As intelligent transportation systems (ITS) are increasingly used for addressing transportation problems, the need for reliable estimates of planning level costs grows. The ITS Deployment Analysis System (IDAS) is being developed by a team headed by Cambridge Systematics under the guidance of Oak Ridge National Laboratory as a sketch planning software tool designed to estimate the potential benefits and costs of ITS improvements. The IDAS model estimates costs by creating an automated inventory of ITS equipment necessary to deploy ITS improvements selected by the model user. The inventory of the types and quantities of equipment is used to drive the calculation of estimates of costs by year and average annual costs. The results can be used to quickly assess the feasibility of individual ITS improvements or combinations of improvements. This paper details the IDAS cost module data inputs, model procedures, and outputs. (A*)
