China straddling bus [ENGLISH computer voice over] the only English video

0:18At present, there are mainly 4 types of public transits in China: 0:21subway, light-rail train, BRT, and normal bus. 0:26They have advantages and disadvantages, for example, subway costs a lot and takes long time to build;0:32BRT takes up road spaces and produces noises as well as pollution to the air. How to develop environmental-friendly public transportation? Straddling bus provides a solution. Let’s watch a demonstration.0:46This is what the interior looks like: it has huge skylight that will eliminate passengers’ sense of depression when enter.0:56The straddling bus combines the advantages of BRT, it is also a substitution for BRT and subway in the future. 1:17As you all know, the majority vehicles on the road are cars, the shortest vehicles are also cars. 1:25Normally our overpass is 4.5-5.5 m high. 1:31The highlight innovation of straddling bus is that it
runs above cars and under overpass. 1:35Its biggest strength is saving road spaces, efficient and high in capacity. 1:42There are also two ways in dealing with station platform. One is to load/unload through the sides; the other is using the built-in ladder so that passengers can go up and to the overpass through the ceiling door.1:54There are two parts in building the straddling bus. 1:57One is remodeling the road, the other is building station platforms. 2:02Two ways to remodel the road: we can go with laying rails on both sides of car lane, which save 30% energy;2:10or we can paint two white lines on both sides and use auto-pilot technology in the bus, which will follow the lines and run stable.2:19Another strength of straddling bus is its short construction life cycle: only 1 year to build 40 km. Whereas building 40-km subway will take 3 years at best. 2:30Also the straddling bus will not need the large parking lot that normal buses demand. It can park at its own stop without affecting the passage of cars. 2:41Straddling bus is completely powered by municipal electricity and solar energy system. In terms of electricity, the setting is called relay direct current electrification. 2:55The bus itself is electrical conductor, two rails built on top to allow the charging post to run along with the bus, the next charging post will be on the rails3:04before the earlier one leaves, that is why we call it relay charging. 3:11The set here is super capacitor, a device that can charge, discharge and store electricity quickly.3:18The power it stores during the stop can support the bus till the next stop where another round of charging takes place, achieving zero toxic gas throughout the process.3:28Nowadays many big cities have remodeled their traffic signaling system, to prioritize public buses, that is to say when a bus reaches a crossing, 3:37red light on the other side of the fork will turn on automatically to give buses the right of way.3:43Our straddling bus can learn from this BRT method. The bus is 6 m in width and 4-4.5 m high.3:51How will people get off the bus if an accident happens to such a huge bus? Here I introduce the most advanced escaping system in the world. 4:00In the case of fire or other emergencies, the escaping door will open automatically. I believe many of you have been on a plane.4:09Planes are equipped with inflated ladder so people can slide down on it in emergency. I put the escaping concept into the straddling bus.4:19The bus can save up to 860 ton of fuel per year, reducing 2,640 ton of carbon emission.4:27Presently we have passed the first stage demonstration and will get through all of the technical invalidation by the end of August.4:34Beijing’s Mentougou District is carrying out a eco-community project, it has already planned out 186 km for our straddling bus. Construction will begin at year end.4:46Thank you.
