Abstract
The invention discloses a method for arranging steering buses in sequence in a bus stop at the inner side of a road. The method comprises the steps that according to collected bus real-time information, time when one bus reaches a downstream intersection is predicted, passenger delay caused by steering and a signal phase sequence of the bus is analyzed, so that an optimal scheme of the bus sequence is generated, a driving waiting zone and a signal control light are arranged at the bus stop at the inner side of the road, and therefore the bus operation sequence is effectively adjusted. According to the method for arranging the steering buses in sequence in the bus stop at the inner side of the road, from the perspective of bus operation time and with the combination of bus operation experience data and real-time collected data, the time when one bus reaches the downstream intersection is accurately predicted, passenger delay caused by the driving sequence of the steering buses is accurately judged according to an original green light interval time table, and the reliable steering bus sequence is formed; the driving waiting zone is arranged at the bus stop, so that under the condition of linkage control of an outlet portion and the signal light of the driving waiting zone, the buses are rapidly and effectively lined, total delay of the steering buses in the intersection is reduced, prior passage of the buses at the signal intersection of the downstream is guaranteed, and the operation efficiency of the buses is effectively improved.
