Abstract:This report presents the test plan for conducting the Institutional and Organizational 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 Institutional and
Organizational Data Test Plan is based on the ICM Initiative Demonstration National Evaluation
Framework. This test plan provides an overview of the Institutional and Organizational 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.
