Project Details
AbstractThe focus of this research was to meet the growing need for accurate and practical methods to support traffic analysis in work zones. Road construction and maintenance activities have become a common feature for many U.S. roads over the last few years due to ageing infrastructure. This research examined the application of two classes of traffic analysis models, macroscopic sketch analysis (QuickZone) and microscopic traffic simulation (Dynasim and VISSIM), to evaluate the traffic impacts caused by work zone activities. The research evaluated the application of these tools to an urban interstate work zone. Specifically, this research examined the following: 1) how the use of traffic analysis models relates to federal requirements about considering traffic impacts of major construction projects, 2) the accuracy of model results in comparison to real-world conditions, and 3) modeling effort and data requirements of these models.
