DEVELOPMENT AND TESTING OF INCIDENT DETECTION ALGORITHMS, VOLUME 1: SUMMARY OF RESULTS

The development and testing of incident detection algorithms was based on Los Angeles and Minneapolis freeway surveillance data. Algorithms considered were based on times series and pattern recognition techniques. Attention was given to the effects of geometrics, sensor configuration and weather, and methods were developed for detecting malfunctioning sensors and for identifying the lane of an incident. This, the first volume, provides a summary of the methodology developed and used in this study, results obtained and recommendations for implementation. /FHWA/
