CHART Incident Response Evaluation: Final Report
Summary Information
The Maryland Coordinated Highways Action Response Team (CHART) program is in the process of expanding to more automated surveillance with lane sensors and video cameras. The evaluation of the initial operation of the program shows a benefit-to-cost ratio of 5.6:1, with most of the benefits resulting from a 5 percent (2 million vehicle-hours per year) decrease in delay associated with non-recurrent congestion.
