What are Road Diets?

Undivided roadways often experience a large number of crashes–especially between high-speed through traffic, left-turning vehicles, and other road users. One treatment for addressing this safety concern is a Road Diet, which typically involves removing or narrowing motor vehicle lanes and utilizing the space for other uses, including but not limited to a two-way left-turn lane (TWLTL), non-motorized travel modes, or parking.

Workshop Agenda

Part 1:

  • Why consider a Road Diet?
  • When to use a Road Diet?
  • How to design a Road Diet?

Part 2:

  • Evaluate a real-world Road Diet candidate project.
  • Document findings and make recommendations.
