The Congestion Management Process (CMP) monitors the transportation network to determine the locations and sources of congestion in the Boston MPO area, and identifies and implements strategies that alleviate congestion. The Boston Region MPO´s CMP monitors the performance of the following types of transportation facilities in the MPO area:
- Freeway and arterial roadways
- Park-and-ride lots
- High-occupancy-vehicle (HOV) lanes, and
- Bicycle and pedestrian facilities
About the CMP
CMP monitoring leads to recommendations for studies to be programmed in the Unified Planning Work Program (UPWP) and for improvements to be implemented through the Transportation Improvement Program (TIP) and Long-Range Transportation Plan (LRTP). Federal legislation requires that, in metropolitan areas that do not meet the national ambient air quality standards, capacity-increasing projects for single-occupant vehicles be part of an approved CMP.
In 2012, the MPO established a congestion management committee to ensure that the appropriate congestion mitigation strategies are evaluated and promoted for funding in the UPWP, TIP, and LRTP.
2015 Express-Highway and Arterial Roadway Performance Dashboards
The Express-Highway Performance Dashboard and Arterial Performance Dashboard graphically display peak-period congestion for expressways and arterials in the Boston Region MPO area, in 2015. The performance measures in the dashboards represent three factors related to congestion: duration, intensity, and travel time reliability. Each dashboard consists of regional overview maps, route-specific data, and downloadable accessible tables. The data used in both dashboards were collected in 2015 by INRIX and processed by CTPS staff.
2012-2015 Expressway Comparator Application
The 2012–2015 Comparator Application compares performance measures such as average speed, speed index, and others between the 2012 and 2015 INRIX datasets. The applications include a map, bar chart, and line graph display of the 2012 and 2015 performance measures for each corridor. The comparator application is currently only available for limited access roadways.
