Stakeholders implementing intelligent transportation systems (ITS) often have different goals, needs, and concerns that they intend their project to address. Consequently the development of a generic evaluation plan is difficult to develop. While it is recognized that the U.S. Department of Transportation has developed guidelines to aid agencies in evaluating such investments, this research is intended to complement these guidelines by assisting in the evaluation of a site specific ITS investment. This paper presents an evaluation framework that provides a systematic method for assessing the potential impacts associated with the project by defining objectives and measures that should be used for evaluation. In developing the evaluation framework, both qualitative and quantitative objectives and measures are defined. The objectives include factors such as service reliability, service efficiency, and customer satisfaction. The framework developed specifically addresses the ITS investment on the OmniLink local route deviation bus service in Prince William County, Virginia, but could be used as a basis for the evaluation of similar ITS investments. The OmniLink ITS investment includes an automatic vehicle location (AVL) system, mobile data terminals (MDTs), and computer-aided dispatch (CAD) technology.
