Pedestrian navigation and integration with distributed smart signal traffic controls

Pedestrians with special needs encounter accessibility challenges and are exposed to even greater risks when using signalized traffic intersections. Even modern accessible pedestrian stations present significant challenges for pedestrians with physical and sight disabilities. This paper describes an interactive traffic controller for allowing the intersection to receive pedestrian call requests from users with special needs and for providing the user with guidance and signals status feedback information from the intersection. Feedback from the intersection enables individuals with low vision to know the state of the intersection, as well as receive guidance from the traffic controller based on the pedestrianpsilas location.
