The Minnesota Department of Transportation (Mn/DOT) began deploying Advanced Traffic Management Systems (ATMS) in the early 70's. The Interstate 35W just south of the Minneapolis Central Business District was experiencing severe reoccurring congestion. A system of ramp meters, TV surveillance cameras, and vehicle detectors were installed in a Traffic Management Center (TMC) was built to monitor and control the system. Until 1988 the system expanded slowly. In the fall of 1988 a major program expansion was declared with the goal of achieving total freeway system coverage for metropolitan freeways by 1995. New motorist information services and several deminstration projects were launched. The program has achieved much in spite of problems encountered. This paper addresses the program achievements; problems encountered and future plans.
