Innovative Bike Facility Evaluation
The District of Columbia District Department of Transportation (DDOT) has implemented several innovative bicycle facilities intended to improve cyclist comfort and safety by reducing cyclist-motorist conflicts. KAI led a comprehensive analysis of these facilities to evaluate their impact on safety and operations for all modes. The evaluation included before and after video data analysis of conflicts, multimodal level of service analysis, and user surveys on three facilities within the District. These facilities include cycle tracks, bike boxes, bicycle signal heads, and contra-flow bike lanes. The evaluation provided a unique opportunity to assess these innovative facilities from the perspective of all roadway users to understand both their benefits and drawbacks. The results of the evaluation will be used to refine the existing designs, as well as to provide guidance on best practices to achieve desired results for future bicycle facility designs within the District.
