Intelligent expressway traffic monitoring system based on GPS and GPRS

Abstract

The invention discloses an intelligent expressway traffic monitoring system based on the GPS and GPRS. The intelligent expressway traffic monitoring system is characterized by comprising a background monitoring center, intelligent traffic equipment and data processing centers arranged on an inlet and an outlet of an expressway. The intelligent traffic equipment is allocated to vehicle users when vehicles enter the expressway, recycled when the vehicles exit the expressway and used for recording driving states of the vehicles and sends recorded vehicle information to the background monitoring center in real time; the data processing centers are used for recognizing vehicles when the vehicles enter the expressway and writing the recognized vehicle information in intelligent traffic equipment to be allocated; vehicle historical driving states are read according to recycled intelligent traffic equipment when the vehicles exit the expressway, and billing is carried out according to vehicle historical driving tracks or mileages; the background monitoring center judges states of the vehicles according to the vehicle information which is obtained in real time and sends warning messages or prompts according to the states of the vehicles. The system can precisely bill, relieve traffic jam, improve traveling efficiency, and meanwhile guarantee orderliness and smoothness of the expressway.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, in particular to an intelligent monitoring system for expressway traffic based on GPS and GPRS. Background technique [0002] In recent years, the rapid development of expressways has brought great convenience to people's travel, and at the same time boosted the rapid development of regional economy. While the expressway brings benefits, it also brings a series of disadvantages and problems: (1) The difficulty of toll collection. With the continuous expansion of the road network structure, there have been multiple loops and paths between rings, and there are multiple paths between two points with the same starting and ending points, which makes the toll collection and demolition of each path and road investor into problems. At present, toll charges are mainly based on the shortest path method, that is, whether to participate in splitting is determined according to the distanc...

AI Technical Summary

Problems solved by technology

While expressways bring benefits, they also bring a series of disadvantages and problems: (1) Difficulty in charging tolls

As the road network structure becomes more and more complex, the contradictions brought about by this split method become more and more prominent

(2) Fee evasion

However, this method needs to build an electronic sign station, and the reader needs to be replaced and upgraded later, and the system construction and maintenance costs are high

[0004] Aiming at problems such as toll evasion, speeding, and illegal parking on the expressway, the main method currently adopted is to install monitors, speed measuring radars and other devices at fixed points to monitor the driving conditions of the expressway. Although this monitoring method restricts the driver to a certain extent However, it is easily affected by external factors such as weather and light intensity, and it cannot really monitor the whole process, and it cannot fundamentally solve the illegal behavior of drivers.
