Benefits and Costs of Full Operations and ITS Deployment. A 2003 Simulation for Cincinnati. Varying Weather and Work Zone Conditions

摘要

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. Examples 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. This analysis examined the potential benefits and costs of fully deploying and integrating operations and ITS strategies in the Cincinnati region. 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 $11.80 in benefits for every dollar invested.
