Patent Images
1. A system, comprising:
- one or more sensors configured to detect one or more characteristics of traffic incident to a roadway intersection and to provide corresponding signals;
a memory configured to store traffic information according to the signals provided by the sensors;
a knowledge base including one or more traffic control algorithms defined by a user;
an inference engine configured to derive one or more control signals using the traffic information stored in the memory and the traffic control algorithms stored in the knowledge base; and
a signal driver configured to actuate at least one multi-state traffic control signaling device according to the control signals.

Abstract
A system includes a plurality of sensors that provide information regarding instantaneous traffic conditions incident to an intersection. An inference engine of the system receives the sensor information and processes user-defined traffic control algorithms and weighted management parameters. Control signals are derived in accordance with the processing. Multi-state signaling devices are driven in accordance with the control signals so as to manage vehicular and pedestrian traffic flow at the intersection. Playback of historic traffic information permits analysis and verification of the traffic management strategies implemented by the system.
