The two main objectives of this multi-year program are to: 1) monitor freeway performance and analyze trends in traffic congestion and travel reliability using archived traffic operations data; and, 2) provide “proof of concept” and technical assistance to foster local/regional performance monitoring programs and the supporting data collection and archives. The FHWA-funded project has been ongoing since 2000, and has evolved in the past ten years. The current reporting structure is a quarterly national report that focuses on the most readily-available data in 23 cities (http://www.ops.fhwa.dot.gov/perf_measurement/ucr/). The results of this program are used by FHWA in their agency performance reporting processes, as well as in gaining a better understanding of the impacts and source of traffic congestion. Numerous state and local agencies have used the results and reports from this program to develop their own customized congestion reporting process within their agencies.
