TMD undertook Phase I of the Bus Corridor Master Plan that included a multiphase screening of transit system network segments using a variety of market, ridership, service, and operations criteria to identify a network of bus corridors that will receive major infrastructure improvements to right-of-way, signal priority, stations, and pedestrian and bike ways. These corridors will also be candidates for community initiatives in sustainable development and public space improvement. In Phase II, TMD worked with RTD to finalize the top corridors for enhancement and worked with the cities of Denver, Boulder, and Aurora to develop transit priority strategies for immediate-term implementation of the upgrades which covered the range of BRT toolbox options.
