Alternative Performance Measures for Evaluation of Congestion - Congestion Analysis Model Update and Maintenance

L. N. Spasovic / D. Dimitrijevic / P. Borra

Traffic congestion has numerous negative effects on the movement of people and goods, economic productivity and the environment. These effects include increased travel times resulting in lost wages and decreased labor productivity, wasted fuel and cost associated with it, deteriorating air quality, and drivers stress, which can adversely affect safety, health, and labor productivity. In recent years these effects have come to the forefront of the publics concern. In order to quantify traffic congestion and its impacts on New Jerseys motorists, New Jersey Institute of Technology (NJIT) developed the Congestion Analysis Model. This is a computer software tool that estimates congestion costs, congestion related travel delay, and mobility indicators for New Jersey highways. The key advantage of NJITs model over other computer models developed for the same purpose is that it uses the New Jersey Congestion Management System (NJCMS) database to calculate travel delays and other congestion indicators. This project builds on the accomplishments of the previous work on developing congestion analysis software. Specific objectives of this project are to update the calculation methodology, improve softwares user interface, redesign the output tables to meet NJDOTs requirements, update software documentation, and provide limited technical support to NJDOT users.
