The potential of intelligent vehicle highway systems for enhanced traveler security

The author addresses some of the possible security functions that could be applied to transit systems by utilizing the availability of automatic vehicle location systems, broadband digital communication systems, and other IVHS (intelligent vehicle highway systems) functions. Emphasis is placed on the opportunities for security enhancements under the IVHS component for transit, called Advanced Public Transportation Systems (APTS). Attention is given to such security measures as covert open mike, slow-scan TV, electronic fare collection and intermodal facilities
