'After the project was installed, all roadway crashes along the corridor decreased by 46 percent, and bicycle injury crashes decreased by 91 percent, according to the study. The DDOT spokesperson called those statistics “a tremendous testament” to the safety impact of protected bike lanes.
The 15th Street bikes lanes also improved the flow of traffic. After the project was installed, speeds increased by 17 percent, with peak northbound travel time decreasing by 36 seconds and peak southbound travel time decreasing by 40 seconds on the corridor, according to the study.
“This project is doing all the right things,” Krumpos said. “The data shows that the project is working and that there is not a negative impact for people driving.”'
