Viability of Social-Network Based Transit Information Systems for Accessibility

This project researches the viability of social-network-based transit information systems; specifically, Tiramisu, a crowd-powered transit information system developed by researchers to improve users’ transit experiences and transit accessibility. Accessible public transportation is critically important. However, the current state of accessible public transportation is a barrier to social participation and employment. Tiramisu, Italians for "pick me up," addresses these issues and improves the transit experiences of individuals with disabilities through valuable, real-time information about accessibility details (e.g., bus fullness) and vehicle arrival times (i.e., exposure to inclement weather, and crime). With Tiramisu, anyone waiting at a bus stop with a smartphone can see which buses or light rail vehicles are due to arrive next, thanks to the information provided from riders already aboard, and get an idea of how long they have to wait. The extension of Tiramisu within social networks allows communication between riders as well as between riders and transit agencies.
