OCCUPANCY DETECTION TECHNIQUES FOR TRANSIT SYSTEMS

A relatively simple and inexpensive method of verifying one of the most crucial functions in transit systems, that of continuous verification of train location is presented. While the system described is based primarily on hardware implementation, it would be relatively easy to implement the off-train logic using redundant minicomputers and software logic. While more sophisticated techniques could be developed, many present and future systems could adapt themselves to this technique, thereby increasing their reliability and safety.
