About this Project
Brief Project Description & Background
The proposed project involves the evaluation of the ITS deployments in a major metropolitan area in Missouri. Either the Gateway Guide or the KC Scout programs will be an ideal location for this effort. The results will be able to influence similar ITS programs and deployments regionally and nationally.
In this project, the PIs propose to evaluate the synergistic effect of several ITS deployments of a Traffic Management Center (TMC) on safety and operations. ITS deployments such as CCTV, DMS, Motorist Assist, and traffic detectors will be evaluated.
Evaluating the benefits of ITS deployments is relevant to four of the five USDOT and MATC's thematic topics: enhancing safety, economic competitiveness, environmental sustainability, and livable communities. The ITS deployments evaluated in the project are intended to improve incident management (IM) through faster detection, response, clearance, of incidents and quicker recovery of roadway capacity. Efficient incident management results in, 1) safety benefits in terms of reduction in secondary accidents, 2) economic benefits in terms of improved travel time reliability and lower travel times, 3) lower environmental impacts due to a reduction in the emissions and fuel consumption, and 4) better quality of life for communities through lower congestion, better air quality, and improved safety.
The Missouri Department of Transportation (MoDOT) has invested millions of dollars in ITS deployments over the last decade to improve the efficiency and safety of the transportation system. Some of these deployments have been evaluated by MoDOT. For example, University of Missouri-Columbia (MU) conducted research on evaluating the benefits of Motorist Assist program of Gateway Guide in St. Louis and the Dynamic Message Sign deployments in rural southeast Missouri. Although, there have been a few a la carte studies evaluating the benefits of individual components, there has not been a study that assessed the benefits of ITS programs such as incident management as a whole. The synergistic effects of the individual components such as CCTV, detectors, DMS, Motorist Assist and media tie-in will be evaluated and documented. The amount of MoDOT traffic and incident data along with crash data provides a great opportunity to conduct a data-driven evaluation of the ITS deployments. Unlike the planning-level models such as IDAS, such a data-driven evaluation does not require numerous assumptions about traffic behavior and therefore produces more accurate results. The research team plans to use actual before ITS deployment data that they collected in a previous project. The data was collected in St. Louis and Kansas City (KC) areas. The proposed project involves the evaluation of the ITS deployments the ITS program in a major metropolitan area in Missouri. Either the Gateway Guide or the KC Scout programs will be an ideal location for this effort. The results will be able to influence similar ITS programs and deployments regionally and nationally.
