COLLECTION AND EVALUATION OF PROJECTED TIME GAP USING CAMDAS

This paper focuses on the issue of time gap and river gap acceptance behavior. It presents an approach for extracting the projected time gap measure from videotaped traffic scenes using the CAMDAS video image processing (VIP) software. The approach extracts the distance gaps as well as the projected time gaps. The paper describes and evaluates the relationships between time gap, distance gap, project time gap, and the major- and minor-road vehicle speeds.
