This project will give researchers hands-on experience with the connected transportation environment and interactions among pedestrians, bicycles, vehicles, and traffic signals. Specifically, this project will integrate data from traffic control system signal phase and timing (SPaT) broadcasts along SR 522 north of Seattle within an application (app) that pedestrians and bicyclists will use on their mobile devices. Pedestrians will be able to use the app to request right of way and receive information on the status of the pedestrian signal. Bicycle users will be able to indicate their presence to actuate the traffic signal. All users will also be able to send/receive better quality information on their location within a crosswalk, bicycle lane, pathway, or vehicle travel lane. The project not only has the potential to improve intersection operations but has clear implications for helping increase the safety of all non-motorized road users, particularly those with vision impairments and other disabilities.
