Workshops on Dynamic ATM Strategy Selection Tool (FREEVAL-DSS)

According to the latest Urban Mobility Report, United States urban motorists in 2011 traveled an additional 5.5 billion hours and purchased an extra 2.9 billion gallons of fuel as a result of congestion. The economic impact of degraded mobility has been estimated at $21 billion, which is quickly eroding the nation’s economic competitiveness. The Federal Highway Administration estimates that about half of all congestion delays are caused by non-recurrent congestion events, including incidents, weather, work zones, demand surges and inadequate base capacity. Yet methods for assessing the effectiveness of active traffic management (ATM) strategies aimed at improving mobility are still rooted at a planning level approach rather than the operational levels of implementation. This research has intended to develop efficient methods that dynamically evaluate the current traffic system performance, propose interventions that can ameliorate the performance as needed, and implement and re-evaluate the effectiveness of the intervention. The research team has developed methods and a computerized tool (FREEVAL-DSS) that will propose and implement near real time active traffic management strategies on simulated freeway facilities. In a way, what the tool does is create a virtual (simulation) lab for assessing ATM methods in the same fashion they would be considered, evaluated and implemented in a freeway traffic management center (TMC), that is: observe conditions, diagnose problem, propose solution, implement solution, observe, and so on. FREEVAL-DSS allows assessing alternative improvement strategies before actual implementation in their operations. In addition, it will add to the knowledge based on the development of real-time decision support systems at traffic management centers. The utilization of a macroscopic rather than a microscopic simulation model as a basis for the development will ensure an efficient use, calibration, and implementation of the developed environment. The research team is proposing conducting a hands-on workshop on findings of STRIDE 2013-009S project and primarily FREEVAL-DSS tool. This will be the first workshop on disseminating the outcomes and findings of STRIDE project 2013-009S. The project team may propose to hold another workshop based on future opportunities. The objective of this project is to conduct workshops on FREEVALDSS tool. The workshops will be offered with all necessary perquisite materials that users need to know in order to work with the FREEVAL-DSS tool. The project team is intended to hold the workshop at Southeastern Transportation Research, Innovation, Development and Education Center (STRIDE) conference in Knoxville, TN; Chicago, IL; Florida and California.
