From the Seattle MMDI Evaluation Report: Section 3.3.1 ATMS Signal Integration Evaluation
Seattle, Washington, United States
The North Seattle Advanced Traffic Management System (ATMS) was enhanced to allow the integration of 19 metropolitan North Seattle, Washington, city signal systems. The enhancement also included interconnection with the Traffic Control Centers (TCCs) of nine cities, three transit agencies, and Washington State DOT's arterial signal and freeway ramp metering systems as well as the East and South Seattle ATMSs. The ATMS also collected regional traffic data including traffic volumes, occupancy, speeds, surveillance video/snapshots, incident information, and signal system status. The cost of customizing software applications to make them compatible with the communications system network backbone was a major driver in the cost of the system. In addition, the costs of installing traffic detection devices, computer work stations, and communications hardware equipment were significant.
The following table presented in the report provides additional detail on the North Seattle ATMS Cost Estimate.
