The busway is one of my favorite urban planning concepts, one I think is perfect for growing cities - cheap and supposedly effective rapid transit, with side effects including a fast way for emergency vehicles to get around town, buses able to leave the right of way and drive around problems on the 'track', and right of ways that can later be turned into heavy rail if needed. I'm looking to shatter my obsession. What are the downsides of BRT transit?
Let's say for shits and giggles that the buses have complete right of way and are basically like rail with bus stops and roads instead of track. Everyone's heard of the Curitiba BRT, and I read its efficiency was comparable to the NYC metro at one point. Are there other systems like this that work as well, or are there similar systems with issues? I'd like to hear the opinion of Cyburbians. Thanks.
