Road traffic control system
First Claim
1. A road traffic control system comprising:
- a traffic light positioned above one lane at an intersection;
a speed measuring device installed on guardrails on the lane; and
a light controller electrically connected to the traffic light and the speed measuring device, wherein the light controller synchronously controls the traffic light and the speed measuring device, when the traffic light changes its color to indicate stopping, the light controller controls the speed measuring device to measure current speed of vehicle that is driving through the speed measuring device.

Abstract
A road traffic control system is applied to an intersection to control traffic and includes a light support, three traffic lights, a speed measuring device, a light controller, and an alarm. The light support is installed at one lane at the intersection; the three traffic lights are installed on the light support to control traffic. The speed measuring device is installed on guardrails on the lane to measure current speed of vehicle. When one of the traffic lights changes its color to indicate stopping, the light controller synchronously controls the speed measuring device to detect the current speed of the vehicle that is passing through the speed measuring device, and compares the measured speed of the vehicle with a preset speed limit. The alarm outputs warning signals when the measured speed is above the preset speed limit.

11. A road traffic control system applied to an intersection to control traffic, the road traffic control system comprising:
-
a light support installed at one side of one lane at the intersection; three traffic lights installed on the light support and positioned above one lane at the intersection to control traffic; a speed measuring device installed on guardrails on the lane to measure current speed of vehicle; a light controller electrically connected to the traffic lights and the speed measuring device; and an alarm electrically connected to the light controller, wherein when the traffic lights are changed to yellow or red color, the light controller synchronously controls the speed measuring device to detect the current speed of the vehicle that is passing through the speed measuring device, and compares the measured speed of the vehicle with a preset speed limit, and the alarm outputs warning signals when the measured speed is above the speed limit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
