In 1991, the Intermodal Surface Transportation Efficiency Act (ISTEA) required metropolitan planning organizations in Transportation Management Areas (TMAs) to implement a Congestion Management System (CMS). An urbanized area is designated a TMA when its population exceeds 200,000. The results of the 2000 decennial census indicated that the population of the urbanized area in Northern Ada County was 272,625. Therefore, on July 8, 2002 the Federal Highway Administration officially designated the urbanized area in Northern Ada County as a TMA. The Treasure Valley CMS Plan can be found at the link below.

In addition, the results from other annual data collection efforts are also available. The annual system progress reports can be found below.

If you have any questions regarding the CMS Plan or Annual Report, contact MaryAnn Waldinger at 475-2242.

The CMS travel time data set used to create the Annual CMS Reports is available below for the years 2003 through 2008. The data set contains the higher of the AM or PM peak travel time averages for each sampled roadway segment.
