Specifications include, but are not limited to: The Bay Area Infrastructure Financing Authority (BAIFA) is seeking responses to a Request for Information (RFI) regarding a potential upcoming procurement to pilot and eventually deploy a smartphone application to declare and verify vehicle occupancy in express lanes and/or high-occupancy vehicle (HOV) lanes. BAIFA is investigating the technological, institutional and legal feasibility of an app-based approach to change the current vehicle occupancy enforcement paradigm from manual police enforcement to mostly automated enforcement. BAIFA seeks careful consideration and response to questions provided in this RFI from smartphone app developers as well as toll system integrators, customer service center system integrators, customer service center operators, and other interested parties who may be asked to interface with app-based information.
