Advanced accessible pedestrian system for signalized traffic intersections

摘要

Pedestrian call systems with bidirectional communication between pedestrian call stations and traffic controllers are arranged so as to detect system errors. Communications can be provided over power conductors, and systems can be configured and monitored using a web browser. In one example, traffic systems are provided with Ethernet interfaces that can be used for bidirectional communication over power lines.

1. A pedestrian call station, comprising:
a pedestrian call switch operable by a pedestrian; and a pedestrian station processor coupled to the pedestrian call switch and configured to communicate a traffic control request to a pedestrian management unit in response to activation of the pedestrian call switch by the pedestrian and to receive an acknowledgment of the traffic control request from the pedestrian management unit, wherein the traffic control request is associated with controlling at least one traffic signal so as to allow or deny movement of vehicular traffic.
