An Intelligent Traffic Indication System Applied in Smart City

Abstract

The present invention provides an intelligent traffic indication system applied to a smart city, which comprises an infrared transmitting device, an infrared receiving device, a timing device, a first comparison device, a first trigger device, an image acquisition sensor, an image processing device, an image analysis device, A pressure test sensor, a signal processing device, a second comparison device, a second trigger device, an external trigger device, a remote transmission device, a traffic indication device, and a central control device, wherein the road vehicle congestion is determined by an infrared transmitting device and an infrared receiving device, Then, the pressure test sensor is used to monitor whether the congested road section is relieved, and the image acquisition sensor is used to obtain the type of vehicles passing through the intersection. In addition, the signal processing device is used to improve the accuracy of the pressure test, and external compensation is used to improve the clarity of the image.

Description

technical field [0001] The invention relates to the field of traffic, in particular to an intelligent traffic indication system applied to a smart city. Background technique [0002] A traffic-direction measure used to assign the right-of-way to the flow of traffic in time where traffic separation cannot be achieved at a road intersection. The function of traffic signals is to scientifically distribute the right of way for vehicles and pedestrians on the road, so that they can pass smoothly in an orderly manner. [0003] Traffic control, also known as traffic signal control, or urban traffic control, is to rely on traffic police or use traffic signal control facilities to direct the passage of vehicles and pedestrians with the changing characteristics of traffic. [0004] Traffic control uses modern communication facilities, signal devices, sensors, monitoring equipment and computers to accurately organize and regulate running vehicles so that they can run safely and smooth...

AI Technical Summary

Problems solved by technology

That is, the traffic indication system is controlled by the staff according to their own judgment, so the accuracy is low, and it requires a waste of manpower. Even if some control systems can realize automatic control, their identification accuracy is low, and they cannot effectively identify vehicle congestion and traffic jams. In the event of congestion relief, specific information on vehicles passing through the lane cannot be obtained
