Development of a Traffic Management Decision Support Tool (DST) for Freeway Incident Traffic Management (FITM) Plan Deployment – Phase 2: An enhanced DST-I95, including I495, I695, I70, US29

As a part of phase 1 (MD-17- SHA/UM/4-19), research was conducted in Fiscal Year 2016 for I-95 to develop a multi-criteria decision support tool for estimating incident-incurred delay and queue length for non-recurring congestion. Prior to this research, and due to the lack of statistical analyses on all the factors that affect an incident duration, CHART operations relied on their personal knowledge and experience to arrive at a conclusion on whether it is beneficial to deploy a FITM detour plan. Since its development, operators have extensively used the decision support tool to make operations decisions for I-95. Unfortunately, validation of the historical incident data using the decision support tool’s traffic flow modules was limited to I-95 only. The proposed research will leverage the recently developed statistical, traffic-flow, cost effectiveness, and artificial learning modules to expand the project limits to other corridors of interest, especially the I-695, I-70 and US-29. The expanded geographic coverage would lead to better operations and incident management across the state of Maryland. The Maryland Department of Transportation State Highway Administration (MDOT SHA) will be able to use the data-driven results from this study to make well-informed decisions when deploying FITM plans along major highways in the State. Better and faster decision-making will help reduce traffic delays as well as user costs, which can be extensive when they are caused by a major traffic incident/event.
