Interstate 64 Traffic Response Assessment Study

This study evaluates the impacts of using traffic response patrols along the I-64 corridor in St. Louis, Missouri, during the two-year full closure of this corridor. A three-page executive summary of the findings from this study are included here. The Missouri Department of Transportation (MoDOT) reconstructed over 10 miles of roadway and 30 interchanges as part of this project, and it redirected traffic to arterials during the two full closures. MoDOT found a benefit-cost ratio of 8.3:1 associated with implementation of its arterial service patrol program and used performance measures to evaluate the success of this program. The study also offers recommendations for implementing traffic response patrols in other areas across the country.
