PACIFIC RIM TRANSTECH CONFERENCE PROCEEDINGS. VOLUME I. ARTERIAL STREET INCIDENT DETECTION USING MULTIPLE DATA SOURCES: PLANS FOR ADVANCE

An advanced traveler information system demonstration called ADVANCE will be implemented on an arterial street network in the Chicago suburbs. This paper describes a system that will identify nonrecurring, capacity reducing incidents on the ADVANCE highway netork. The system will use 3 separate incident detection algorithms to process information from several distinct real-time data sources. A data fusion process will combine the otuput from these algorithms to make an overall assessment of traffic conditions on the network. The paper describes initial plans for implementing the incident detection algorithms and the fusion process using rule based systems and a neural network.
