Does "BRT double lane" refer to one 3.5m lane out of two, both together transporting 86k/hour due to leapfrogging efficiencies, or to both lanes together at 7m total? I think it's important to maintain consistency with the 3.5m theme!

[–] [email protected] 2 points 1 year ago (1 children)

I would guess the former, as a single bus line usually doesn't run a constant stream of buses nor express routes, but leapfrogging could allow you to run multiple bus lines along the same corridor, allowing for kinda ludicrous capacities.

BRT Performance:

Based on this data, the minimum headway and maximum current vehicle capacities, the theoretical maximum throughput measured in passengers per hour per direction (PPHPD) for a single traffic lane is some 150,000 passengers per hour (250 passengers per vehicle, one vehicle every 6 seconds). In real world conditions BRT Rio (de Janeiro, BRS Presidente Vargas) with 65.000 PPHPD holds the record, TransMilenio Bogotá and Metrobus Istanbul perform 49,000 – 45,000 PPHPD, most other busy systems operating in the 15,000 to 25,000 range.

Oh wow, I could believe that now! Tried looking up pics of Rio and Bogotá BRT to see if they are two-lane or one-lane. Some pics look as if it's 2-lane:

But it seems that's only around stations, the lanes merge into 1 later:

Wow, thanks for digging up some numbers on it. Those systems sure can move a lot of people. I certainly wouldn't mind having buses show up every 6 seconds.
