Enhancing Accessibility Information in Google Maps Adding new pieces of information to GTFS to improve accessibility

Google is the most important information provider on Internet. Within the Google ecosystem, Maps is a relevant tool, which is used to calculate routes and to find points of interest. As part of this effort, it has defined Google Transit Feed Specification (GTFS), a format to specify data of public transport. Now public transport agents can provide a "feed" complying with this specification and Google can use them and represent them on Maps. In spite of their relevance for accessibility in mobility, Google Maps does not offer detailed information about accessibility facilities to transit, and GTFS does not specify the necessary structure to provide that information about public transport. In this work, we propose an extension to GTFS to provide relevant data to represent accessibility elements on Google Maps and similar systems to offer different social accessibility services.
