DEVELOPMENT AND TESTING OF INCIDENT DETECTION ALGORITHMS, VOLUME 4: PROGRAM DOCUMENTATION FOR CALIBRATION, EVALUATION, AND IMPLEMENTATION

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 detection malfunctioning sensors and for identifying the lane of an incident. This, the fourth volume, contains documentation of programs which can be implemented to provide the incident detection function in a real-time system, and programs which can be used for evaluating and calibrating incident detection algorithms. /FHWA/
