The SFMTA says it’s impossible for stations on the coming Van Ness Bus Rapid Transit route to have one of the key recommended features of BRT: High platforms, at the same level as bus floors, that allow passengers to quickly step onto the bus. SFMTA planners say that complications with the design of Muni’s buses mean there’s no practical way to make high platforms work, at least without adding high costs associated with new equipment.
Platform-level boarding is on the list of “BRT Basics” included in the Institute for Transportation and Development Policy’s BRT ”Scorecard”:
Having the bus-station platform level with the bus floor is one of the most important ways of reducing boarding and alighting times per passenger. Passengers climbing even relatively minor steps can mean significant delay, particularly for the elderly, disabled, or people with suitcases or strollers. The reduction or elimination of the vehicle-to-platform gap is also key to customer safety and comfort.
But according to an SFMTA report [PDF], a 14-inch high platform, matching the height of a Muni bus floor, “increases capital and operational costs, reduces operational reliability and passenger comfort, and provides no discernable benefit.” Instead, SFMTA planners recommend 6-inch high platforms, the same as those on Market Street.
High platforms would be scratched by the “wheel lugs” that stick out from the side of bus wheel wells, the report says. The Americans with Disabilities Act apparently requires buses to stop with no more than a three-inch gap between the bus and platform. Otherwise, a “bridge plate” must be deployed from the side of the bus to the platform for wheelchair users. The wheel lugs apparently stick out five inches.
