This report addresses Task S of the Intersection Decision Support (IDS) project funded by Federal Highway Administration (FHWA) and Caltrans. The objective of Task S is to evaluate and select Commercially-Off-The-Shelf (COTS) and emerging technology products that could eventually be deployed at intersections as part of the IDS system. Many sensors were considered and every plausible detection technology was reviewed for this task. The emphasis was on finding sensors that detect and track vehicle movements. This effort started with establishing a background and general guidelines for what this task was set to accomplish. Then, our hypothesis and assumptions as well as our constraints and limitations to achieve our goals were clearly defined. At last, the evaluation criteria were established. / NOTE: Final rept. / Supplementary Notes: Sponsored by California State Dept. Transportation, Sacramento.
