The existing, dedicated bus rapid transit (brt) routes should be made accessible and safe to pedestrians and cyclists.
They could also be used for restricted access to motorists during high traffic times and/or events.
Pittsburgh is a very unique city with regard to its construction and geography. A lot of the busy neighborhoods are clogged with cars and cyclists during high traffic times and it can become really inconvenient and even unsafe. Meanwhile, BRT roads already exist and take up so much real estate that could be more effectively utilized. Perhaps there can be hours during which they are restricted and other hours during which they are flexible for other purposes. Maybe they can be extended to have a section for cyclists. I also think there is potential for the BRT roads to be used for autonomous vehicle testing and research that will eventually encourage investment and reduced liability for the city.
