The absence of systematic analysis of the societal benefits and costs of Intelligent Transportation Systems (ITS) technologies -- in the short-term as well as long term -- is well recognized in the ITS community. This unmet need has been recognized, for example, by the Benefits and Evaluations Committee of ITS America. As public policy makers look beyond the current International Surface Traffic Efficiency Act (ISTEA) authorization, the question of expected potential benefits from ITS technologies are sure to be raised by the congressional committees. Yet, the available information is quite dated and may not be adequate for presenting a compelling case. This working paper is an attempt to put the issue of models to evaluate potential ITS benefits in a programmatic perspective, so that groundwork is laid for future Federal Highway Administration (FHWA) efforts on the subject matter or modeling related projects. |
