San Francisco’s Van Ness BRT

The ROI on bus lanes is remarkable:

Another benefit of the lanes is a more consistent trip time for riders. Travel-time variability decreased by up to 26% northbound and 55% southbound, according to the data. And the lanes appear to have encouraged more people to take the bus, with ridership increasing 13% in the first week the Bus Rapid Transit lanes were in service, a pattern that has remained consistent in the following weeks, Tumlin said.
