Title:
TRAFFIC SIGNAL STABLE GUIDE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/077131
Kind Code:
A1
Abstract:
An optimized control method for a guide green-wave traffic signal, relating to the field of traffic signal control. The core steps comprise: 1) selecting a guide direction and a guide path; 2) selecting a guide reference intersection phase; and 3) calculating a stable guide intersection phase difference. The advantage is that a guide green wave for which the guide green-wave intersection phase difference from which a braking time is subtracted can cause a guided vehicle to obtain a green light signal turn-on time in advance at a normal braking position before each intersection stop line along the guide green wave path to effectively avoid braking, deceleration and stop operations and running fluctuations of the guided vehicle, thus causing a vehicle to stably pass through the next intersection, reducing a vehicle passing time, and improving the traffic efficiency.
