Bus priority signal control method based on multi-turn bus shared lane

Abstract

The invention discloses a method of controlling a bus priority signal based on a multi-turning bus shared lane. The method comprises the steps: a multi-turning bus shared lane is additionally arranged between a straight-going lane and a right-turning lane of each entrance lane at an intersection; bay bus stations for left-turning, straight-going and right-turning buses to stop are constructed in sequence from front to rear at the places, where certain distances are away from the stop line at the entrance of the intersection; a group of bus station signal lamps are arranged above the stop point of each bay bus station; because of a phase difference between the main signal of a main signal lamp and the bus station signal of each bus station signal lamp, the green lamp of each bus station signal lamp is turned on earlier than the green lamp of the main signal lamp; when a bus enters the intersection from the multi-turning bus shared lane and arrives at the stop line of the entrance, the main signal lamp turns green, the bus and other motor vehicles pass through the intersection together; when the normal passing of other motor vehicles are not influenced, bus priority is realized.

Description

technical field [0001] The invention belongs to the field of urban road traffic signal control, relates to signal timing at road intersections, in particular to a bus priority signal control method for a bus shared lane. Background technique [0002] In response to the rapid increase in the number of motor vehicles in cities and the increasingly serious traffic jams, bus lanes have been opened up, with the purpose of giving priority to buses. However, these bus-only lanes are only set on road sections, which can improve the traffic capacity of buses. Because no bus-only lanes are set at intersections, buses still need to wait in line at intersections, and there is no signal priority , it is difficult to realize real bus priority. Contents of the invention [0003] The purpose of the present invention is to realize the full priority of the bus under the condition that the bus does not affect the normal running of other motor vehicles at the intersection, and proposes a bus...
