TSM&O STRATEGIES

Source: FHWA Operations Benefit / Cost Analysis Desk Reference, 2012

Definition: “Transportation System Management & Operations (TSM&O) is a group of strategies to optimize the performance of existing infrastructure through the implementation of specific systems and services that preserve capacity and improve reliability and safety.”

Commonly Used Measures of Effectiveness (MOEs)a. User travel time savings (mobility)b. User vehicle operating costs (VOC)c. Crashes (safety)d. Emissions e. Travel time reliability (reliability)

ARTERIAL SIGNAL COORDINATION (ASC) IN TOPS-EIA

Preset Timing

Traffic Actuated

Central Control

These signals have a preset cycle length for specified times of the day or for the entire day.

These signals can vary their cycle length to the traffic flow that uses the intersection.

These signals are controlled and directed by a central computer. Each intersection requires a standard controller and communication link to the central computer.
