Driving speed control method for inhibiting city bus bunching

Abstract

The invention discloses a driving speed control method for inhibiting city bus bunching. According to the method, speed and position information of buses in road space are acquired in real time, a real-time dynamic driving speed adjustment method is provided for each bus on one same line to avoid a bus bunching phenomenon, and standard operation of bus teams is realized. The bus speed and the position information can reflect the road traffic operation situation. The driving speed scheme can be adjusted in real time according to actual road traffic change, and more accurate and visual indication is provided for drivers. The method can be applied to GPS / AVL vehicle equipment commonly equipped in buses at present, and the method further has advantages of strong transplantability and high reliability.

Description

Technical field [0001] The invention relates to a traffic dispatching equipment and a method, and in particular to a driving speed control method for restraining city bus chaining, so as to effectively restrain the phenomenon of bus chaining. Background technique [0002] Bus chaining, that is, the situation in which buses of the same route and different shifts arrive and stop almost at the same time, is a common traffic phenomenon in conventional bus operations. There are three hazards of bus chaining: reducing bus punctuality, reducing operating income, and increasing driving safety risks. First of all, suppose that the two shifts of bus vehicles cross, then the headway of the crossover bus is almost 0, and the headway of the bus that is located in the previous shift is at least doubled, so the bus crossover is The extreme situation of inaccurate bus stops is most criticized by the majority of passengers. Secondly, the stringing will increase the waiting time of passengers, w...

AI Technical Summary

Problems solved by technology

Secondly, the cross train will increase the waiting time of passengers, which may force some passengers to choose other modes of transportation, thus reducing the operating income of public transport, and also increasing the empty load rate of the cross train, which will increase the operating cost

Excessive bus traffic for a long time will seriously reduce the operating income of bus companies and make it difficult to ensure the sustainable development of public transport

Thirdly, the driving distance of the bus vehicles that collide with each other is less than the safe distance between vehicles, which increases traffic safety hazards, especially in weather conditions such as fog, rain, snow, dust, and hail, which can easily lead to traffic accidents

These measures are passively relieved after the occurrence of cross-traffic traffic. The improvement space is limited and often fails. It is a late-morning move in terms of the timing of improvement.
