According to the scheme, the invention relates to a traffic facility which comprises a plurality of stations, a plurality of motion routes, a plurality of trolleys, a plurality of switching device, a plurality of input devices, a starting position identification unit and a control system. Under control of the control system, the trolleys can be switched between all motion routes; as for each switching position, the motion route where one trolley runs previously is called as a previous route, and the motion route where the trolley will be switched to is called as a target route; each trolley has a first state and a second state, and the trolleys in the first state and the trolleys in the second state can run on one target route jointly; the control system controls parts of trolleys on the target route to execute the sliding process, and therefore two trolleys in the joint travelling state are staggered. The traffic facility has the beneficial effects of being safe and reliable.
