Abstract

There is meager evidence relating to the amount of diversion of traffic from highways with work zones and even less evidence of truck diversion.  This project will pull together whatever evidence exists, both theoretical and empirical, to assist work-zone traffic engineers with decisions about the expected amount of truck traffic that might be diverted from major highways to local streets.  The project will leverage two research projects currently being conducted at UWM.  The first ongoing project, being performed for the Smart Work Zone Deployment Initiative, is an analysis of vehicle diversion from two rural work zones on I-94 in Portage and Tomah.  The second project, being performed for WisDOT, is a similar analysis of an urban work zone on I-94 in Milwaukee.  In addition, UWM performed an analysis of the full freeway closure of I-894 in Milwaukee.

Objectives

Develop a synthesis of literature and empirical evidence of the level of truck diversion.

Tasks

  1. Review literature on truck diversion.
  2. Review case studies of truck diversion.
  3. Perform additional analysis of truck diversion data.
  4. Write working paper.
