Integrated corridor management initiative : demonstration phase evaluation - Dallas decision support system analysis test plan.

This report presents the test plan for conducting the Decision Support System (DSS) Analysis for the \nUnited States Department of Transportation (U.S. DOT) evaluation of the Dallas U.S. 75 Integrated \nCorridor Management (ICM) Initiative Demonstration. The ICM projects being deployed in Dallas \ninclude a suite of strategies aimed at balancing U.S. 75 corridor transportation supply and demand to \npromote overall corridor efficiency and safety. Operational strategies to be deployed in the Dallas \nU.S. 75 highway corridor include: simulations to predict travel conditions for improved incident \nresponse, interdependent response plans among agencies, traffic diversion to frontage roads and \nstrategic arterials, traveler mode shift to the light rail system during major freeway incidents, and \ncomparative travel time information to the public and operating agencies for freeway, HOV lanes, \nfrontage roads, arterial streets, and light-rail transit lane. Technologies that will be used to carry out \nthese strategies include a Decision Support System, a 511 traveler information system (telephone and \nwebsite), a regional center-to-center information exchange network, dynamic message signs, parking \nmanagement systems, transit signal priority and responsive traffic signals. This DSS Analysis Test Plan \nis based on the ICM Initiative Demonstration National Evaluation Framework. This test plan provides \nan overview of the DSS Analysis and describes the specific qualitative and quantitative data that will be \ncollected to support the analysis. Data analysis methodologies as well as risks and mitigations \nassociated with this evaluation analysis are also discussed in this test plan. \n
