A Section Speed Guiding Method for Bus Operation Control

Abstract:

By analyzing the location data of automatic vehicles, this paper revealed that bus headway deviation tends to increase with vehicles traveling further along the route and there exists a turning point where non directional amplification is transformed to directional amplification influenced by the random factors. Then, this paper proposed a section speed guiding method considering the dynamic threshold of headway deviation and established the control logic and the model for optimizing the guidance speed. The case application showed that the proposed control method can restrain the amplification trend of the headway deviation along the route, decrease the travelling time of passengers to some extent, and be conducive to maintaining the operation order and service reliability of the fleet.
