Urban highway bus signal priority method

Abstract

The invention discloses an urban highway bus signal priority method. According to the method, real-time interaction between a bus and a signal control system is realized by use of an open interface at a control end of a networking signal control center; the bus arrival condition is detected in real time by virtue of an RFID (Radio Frequency Identification) detector distributed at a road junction, so that predication on waiting state of buses at the road junction and next-period bus arrival time is realized; in a current period, a phase locking / unlocking instruction is transmitted to the signal control system, so that a bus go-through green light time is dynamically prolonged; before the beginning of a next-period, whether to reserve a bus exclusive period or not is determined according to bus queuing and bus arrival condition predication. According to the method, upgrade reconstruction of a signaler at the road junction is not needed, and the implementation cost and risk is low; while real-time signal priority is supplied to buses, invalid use of the bus exclusive period is avoided under the condition that no bus arrives at the road junction, and negative influences of the bus signal priority on social vehicles are reduced.

Description

technical field [0001] The invention relates to the field of intelligent traffic signal control, in particular to a method for prioritizing public transport signals on urban roads. Background technique [0002] Bus signal priority is one of the effective ways to improve bus service level. Its principle is to provide priority signals for bus vehicles in intersection signal control, thereby reducing the travel time of bus vehicles and improving operating efficiency. However, the current research results show that in the case of mixed lanes, due to the influence of social vehicles, the operation of buses is subject to many restrictions. At the same time, because the bus starts slowly, it will also hinder the driving of social vehicles, so the priority of bus signals cannot be obtained. Ideal implementation effect. The setting of bus-only lanes can separate buses from social vehicles, effectively reduce the interaction between buses and social vehicles, and improve bus service ...
