MnDOT Geometric Design Institute

The Institute features four three-day workshops that educate Minnesota transportation practitioners on the fundamentals of roadway design. Participants will use design theory, MnDOT standards, and equations to learn the fundamental principles of roadway design. Topics include performance-based practical design, horizontal alignment, vertical alignment, superelevation, quantities, earthwork, cross sections, and more. Participants will engage in hands-on group learning using layouts, scales, highway curves, and triangles.

Each workshop agenda is specialized and will emphasize just two or three topics. Participants may attend one or all workshops.

Workshop Dates, Location, and Details

Superelevation, Drainage, and Vertical Alignment

December 13-15, 2022
Day One: 9:00 a.m.–4:00 p.m. Central
Day Two: 8:00 a.m.–4:00 p.m. Central
Day Three: 8:00 a.m.–4:00 p.m. Central

MnDOT Shoreview Training and Conference Center
1900 County Road I West, Shoreview, MN 55126

This three-day workshop builds on the Fundamentals of Roadway Design and Horizontal Alignment Workshop by providing information on basic two-lane superelevation and shoulder applications. The workshop reviews several multi-lane and ramp applications and intersection considerations, drainage impacts from superelevation design, and spiral transition curves. Additionally, this workshop covers the geometry of vertical curves, standards and design considerations, vertical curve sight distance criteria and some related design challenges, interactions of vertical curvature, superelevation, and drainage.

Advanced Horizontal/Vertical Alignment and Intersection Applications

January 10-12, 2023
Day One: 9:00 a.m.–4:00 p.m. Central
Day Two: 8:00 a.m.–4:00 p.m. Central
Day Three: 8:00 a.m.–4:00 p.m. Central

Shoreview Community Center
4580 Victoria St N., Shoreview, MN 55126

This three-day workshop covers horizontal and vertical alignment with more advanced examples and challenges. Attendees learn how the three components of a road plan—plan, profile, and cross section—are integrated to account for intersections, drainage, sight distance, and quantities. Nearly every highway and street design effort involves some elements of intersections. The proper engineering of an intersection can be one of the most challenging tasks in road design. Topics involved in intersection design include general geometric parameters, alignment and grade considerations, intersection sight distance, design vehicle consideration, and pedestrian considerations and design.

NOTE: The Institute’s two other workshops—Fundamentals of Roadway Design and Horizontal Alignment and Typical Sections, Cross Sections, Roadway Design, Quantities, and Earthwork—were held earlier this year.

Registration

If you are a MnDOT employee, please follow these instructions to register:
