Bus priority signal control system and method based on reversible lanes at intersection

Abstract

The invention discloses a bus priority signal control system and a bus priority signal control method based on reversible lanes at an intersection, and the bus priority signal control system and the bus priority signal control method relate to the field of urban road traffic control. The bus priority signal control system is characterized in that: a reversible lane road indication board is arranged above a stop line at the front end of each reversible lane, an induction coil is arranged at the stop line at the front end of each reversible lane, a bus enter indication board and a vehicle counter are arranged at the tail end of each reversible lane, and each of four intersection signal controllers exchanges information with the reversible lane road indication board, the bus enter indication board, the vehicle counter and the induction coil on a corresponding crossing in a wireless manner; and a corresponding left-turning or straight-going bus enters a reversible lane through real-time signal control, a priority phase required by the bus is inserted timely by means of a main controller, so that the bus passes through the intersection preferentially, the phase duration is set reasonably and preferentially by combining with the counter according to the number of buses actually entering the reversible lane, an idle reverse lane is effectively utilized, and the lane utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the field of urban road traffic control, and relates to a signal control technology for buses using reverse lanes to pass in real time with priority at level intersections. Background technique [0002] At present, ordinary bus-only lanes solve the problem of bus congestion and queuing at non-intersections, so that the bus can avoid the interference of social vehicles under certain circumstances, and improve the driving efficiency of the bus. But at the intersection, due to the large number of social vehicles, it is impossible to specially open bus-only lanes, and road resources are in short supply, so buses still have not fully realized bus priority. [0003] All the reversible lanes currently set up at intersections are characterized by the reverse running of the lanes. However, at highly dense intersections, the queuing of social vehicles will cause delays to buses, and the phase signal control time at intersections is unrea...
