Title:
VEHICLE/ROAD INTERACTION SIGNAL CONTROL METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/156597
Kind Code:
A3
Abstract:
A vehicle/road interaction signal control method and apparatus, comprising: expanding the range of an intersection, extending to an upstream intersection along each approaching vehicle direction, and determining signal phases according to traffic flow conditions (S101); acquiring the current speed and the current position of each moving target in each phase (S102); according to the current speed and the current position of each moving target in each phase, calculating the time for each moving target to reach the intersection (S103); according to the time for each moving target to reach the intersection, obtaining a time sequence of the moving targets in each phase for reaching the intersection; according to the time sequence of the moving targets in each phase for reaching the intersection, determining a release order and a release duration for each phase (S105); sending information to onboard terminals. The onboard terminals thus calculate guide speed intervals in real time, and vehicles adjust vehicle speeds according to road conditions in combination with the guide speed intervals (S108), so as to reach the intersection during a green light, thereby preventing delays caused by stopping at the intersection, increasing the passage efficiency of the whole intersection, and reducing energy consumption.
