About Program Support

What we do

Program Support's primary responsibility is to provide traffic engineering, capacity, and safety analysis for the planning and development of all Metro projects; Identify and program traffic safety and capacity projects; Investigate and respond to all traffic safety concerns or requests for info from the public, legislators, media, cities and counties; Investigate and prepare responses to tort claims and law suits against MnDOT; Perform freeway traffic modeling; Conduct speed studies on all roads to determine a safe and reasonable speed limit; Review externally submitted documents (permits, layouts, environmental documents, corridor studies, etc.) and assure traffic engineering safety and mobility issues are addressed.

Program Support is divided into four areas. Please see the TSAM map (PDF) for Metro District Traffic area contacts.

Other Responsibilities

Before and after studies

Evaluates crash occurrence 3 years before and 3 years after a safety project to determine the crash rate reduction and the benefit/cost ratio. This will measure our effectiveness in constructing the project and will guide us in future funding decisions. 

Crash Analysis

Crash data is used to make planning, programming, design, and maintenance decisions. Data is also used for tort claim investigations, insurance claims, lawsuits, cooperative agreement and HSIP submittals, and to provide information to the media and the general public.

Detailed crash analysis information:

Freeway Analysis

Primary responsibilities include applying state of the practice solutions, research and performance measures to freeway mobility and safety problems. This includes reviewing layouts, interstate access modification requests and traffic reports, and developing low cost high benefit solutions to congested and crash prone areas of the freeways in the Twin Cities.

Freeway/Arterial Modeling

Freeway Modeling provides services for evaluation of interchange and mainline design alternatives; reviews Interstate Access Requests statewide; assesses freeway modeling packages; provides training to consultants; and reviews traffic studies. 

Detailed freeway/arterial modeling information:

HSIP/Safety Program

Investigates crash problem locations and determines appropriate remedial measures, develops concept plans, determines cost estimates and program projects for construction. Evaluates crash data through the use of various prioritized lists to determine safety problems.

Detailed HSIP/Safety program information:
  • Highway Safety Improvement Program - Metro Criteria 2020 (PDF) - This document explains the requirements and gives guidance for the Highway Safety Improvement Program (HSIP) to applicants desiring to obtain federal funds under the Federal MAP-21 legislation. Document includes, introduction, qualifying criteria, prioritization criteria, required material and special instructions, MnDOT contacts, HSIP timeline flowchart, narrow shoulder paving guidelines, HSIP application form, and project information form.

Intersection Control Evaluation (ICE) reports

The purpose of an Intersection Control Evaluation (ICE) report is to document if a traffic control change is justified and what the new intersection traffic control should be. 

Detailed Intersection Control Evaluation information:
  • Intersection Control Evaluation (ICE) Report (PDF) - A pdf file which clarifies the requirements and standardization of submittals for Metro District intersection control evaluation (ICE) reports. This document includes a sample signature sheet and outline for an ICE.
  • Signal Design Manual - The purpose of this manual is to present the fundamental concepts and standard practices related to the design of traffic signals systems within the State of Minnesota. This manual is structured to parallel the progression of decisions, activities and functions related to the design of traffic signal systems.
  • Signal Design Tools - The Office of Traffic, Safety Engineering maintains various design tools for the process of standardizing the plan design and construction process for signals, lighting, signing, markings, work zone control, and other traffic related aspects of roadway design and operation.
  • Roundabout Information

Speed Zoning

Conducts engineering and traffic investigations to determine reasonable and safe speed limits for all roads (state, county, city, and township) within the eight county Metro District; and recommends speed limits for authorization by the State Traffic Engineer.

Detailed speed zoning information:

Tort Claims

Deals with civil suits (not criminal) where someone claims damage or injury caused willfully or by our negligence in performing or not performing our duty/work. 

The criteria for a claim are divided into two definitions:

  • Self Insured - The Department of Administration contracts with a private company to manage all operational claims. Operational claims involve any moving MnDOT vehicle or mobile operation (including snowplows, paint crews, lawnmowers, etc.) that results in property damage.
  • Attorney General - The Attorney General Office handles all law suits and non-operational claims. Non-operational claims involve property damage caused by potholes, debris, contractors, construction zones, etc.
