THE NEED FOR A METHOD TO PROVIDE SURVEILLANCE OF ROADWAYS HAS GENERATED RESEARCH FOR MANY AGENCIES, INCLUDING THE GENERAL MOTORS RESEARCH LABORATORIES (GMR). THE DETROIT DEPARTMENT OF STREETS AND TRAFFIC IS CURRENTLY OPERATING THE GM-SPONSORED CB RADIO DRIVER AID NETWORK. THIS SYSTEM MAKES POSSIBLE THE REPORTING OF TRAFFIC-RELATED INFORMATION SUCH AS ACCIDENTS AND TRAFFIC FLOW INTERFERENCE. ON THE BASIS OF EARLIER DEMONSTRATION EFFORTS, THE SYSTEM HAS BEEN EXPANDED TO COVER THE ENTIRE DETROIT SYSTEM OF SURFACE STREETS AND FREEWAYS. THE SPECIFIC FUNCTIONAL ASPECTS OF THE SYSTEM AND A DESCRIPTION OF ITS MAJOR TECHNICAL EQUIPMENT ARE GIVEN. THE PAPER DISCUSSES THE RESULTS OF THE EARLIER OPERATIONS, PRESENTS DATA ON CURRENT OPERATIONAL ACTIVITIES, FINDINGS OF A QUESTIONNAIRE SURVEY, AND REACTIONS AND CONCLUSIONS RESULTING FROM THESE EFFORTS. THE SYSTEM IS VIEWED AS PROVIDING A FEASIBLE INTERIM SOLUTION TO THE PROBLEM OF ROADWAY SURVEILLANCE, INCIDENT REPORTING, AND ACTION IMPLEMENTATION TO PROVIDE SAFE AND EFFICIENT TRAFFIC FLOW. /AUTHOR/
