Road traffic motor vehicle flow detection and accident alarm device

Abstract

The invention relates to a vehicle flow detection and accident alarm device for highway traffic. The device includes a magnetic induction coil unit array, a traffic flow signal processor, an accident alarm device, a traffic flow management platform and a traffic signal light; the distribution of the magnetic induction coil unit array is: at the intersection, from the stop line to the previous intersection Magnetic induction coil units are distributed in an array under the coming and going road, with 3 to 5 magnetic induction coil units in each row in one direction, the distance between adjacent magnetic induction coil units is 1.2 to 1.4 meters, and the distance between the front and rear rows is 8 to 12 meters; The coil unit is laid 20-50 cm below the road surface. The invention can detect, estimate, regulate and induce the traffic flow at any position on the road, can adapt to more complex traffic conditions, better complete the regulation of the traffic flow, and ensure the safe operation and smoothness of traffic to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation vehicle flow information collection, and in particular relates to a road traffic motor vehicle flow detection and accident alarm device. Background technique [0002] Transportation is the artery of urban economic development, and plays an inestimable role in the development of urban economy, the improvement of people's living standards and the overall construction of smart cities. With the acceleration of urbanization, urban problems such as traffic congestion, traffic accidents, and traffic management have become the most common and thorny problems. No matter whether it is a developed country with strong economic and technological strength or a developing country that is rapidly emerging, there is no problem. The exception is plagued by these problems. Therefore, it has become an urgent need for road traffic control to improve the utilization rate of existing roads and ensure...

AI Technical Summary

Problems solved by technology

Its shortcoming is that it can only distinguish between long vehicles and short vehicles, and when adjacent lanes pass at the same time, the number of vehicles will be missed, resulting in errors

However, the induction coil detectors currently on the market can only complete some simple detection tasks, such as the measurement of vehicle speed and road occupancy, etc. Such detectors also cannot meet the control requirements of traffic flow
