Nonrecurring congestion can occur at any location at any time and results in delay to motorists as well as a potential for subsequent traffic incidents. TSMO strategies should be utilized to address each type of nonrecurring congestion generator.

'''Construction '''

:* As an initial step, a project design should be selected to eliminate or minimize additional delays and traffic queueing during construction. [[616.13 Work Zone Capacity, Queue and Travel Delay|EPG 616.13 Work Zone Capacity, Queue and Travel Delay]] provides tools to access the traffic impact of the proposed project design(s).
:* Once a project design has been determined, the [[616.13 Work Zone Capacity, Queue and Travel Delay#MoDOT Work Zone Impact Analysis Spreadsheet|MoDOT Work Zone Impact Analysis Spreadsheet]] will assist in determining which smart work zones strategies should be included in the project to provide information and warnings to motorists to improve work zone safety and traffic mobility. Additionally, the [[media:909 WZM Guidebook.pdf|Work Zone Management Guidebook]] provides information about tools and strategies for work zone management that will maximize safety and minimize the impacts to traffic. The [[media:909 WZM Presentation.pdf|Work Zone Management Guidebook Presentation]] provides additional information about the guidebook. Additional information can also be found in [[616.13 Work Zone Capacity, Queue and Travel Delay|EPG 616.13 Work Zone Capacity, Queue and Travel Delay]] and [[616.14 Work Zone Safety and Mobility Policy|EPG 616.14 Work Zone Safety and Mobility Policy]].
:* When traffic incidents occur within a work zone, it is imperative to clear the incident and restore traffic as quickly as possible. To aid in this effort, a project-based traffic incident management (TIM) plan should be developed for all significant projects on interstate and freeways.

'''Traffic Incidents'''

Traffic incidents occur without warning at any time and location on the highway system. On all segments of the interstate and freeway highway system, traffic incident management (TIM) plans should be developed in coordination with law enforcement and local responders to:
:* Reduce response and clearance times
:* Develop alternate plans for handling affected traffic
:* Communicate and coordinate between responders
:* Communicate traffic impacts to motorists.

909.1 Recurring Congestion

New page

Highway segments with recurring congestion are candidates for highway improvements. While adding capacity by constructing additional lanes may not be feasible, other TSMO strategies should be considered as alternate solutions which are often more economical than traditional construction solutions. Strategies such as integrated corridor management (ICM), active transportation and demand management (ATDM), ramp metering, and lane management may provide substantial improvements to recurring congestion.

	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.~~		Transportation Systems Management and Operations (TSMO) consists of operational strategies and systems that cost-effectively optimize the safety, reliability, efficiency, and capacity of the transportation system. TSMO emphasizes maximizing the performance of the existing system through proactive management and operational improvements.

	~~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~~.
