Develop Annual Arterial Congestion Report

Principal Investigator(s):

Henry Liu, Former Professor, Civil, Environmental and Geo-Engineering

Project summary:

Since 1993, the Minnesota Department of Transportation (MnDOT) has prepared an annual Metro Freeway System Congestion Report that documents congested segments of the freeway system. The report not only measures freeway system performance but also helps MnDOT identify freeway segments that are over capacity, and prioritize and allocate the available resources for project planning. However, a similar congestion report for the arterial system has not been developed, although signalized arterial roads carry a large percentage of traffic in the Twin Cities metropolitan area. This is primarily due to the lack of a way to automatically collect traffic signal data and measure performance. In practice, the need to manually collect the data and then calculate performance metrics for an intersection or an arterial has made performance assessment a time-consuming and expensive process for MnDOT. This project aims to develop an annual congestion report for Twin Cities arterials.
