Abstract

Intelligent transportation systems (ITS) can include multiple technologies and applications to improve the efficiency and effectiveness of a transportation system or network. These applications are deployed with the hope of achieving the goals and objectives of multiple stakeholders. This research includes a methodology to evaluate large-scale ITS infrastructure projects using the I-91 ITS project as a case study. The methodology includes a literature review; a clear definition of project goals, objectives, and intended outcomes; development of hypotheses for project outcomes; specific measures of effectiveness; data-collection methods; and criteria to measure the success of achieving the objective. The I-91 ITS project team should consider the following recommendations as next steps in conducting an ITS evaluation: identify and prioritize the goals and objectives, develop a multiphase evaluation approach, identify existing sources of predeployment data, identify missing data requirements, and document the existing communication protocol before deployment. Such a large-scale evaluation requires extensive effort, and priority should be given to developing a multiphase approach. This research may be used to develop an evaluation plan, which is recommended as a component of the six-step process outlined in the evaluation guidelines from the U.S. Department of Transportation.
