摘要：
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 inter
