Accession Number: 00625683
Record Type: Component
Availability: Find a library where document is available Abstract: INFORM (Information for Motorists, formerly known as the Integrated Motorist Information System, or IMIS) is a corridor traffic management system designed to obtain better utilization of existing highway facilities in a 40-mi highway corridor on Long Island, New York. The system includes integrated electronic traffic monitoring, variable message signing, ramp metering, and related strategies to optimize traffic flow through a heavily congested corridor. The evaluation of INFORM was conducted using extensive field data, perception surveys, and data collected through the system. The overall results of the evaluation are presented, including comparisons of vehicle miles of travel, average speeds, ramp delays, motorist perceptions, and other congestion-related measures for the a.m. and p.m. peak periods. Incident case studies were used to evaluate motorist response to and effectiveness of variable message signing strategies. In addition to a summary of the quantitative results, an overview of the many lessons learned in the design, implementation, operation, and evaluation of INFORM is provided.
