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.

摘要： Pedestrian call systems with bidirectional communication between pedestrian call stations and traffic controllers are arranged so as to detect system errors, to provide the ability for pedestrians to provide input as to the need for the system to provide an opportunity for the pedestrian to cross the intersection, and to provide notification capability in the event of an emergency. Communications are provided via wireless communication devices, and systems can be configured and monitored using a web browser. In one example, traffic systems are provided with wireless interfaces that can be used for bidirectional communication.
