Abstract: This Section improves upon the vehicle reidentification algorithm presented in Coifman and Cassidy (in press) for consecutive detector stations on a freeway; in the algorithm, a vehicle measurement made at a downstream detector station is matched with the vehicle's corresponding measurement at an upstream station. The work should be applicable to any detector technology capable of extracting a reproducible vehicle measurement, or vehicle signature. The algorithm is presented using measured vehicle lengths from conventional dual loop detectors; however it could easily be adapted to match other vehicle signatures, such as visual vehicle signatures from wayside cameras (e.g., MacCarley 1998), and vehicle dimensions from scanning laser radar (e.g., Larsonet al. 1998)
