Improving Incident Detection for Regional Control Centre Operator Support

This paper presents an new approach to Automated Incident Detection (AID) Systems for traffic management based on processing Closed-Circuit Television (CCTV) images. The authors note that these systems have not been widely deployed in England, primarily because of the false alert rates which have added unnecessarily to the workload of control room operators. The authors propose three components to improve the quality of the AID systems: probabilistic methods can be used to achieve improved incident detection by combining a number of data sources, including CCTV images and inductive loops; historic data on likely congestion and incident locations are incorporated when assessing alerts for their relevance to operators; and the resulting alerts are presented to control room operators in a minimally intrusive fashion. The authors describe an initial implementation based on this approach that is currently being developed for evaluation in the Highways Agency’s West Midlands Regional Control Centre. Preliminary results confirm that while installing a commercial CCTV AID system on existing Pan-Tilt-Zoom (PTZ) cameras can result in a high false alert rate, careful system design can deliver benefits that overcome the problems.
