Bus priority road traffic cooperative induction method for automatic driving

Abstract

The invention discloses a bus priority road traffic cooperative induction method for automatic driving. The method comprises the steps of: upgrading road infrastructures and traffic sign marking linesfor automatic driving; optimizing a bus priority road traffic cooperative induction strategy for automatic driving; determining a bus priority road intersection signal cooperative timing scheme for automatic driving; calculating bus stop service time of bus priority guidance; determining a bus priority intersection signal cooperative induction method for automatic driving; and designing a publictransport vehicle priority passage induction plan under the disturbance of the emergency traffic incident. According to the invention, based on a traffic flow traffic operation process in an automaticdriving environment, accurate control and real-time adjustment and optimization of road speed can be realized; accurate and real-time two-way communication can be carried out between the bus and thesignal control machine, an intersection signal timing scheme can be adjusted in real time to enable the bus to pass within bus priority guarantee time, and the passing efficiency of the bus is greatlyimproved.

Description

technical field [0001] The invention relates to a bus priority road guidance method, in particular to an automatic driving-oriented bus priority road traffic cooperative guidance method, which belongs to the technical field of public traffic signal control. Background technique [0002] In recent years, under the background of the rapid development of vehicle-road coordination and Internet of Vehicles technology, the research focus at home and abroad has shifted to the emerging bus priority strategy. [0003] However, due to the different goals of traditional arterial signal coordination and bus priority methods, the bus signal priority strategy may disturb the traffic flow in the main direction of the arterial line, so that the priority benefits obtained by buses at upstream intersections may be offset at downstream intersections, thus cause priority failure. [0004] Therefore, it is necessary to further study the signal coordination of bus priority road intersections for...
