Road traffic motor vehicle flow detection and accident alarm device

Abstract

The invention discloses a road traffic motor vehicle flow detection and accident alarm device. The device comprises a magnetic induction coil unit array, a traffic flow signal processor, an accident alarm device, a traffic flow management platform and a traffic signal lamp. According to distribution of the magnetic induction coil unit array, magnetic induction coil units are distributed in an array way from a stop line at an intersection to a coming road of a previous intersection; 3 to 5 magnetic induction coil units are arranged in each row of a single direction, neighboring magnetic induction coil units are arranged at an interval of 1.2 to 1.4 meters, neighboring rows are arranged at an interval of 8 to 12 meters, and the magnetic induction coil units are laid 20 to 50 centimeters below a pavement. The device can be used for detecting, pre-estimating, regulating and guiding traffic flows at any position of a road; the device can adapt to complex traffic conditions, the traffic flows can be well regulated, and safe and smooth traffic can be ensured to a maximum degree.

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
