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