Road traffic monitoring method

Abstract

The invention provides a road traffic monitoring method. The method is realized based on a proximity switch and a plurality of piezoelectric patches, the piezoelectric patches and the proximity switchare embedded in the road surface, the plurality of piezoelectric patches form a piezoelectric detection unit, and the piezoelectric detection unit spans the whole lane, and is composed of a primary-stage detection unit and a secondary detection unit, wherein the primary-stage detection unit and the secondary detection unit are perpendicular to the road direction. Data collected by the two detection units are subjected to simple logical operation, and then various types of traffic information can be obtained, and traffic monitoring and management are realized. The road information monitoring network can be encrypted, a data basis is provided for traffic big data, and the calculated flow precision is greatly improved.

Description

technical field [0001] The invention relates to a road traffic monitoring method. Background technique [0002] my country is in a period of accelerating infrastructure construction, and road transportation facilities are becoming more and more perfect. According to statistics from the Ministry of Transport, as of July 2017, the mileage of expressways in my country has exceeded 131,000 kilometers, ranking first in the world. The transportation infrastructure has greatly promoted the development of the region. However, due to factors such as drivers' driving skills and road safety factors determined by terrain factors, the road traffic safety problem is still severe: the problem of overloading and speeding remains the same, and the density of detection road sections for monitoring overloading and speeding is too low, which still belongs to "spot checks". If the wired sensors are arranged in the traditional way, due to the extremely large span of the traffic facilities, a la...

Problems solved by technology

However, due to factors such as drivers' driving skills and road safety factors determined by terrain factors, the road traffic safety problem is still severe: the problem of overloading and speeding remains the same, and the density of detection road sections for monitoring overloading and speeding is too low, which still belongs to "spot checks". If the wired sensors are arranged in the traditional way, due to the extremely large span of the traffic facilities, a large amount of materials will be consumed, such as transmission cables and various probes for measuring various parameters, as well as various energy sources, such as the energy consumed on the transmission line Electricity, etc.
