 The Transportation Systems Management (TSM) approach to congestion mitigation seeks to identify improvements to new and existing facilities of an operational nature. These techniques are designed to improve traffic flow and safety through better management and operation of existing transportation facilities. Transportation systems management strategies include intersection improvements and signalization improvements, a freeway bottleneck removal program, and special events management strategies. These strategies are developed to reduce travel time and enhance system accessibility.
Intersection improvements, such as turning lanes, grade separations, pavement striping, signage and lighting, bus turnouts, and channelization of traffic, can greatly improve traffic flow operation on arterials and at intersections. Traffic signal enhancements include signal timing optimization, signal equipment upgrades, and system interconnection. Freeway and arterial bottleneck removal consist of improving insufficient acceleration and deceleration lanes and ramps, sharp horizontal and vertical curves, narrow lanes and shoulders, inadequate signage and pavement striping, and other geometric characteristics. The identification and elimination of traffic bottlenecks can greatly improve traveling conditions and safety, especially during peak periods. TSM projects can complement the major capacity improvements and infrastructure by providing improved traffic flow on arterials and local streets.
NCTCOG's Current TSM Project :
Traffic Signal Integration and Monitoring Program, Phase 2.1
The purpose of this program is to audit of selected thoroughfares, assessment of operational characteristics, estimation of air quality benefits, and the development and implementation of recommended improvements.
The goal of the program is to maximize capacity of our existing system by implementing low cost capital improvements on selected thoroughfares.
This project is divided into three areas: 1) a detailed traffic delay and air quality before/after analysis, 2) thoroughfare assessment, and 3) survey of vehicle detectors associated with traffic signals.
