Project Evaluation Program

The Denver Department of Transportation and Infrastructure (DOTI) Evaluation Initiative evaluates the effectiveness of projects to understand if they are having the desired impact towards achieving Denver’s transportation vision. Evaluation results are used to identify necessary changes to street design, prioritize future safety improvements, make data-driven decisions to install the most effective treatments, and gather community support for similar projects. The initiative gathers quantitative data (crashes, volumes, speeds, bikes+ ridership, etc.) and qualitative data (user comfort and perception) to build a comprehensive understanding of DOTI’s projects.

Ongoing Evaluations

Fall 2025/Winter 2026

DOTI is gathering quantitative and qualitative (survey) data to evaluate the following treatments:

  • RRFBs
  • Protected bike lanes
  • Conventional bike lanes
  • Speed cushions
  • Right-turn-on-red prohibitions
  • Speed limit signage density

 

Thank you to those who took the qualitative survey in Fall 2025. DOTI is processing and analyzing the data. Evaluation results will be available in Spring 2026.

 

Previous Evaluations

In 2025, DOTI completed the Vision Zero and Bikeways Evaluation Study, the first large-scale evaluation effort in DOTI's Project Evaluation Program. This study showed, among other insights, that our projects are helping to achieve our safety and mode shift goals. Some specific treatments worked better than others and DOTI is adjusting its planning, design, and construction practices to make our projects even more effective at increasing safety and mobility in Denver.
