This report describes the results of a major data gathering effort to track deployment of components of the metropolitan Intelligent Transportation Systems (ITS) infrastructure in 78 of the largest metropolitan areas in the nation. Data are included that describe: Freeway Management, Incident Management, Traffic Signal Control, Electronic Toll Collection, Electronic Fare Payment, Transit Management, Highway-Rail Intersections, Emergency Management, and Regional Multimodal Traveler Information. Deployment is tracked through the use of indicators tied to the major functions of each component. In addition, integration of components is being tracked by examining the transfer of information between components and the use of that information once transferred. The report summarizes results at a national level and includes information on the number of metropolitan areas deploying selected technologies related to the indicators. |
