Title:
ULTRA-WIDEBAND WIRELESS POSITIONING TECHNOLOGY-BASED TRAFFIC LIGHT OPTIMIZATION SYSTEM AND OPTIMIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/165154
Kind Code:
A1
Abstract:
An ultra-wideband wireless positioning technology-based traffic light optimization system and optimization method. The traffic light optimization system comprises an electronic license plate (1) affixed onto a vehicle and transmitting an ultra-wideband pulse signal; at least three interconnected and synchronized base stations (2) located beside a road and used for receiving the ultra-wideband pulse signal and uploading the moments at which the ultra-wideband pulse signal is received; and a traffic light optimization server (3) for generating real-time coordinates of the electronic license plate (1) on the basis of a positioning algorithm and the moments uploaded by each base station (2) at which the ultra-wideband pulse signal is received, positioning, on the basis of the real-time coordinates of the electronic license plate (1) and a prestored range of traffic intersection coordinates, the traffic intersection at where the vehicle is located, measuring the number of vehicles passing through the traffic intersection per second, acquiring in real-time the number of vehicles entering a waiting area in the traffic intersection per second, and optimizing the durations of red and green lights of the traffic lights at the traffic intersection on the basis of the number of vehicles passing and the number of vehicles in the waiting area per second.
