Abstract

This paper describes the work in the DRIVE project MONICA (Monitoring Incidents and Congestion Automatically), to develop a traffic monitoring/incident detection system for urban networks. A system for the automatic and continuous monitoring of traffic has been installed in the London Urban Traffic Control system. A database which is designed to receive, process and store traffic information produced by the SCOOT system has been modified and integrated into the London SCOOT UTC system. The system is currently operating on about 200 links in the Wandsworth and Croydon areas. Examples of screen displays showing trends in flow and daily profiles of delay are given. A system for detecting incidents has also been installed in the London UTC system. The original method tested uses information on the flow and occupancy over two consecutive detectors to detect an incident in the road space between them. The method has been extended to take into consideration information from surrounding detectors. This should make the system more robust as well as providing information on the level of congestion caused by the incident.
