Congestion Management Process

Congestion Management Process

The Congestion Management Process (CMP; previously called the Congestion Management System) is a systematic approach for collecting data and identifying congested transportation facilities with the intent of developing appropriate mitigation measures.

The Treasure Valley Congestion Management System Plan outlines congestion management elements, the travel time data collection process, use of the data, specific definitions for congestion, and a “toolbox” of mitigation strategies.

From 2003 – 2015, COMPASS annually collected travel time data to quantify and identify trends in roadway congestion to help transportation and land use planning entities implement congestion management strategies and projects to improve travel time, particularly in areas of “high” congestion.

Beginning in 2018, COMPASS will report travel time for I-84 and select state highways using data available as part of the National Performance Management Research Data Set (NPMRDS). The coverage is much less than locally collected travel times, but the time data are more comprehensive (24 hours per day; 7 days per week). This will allow staff to analyze how travel times vary by season, time of day, and days of the week, and analyze how fast the system recovers after an incident. 

Transportation system management and operations involve multi-modal transportation and emergency management agencies, and include planning and implementation of ITS (Intelligent Transportation Systems) and the I-84/I-184 detours online interactive map.
