San Antonio's Medical Center Corridor. Lessons Learned from the MetropolitanModel Deployment Initiative. Reducing Delay through Integrated Freeway and Arterial Management

摘要

This report demonstrates the benefits and potential pitfalls of deploying andoperating an integrated freeway and arterial management system. In particular, it discusses the lessons learned associated with the Medical Center Corridor Project deployed in San Antonio, Texas, in concert with the Metropolitan Model Deployment Initiative (MMDI). As one of four sites participating in the MMDI effort, San Antonio was committed to pursuing integrated deployments of Intelligent Transportation Systems (ITS). One of the goals of deploying these integrated systems was to develop more effective, coordinated management of roadway incidents and their associated delays. In San Antonio, this was accomplished through integrating the region's highly successful freeway management system with a newly developed and deployed arterial management system in the city's north end. This report details the lessons learned from this deployment and describes how, with careful implementation and operation, an integrated freeway/arterial management system can lead to significant reductions in delay, crash risk, and fuel consumption.
