Crossing traffic flow monitoring system

Abstract

The invention discloses a crossing traffic flow monitoring system which relates to the field of traffic flow monitoring. The crossing traffic flow monitoring system comprises a pressure sensor, a monitoring device, an A / D signal converter and a microprocessor. The pressure sensor is arranged at an area below a crossing channel and is used for monitoring the number of vehicles on the road. The pressure sensor transmits one signal to a roadside monitoring device when the pressure sensor is pressed once. When the monitoring device receives two signals, the monitoring device adds one to the numberof passing vehicles and simultaneously updates the number of passing vehicles in other lanes. The monitoring device transmits all monitored data to a background server. The background server performsposition-specified and position-specified storage and analysis on data, performs road condition analysis and predication on each road segment based on existing data through a fuzzy calculating method, and transmits analysis data to a traffic center. The crossing traffic monitoring system can supply pollution-free traffic flow detection and furthermore performs fuzzy calculation processing on themeasured traffic flow, thereby preventing a traffic jam.

Description

technical field [0001] The invention relates to the field of traffic flow monitoring, in particular to a crossroad traffic flow monitoring system. Background technique [0002] With the development of human economy and society, automobiles play a pivotal role in people's lives as a means of transportation. While it brings great convenience to human beings, it also makes people face many challenges such as traffic congestion and road safety problems during driving. [0003] At present, the main way to solve these problems is to invest in road facilities, but because the cost is getting higher and higher, it is unsustainable, and the monitoring of road traffic conditions has become an important task of the traffic control department; On the one hand, the cost of road widening is high, and the cost of land in the city is very high, and the occupation of land resources is a greater cost. On the other hand, for the old city, the road cannot be reconstructed or widened; therefore,...

Problems solved by technology

[0003] At present, the main way to solve these problems is to invest in building road facilities, but because the cost is getting higher and higher, it is unsustainable, and the monitoring of road traffic conditions has become an important task of the traffic control department; On the one hand, the cost of road widening is high, and the cost of land in the city is very high, and the occupation of land resources is a greater cost. On the other hand, for the old city, the road cannot be renovated or widened; therefore, through reasonable control of traffic flow, guide the congestion area to solve the technical problem of urban congestion

[0004] The existing monitoring system needs cameras to monitor the intersections, which cannot accurately judge the traffic flow, and requires staff to monitor in real time. While the work efficiency is low, the measured data cannot be analyzed and processed; some use geomagnetism Coils, etc. use magnetic field technology to monitor traffic flow. If the magnetic field is turned on for a long time, it will generate a large amount of electromagnetic radiation to the surrounding people or the environment, endangering the safety of drivers.
