Traffic signal lamp trigger control method and device

Abstract

The invention discloses traffic signal lamp trigger control method and device, relates to the technical field of traffic signal control, and aims to solve the technical problem that an existing traffic signal control mode cannot quickly respond to specific requirements or signal control requirements of emergencies. The traffic signal lamp trigger control method includes: receiving a trigger signal, and, when the trigger signal meets a preset trigger condition, according to the preset trigger mechanism, calling a corresponding trigger phase from a trigger phase library; determining triggering phase sequence, and executing a phase sequence adjustment strategy for the current phase sequence; calculating the safety transition period, and executing the preset trigger phase according to the safety transition period and the trigger phase sequence. According to the method, long-term tedious calculation is not needed, the phase and the phase sequence can be rapidly and flexibly deployed and adjusted, specific requirements or signal control requirements of emergencies can be rapidly responded, and the phenomena of traffic queuing and congestion caused by traffic events are avoided or reduced.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a traffic signal lamp trigger control method and device. Background technique [0002] Phase and phase sequence are the main parameters in the existing traffic signal control system. Phase refers to the display state of the signal group corresponding to one or more traffic streams that simultaneously obtain the right of way. The setting of the display status of the green light on or off, the phase sequence is the sequence of the phase, which refers to the order in which the signal light color changes within a signal cycle according to the set signal phase; [0003] In the current traffic management, traffic signal control generally adopts the method of fixed phase and fixed phase sequence to control traffic signal lights, which cannot provide rapid response and decision-making ability for specific traffic events, and cannot actively respond to various complex traff...

Problems solved by technology

[0003] In the current traffic management, traffic signal control generally adopts the method of fixed phase and fixed phase sequence to control traffic signal lights, which cannot provide rapid response and decision-making ability for specific traffic events, and cannot actively respond to various complex traffic states.

Regardless of the single-point multi-period control method, the system network coordinated control method, or the self-adaptive coordinated control method, although some control methods can be set to operate different phase and phase sequence control schemes for different time periods, but in the same time period Inside, the fixed phase and phase sequence are still implemented
