Abstract:At the request of the Joint Program Office (JPO) for Intelligent Transportation Systems (ITS) of the Federal Highway Administration (FHWA), Mitretek Systems has conducted a modeling
analysis of ITS impacts in support of the Metropolitan Model Deployment Initiative (MMDI)
evaluation program. The Mitretek modeling effort supports the evaluation of the Seattle model
deployment, Smart Trek, through impact analysis in the areas of Advanced Traveler Information
Services (ATIS), Advanced Traffic Management Systems (ATMS), and Incident Management Systems (IMS). Of particular interest to this modeling study (as well as the overall MMDI effort) is the quantification of likely impacts from data sharing or integrated control between functional areas (ATIS, ATMS, and IMS) and across jurisdictions. This document presents the methodology of the study and details findings for a mixed freeway/arterial corridor model drawn from the roadway network north of downtown Seattle. Impacts are characterized in terms of near-term peak period delay reduction, travel time reliability, changes in regional mode choice, corridor travel throughput, fuel consumption, emission rates, and other measures.
