Benefits and Costs from the Caltrans IRIS Open Traffic Management System Demonstration Study

Providing a well-managed transportation infrastructure is an essential function of a public transportation agency. Intelligent Transportation System (ITS) applications such as Advanced Traffic Management Systems (ATMS) improve safety and fuel efficiency, and reduce congestion. However, the software life-cycle costs of these systems often place them beyond the reach of small and medium-sized agencies. This paper discusses the results of the first implementation of the Intelligent Roadway Information System (IRIS) open ATMS outside of Minnesota. The California Department of Transportation (Caltrans) IRIS demonstration study implemented IRIS within a midsized urban/rural Caltrans district and two rural districts that otherwise could not afford an ATMS. Results show dramatic cost savings compared with an existing proprietary ATMS system, increased capabilities and reliability, and a number of secondary benefits derived from this multi-agency collaborative approach.
