Research helps field engineers manage traffic at work zones
When driversencounter a work zone, they have a choice: go through or go around. But for traffic engineers, this choice represents a tricky problem. How do you predict the number of drivers who will divert around the work zone versus the number that will go through, in order to create an effective traffic management plan?
“The capability to accurately estimate the traffic diversion caused by work-zone delays and the capacity reduction associated with lane closures is of critical importance in developing effect traffic management plans,” says Eil Kwon, professor at the Department of Civil Engineering at the University of Minnesota Duluth (UMD), the principal investigator of this study. “However, the traffic planning models that had been used to
