A study was performed to determine the feasibility of implementing an Integrated Motorist Information System (IMIS) in the northern Long Island Corridor of New York State. The objectives of IMIS are to demonstrate the benefits of an integrated approach to traffic management and to permit research in motorist information systems and advanced concepts in traffic flow optimization. In the study, extensive corridor data were collected and analyzed to determine candidate alternative routes and connecting roadways to be included in the system network. Trade-off studies were performed to identify the most suitable approaches and equipment types for implementing the IMIS features. Two traffic simulation programs were used to perform system configurational studies and develop fundamental benefit relationships for various control policies. A set of nine alternative system designs were developed, varying in network configuration, equipment complement, and functional capability. For each design, benefits, costs, and benefit/cost ratios were calculated. This is the Executive Summary volume.
