You might be interested to learn about the successful bus rapid transit system in Curitiba, Brazil: "Buses running in the dedicated lanes stop at cylindrical, clear-walled tube stations with turnstiles, steps, and wheelchair lifts. Passengers pay their fares as they enter the stations, and wait for buses on raised platforms. Instead of steps, buses have extra wide doors and ramps that extend out to the station platform when the doors open. The tube stations serve the dual purpose of providing shelter from the elements, and facilitating the simultaneous loading and unloading of passengers, including wheelchairs, efficiently. This system of same-level bus boarding, plus the pre-boarding fare payment, results in a typical dwell time of no more than 15 to 19 seconds at a stop."[1] [1] http://www.urbanhabitat.org/node/344 http://www.urbanhabitat.org/node/344
