiological changes which can have significant consequences for mobility. As a result, older people tend to make fewer journeys than other adults and may change their transport mode. Access to public transport can help older people to avail themselves of goods, services, employment and other activities. Hence, public transport is important to older people's quality of life, their sense of freedom and independence. Within the European Commission funded FP7 project GOAL (Growing Older and stAying mobiLe), the transport requirements of older people were studied on the basis of five different profiles/groups of older people defined within the project, according to their ?fitness to travel?. It was found that easily-accessible information provision on public transport was important for all of these groups, but that the required content and delivery of the information varied between groups. Even though new technologies can provide useful real-time information in the palm of a hand, the study highlighted that devices and content are not user-friendly for many older people, particularly relating to web sites and ?apps? (applications, usually on portable devices). As the system developers target bigger markets from their economic point of view, many products do not address the requirements of specific groups of older people (e.g. those with mobility difficulties). However, this could change with the apps-based traveller information because of the relatively lower cost of apps development when data is available in an open data server. In this context, the on-going EC-funded TIDE (Transport Innovation Deployment in Europe) project is exploring the issue of open data for apps-based traveller information as one of the innovative urban mobility measures. The benefits of open access data is that it allows third parties (private or public) to access data and develop apps to provide information to users in a variety of ways according to user needs. For example, older people may need larger font displays and primary data only, while mobility impaired people may need information on walking distances and the existence of gradient, steps, seats, etc. Reviewing the international cases of open data implementation, the study found examples of authorities initiating the market by running competitions to develop apps for targeted groups such as older or disabled people. This paper will present the findings of the information needs of older people using public transport from the GOAL project and then explores the possibility of apps-based traveller information for them currently being looked at in the ongoing TIDE project. The aim here is to address information needs of older people particularly using public transport to make it more attractive in the 21st century.
