Integrated Construction Zone Traffic Management

This report describes the development of a work zone impact assessment procedure using a series of state-of-the-art dynamic network analysis tools as building blocks. The procedure was implemented into a work zone traffic impact assessment software package known as NetZone. This software package is used to estimate time-dependent travel demand based on link counts, estimate demand diversion in response to work zone delay and various traffic management measures, show traffic congestion level in the network over time, and provide network wide traffic performance measures with and without traffic congestion mitigation measures. Results from a preliminary case study showed that NetZone can be used to study a reasonably large network in a fraction of time that a micro-simulation package would take for the same network.
