Office of PolicyUS Transportation CollectionIntelligent Transportation Systems (ITS) have generated considerable enthusiasm in thetransportation community as a potential strategy for reducing highway congestion, improvinghighway safety, enhancing the mobility of people and goods, promoting economic productivity,and reducing the environmental impacts associated with motor vehicle travel. However, as stateand local governments across the country proceed with the deployment of ITS services andtechnologies, some policy makers are concerned that the detrimental emission effects ofincreasing the number of vehicle trips and miles traveled may partially offset the potentialemission benefits of improved traffic operations and system efficiencies. The objective of thisstudy is to describe the types of modeling approaches needed to capture the short- and long-termtransportation and emission/fuel consumption impacts of ITS deployment
