Abstract:This report provides an analytical framework for evaluating the two field deployments under the United States
Department of Transportation (U.S. DOT) Integrated Corridor Management (ICM) Initiative Demonstration
Phase. The San Diego Interstate 15 corridor deployers and the Dallas U.S. 75 corridor deployers are
implementing a suite of strategies aimed at balancing corridor transportation supply and demand to promote
overall corridor efficiency and safety. The strategies include decision support systems to aid transportation
operators in synthesizing incoming transportation system data and to develop, select and modify response plans; center-to-center information sharing and distribution strategies to promote coordinated, multi-modal and multi-agency responses; traffic signal timing adjustments and short-term transit capacity additions; and enhanced pre-trip and en-route traveler information to shift travelers to alternative modes or routes or to postpone trips to less
congested periods. The evaluation will investigate and document the investments made by both sites, including
ICM-related changes in policies and procedures; document and evaluate the capabilities acquired through ICM
deployment and how those capabilities were utilized; and assess the impacts of the deployments, including
mobility, safety, air quality and overall benefit-cost. Institutional and organization issues and lessons learned will
also be investigated. The evaluation features eight individual analyses focusing on specific ICM capabilities and
types of impacts.
