| Abstract | To help transportation planners in quantifying the benefits of ITS deployments, the Federal Highway Administration (FHWA) has recently sponsored the development of a sketch planning analysis tool for estimating the benefits and costs of ITS deployment called the ITS Deployment Analysis System (IDAS). IDAS, which was developed by Cambridge Systematics for the FHWA, operates as a post-processor to traditional planning models based on the four-step planning process. The current paper describes a study that used IDAS to predict the likely benefits of deploying ITS in Chittenden County, Vermont, a medium-sized region located in the northwestern part of the State of Vermont. A sensitivity analysis was also conducted to assess the sensitivity of IDAS’ results to the choice of values of some of the model’s parameters. The paper provides some insight into the applicability of using IDAS to evaluate the benefits of ITS deployments in medium-sized areas. Moreover, the sensitivity analysis conducted demonstrates that some of the model’s parameters tend to have a more significant impact on the results than others. Finally, the results indicate that, for medium-sized areas similar to Chittenden County, signal coordination along major arterials and transit AVL and scheduling projects appear to be more cost-effective than freeway and incident management systems. |
