This document presents an executive summary of a modeling analysis of Intelligent Transportation Systems (ITS) impacts from the SmartTrek program in Seattle, Washington. This report describes the methodology of the study and presents the finding for a mixed freeway/arterial corridor model drawn from the roadway network north of downtown Seattle. The areas studied included Advanced Traveler Information Systems (ATIS), Advanced Traffic Management Systems (ATMS), and Incident Management Systems (IMS). The impacts are placed in the following categories: near-term peak period delay reduction, travel time reliability, changes in regional mode choice, corridor travel throughput, fuel consumption, and emission rates. A specific feature of the study involved the quantification of likely impacts from data sharing or integrated control between three functional areas (ATIS ATMS, and IMS) and across jurisdictions. |
