Projects

Denver Central Business District - Traffic Signal Retiming

2019 | Denver, CO | City and County of Denver | Highways & Roads

A comprehensive data collection, modeling, and retiming project for over 200 intersections within the Denver Central Business District diagonal grid. The project addressed degraded operational performance, circulation changes from new bike lanes, and significant traffic volume growth. It maintained progression on numbered streets and major commuter corridors like Colfax and Broadway, while delivering significant improvements on named streets.
