摘要：	As intelligent transportation systems (ITS) become mainstreamed into improvements tool kits, the ability to assess the relative costs and benefits of alternative ITS improvement strategies is critical. It is for this reason that the ITS Deployment Analysis System (IDAS) has been developed as a tool to assist transportation planners and others in the transportation arena. The transportation planning community has been using travel demand forecasting models to study alternatives for many years. To forecast travel demand, the traditional four-step modeling approach, which comprises trip generation, trip distribution, mode choice, and traffic assignment, is applied. In general, the IDAS software is designed to pick up where the traditional four-step planning models end. In fact, IDAS takes the output from four-step planning models to establish a base-case scenario. The IDAS user then selects from a list of ITS components and deploys one or more ITS improvements into the base case. IDAS executes its own travel demand model to determine the new travel patterns that emerge as a result of the ITS improvements. The incremental costs and benefits resulting from the deployment of the ITS components are then compared with the base-case scenario and presented to the IDAS user.
