About Program Support
What we do
Traffic Engineering's primary responsibility is to provide initial contact to area personnel to aid them in making the proper design or operational decisions as it applies to traffic, road design or volume capacity. We review various documents which require traffic comments or analysis.
The Program Support Engineer signs all geometric layouts on behalf of Metro Traffic Engineering.
Program support is divided into four areas. This map shows how the Metro District is divided, which roadways are in each area and contact information for each area.
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.
- Office of Traffic, Safety,and Technology (OTST) - Provides further resources and publications regarding speed limits.

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.

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.
Key Contact - David Sheen - (651) 234-7824
Detailed Intersection Control Evaluation information:
- Intersection Control Evaluation (ICE) Report - 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. The manual is in a pdf format and is provided by the Office of Traffic, Safety, and Technology.
- Signal Design Tools - The Office of Traffic, Safety and Technology 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
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:
- Office of Traffic, Safety, and Technology (OTST) Provides further resources and publications regarding crash analysis.
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.
Key contact- David Sheen (651)234-7824
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.
Detailed tort claims information:
- Attorney General Office – Access the Attorney General Website for further resources and information.
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.
Key contact- Gayle Gedstad - (651) 234-7815
Detailed HSIP/Safety program information:
- Highway Safety Improvement Program - Metro Criteria 2013 - 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.
- Office of Traffic, Safety, and Technology (OTST) will provide further resources and publications regarding HSIP/Safety Programs.
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.
