摘要：	People who live in urban area nationwide report that traffic congestion is one of their greatest quality-of-life concerns. When the demand for travel in a region exceeds the available capacity of the transportation system, residents suffer from excessive travel times, increased crash risks, diminished air quality, and other negative impacts. State and local transportation agencies have found it difficult to increase the transportation system supply rapidly enough to keep pace with the growing demand. Traditional approaches such as adding highway lanes, building new roads, or providing new transit lines are often too costly to be considered as reasonable solutions. Transportation agencies have increasingly turned to improved operational strategies and Intelligent Transportation Systems (ITS) in order to squeeze more operational efficiency out of the existing transportation system. Example of these operations and ITS strategies include synchronizing the timing of traffic signals to smooth traffic flow, providing incident response vehicles such as freeway service patrols to quickly clear traffic incidents and breakdowns, automatically tracking and dispatching transit buses to improve their on-time performance, and providing meaningful traveler information to the public to allow travelers to better plan their trips. The potential benefits and costs of fully deploying and integrating operations and ITS strategies in the Seattle region were examined in this analysis. A full Operations and ITS Deployment Scenario was identified, representing the maximum amount of locally desirable operations and ITS. This Full Deployment Scenario was compared to a scenario without any operations and ITS deployments in order to identify the incremental changes in impacts that might be possible in the year 2003. The results showed the investment in operations and ITS to be cost-efficient-returning $12.20 in benefits for every dollar invested.
