First Claim
Patent Images
1. A pedestrian call station, comprising:
- a pedestrian call switch operable in response to a request by a pedestrian;
a processor coupled to the pedestrian call switch and configured to communicate a traffic control request to a traffic controller in response to activation of the pedestrian call switch and to receive an acknowledgment of the traffic control request from the traffic controller.

Abstract
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.
