Abstract:This report presents the test plan for conducting the Air Quality 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/event 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/events, 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 Air Quality Analysis Test Plan is
based on the ICM Initiative Demonstration National Evaluation Framework. This test plan provides an
overview of the Air Quality 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.
