Category:909 Transportation Systems Management and Operations (TSMO)

Transportation Systems Management and Operations (TSMO) consists of operational strategies and systems that cost-effectively help optimize the safety, reliability, and capacity of the transportation system. MoDOT is continuously working to improve safety and alleviate congestion on its roadways; the effective application of TSMO strategies will help to further improve MoDOT’s roadways by directly addressing many of the root causes of recurring and nonrecurring congestion.

Recurring congestion occurs in numerous locations in the interstate and state highway system and is typically the result of inadequate capacity of the existing highway facilities. Recurring congestion occurs most often during peak traffic periods. MoDOT is not funded to construct sufficient highway facilities to address all areas of recurring congestion.

Nonrecurring congestion occurs throughout the interstate and state highway system at any given time and is typically the result of:

• Work Zones (road construction and maintenance activities, permit work, etc.)
• Traffic Incidents
• Special Events.

Recurring and nonrecurring congestion both result in delay to motorists, adversely affect travel time reliability, and diminish highway safety. MoDOT is committed to integrating TSMO in all aspects of managing and operating the transportation system in Missouri.
