The innovation involved in this impresses me, if they can pull this off. That's what testing is for...and according to the video, they're going to try and test this in Beijing's Mentougou District.
Watching the video, they've thought through a lot of the main issues down to the emergency evacuation in case of a major accident. The power system is brilliant-the power track is on, and therefore moves, with the bus; no need to build power lines along the route. The routes will be laid along roads where pedestrian/bike access is restricted (fenced off).
We also have the BRT buses where I'm at and it's a tremendous waste of road space with special access lanes prohibited to all other vehicles. Most drivers adhere to the rules which means shoehorning 2,3, or 4 lanes of traffic into 1, 2 or 3 lanes while the BRT lane stays empty. The white lines restricting the BRT lane have sensors on them which trigger cameras if someone tries to use that lane, resulting in a photo fine. The other drivers know that so stay out of that lane. This thing could open up more lanes to regular traffic and, in addition, can carry up to 1200 passengers (about 12 busloads) at a time.
Yeah, it's fun to make fun of the way things are done here, but really it's good to see some folks have their innovation hats on and the capital/funding to try to pull something useful off.
Hats on to them.
