Design method of indented bus priority approach

In order to reduce the delay of buses, the indented bus priority approach was designed, its work process, platoon arrival flow, passing capacity and the used condition of advanced bus's parking area were studied.An optimized model that adapted to the needs of its platoon arrival flow and passing capacity was put forward, the fitting condition for building the indented approach was determined, its main signal and advanced signal were calculated, the suitable length of its waitting area was computed.Through an example, the delays of buses and other vehicles in the conditions of having indented approach and no-having indented approach were calculated.The results show that the average delay of buses is reduced by 3.7 s, the average delay of other vehicles is increased by 1.4 s, the delay of all passengers is reduced by 2.4 s, in the condition of having indented approach.
