Project Overview
The Speed Limit Setting and Signing Project (SLSSP) will develop a consistent framework for establishing and communicating speed limits citywide. The project aims to help reduce speed-related crashes as part of Vision Zero, Boulder’s goal to end severe crashes.
Speeding has been identified by Boulder community members as one of the top traffic safety concerns on city streets, with speeding being an over-represented factor contributing to serious injury and fatal crashes. The project began directly from the recommendations, goals and objectives of the Transportation Master Plan and the Vision Zero Action Plan, a plan with prioritized actions the city will take to end serious injury and fatal crashes on our streets.
The project will study speed limits and signing primarily on arterial and collector roads, which are key roads that connect the city and often have higher speed limits. This study does not include local residential streets as these streets have a 20 mph speed limit as part of a city effort completed in 2020.
Goals
The project will improve the consistency and methodology behind citywide speed limit setting and signing by:
- Developing a quantitative citywide approach and practice for speed limit implementation methodology
- Creating a methodology document and sharing with the community and stakeholders
