Implementing Connected Vehicle Infrastructure (CVI) applications for handheld devices into public transportation transit systems would provide transit agencies and their users with two-directional information flow from traveler-to-agencies, agencies-to-traveler, traveler-to-vehicle, and vehicle-to-traveler. This information flow could improve the efficiency of services provided by the agency and enhance the safety of travelers and drivers. This project developed an architectural framework for two CVI applications: (1) an application for dynamic demand-response transit (DRT) services and (2) an enhanced traveler safety application that allows individuals to notify a transit vehicle that they are within a specified distance of the vehicle’s current stop location. A limited simulation was performed to evaluate the potential of using this location information with respect to a transit vehicle to provide flexibility for that vehicle to remain at a stop for a limited time, minimizing passenger wait time and exposure to potential safety issues, specifically during night operations. An annotated bibliography of resources used for this study is also provided.
