Expressway vehicle management and guidance command system and method based on mobile communication

Abstract

The invention discloses an expressway vehicle management and guidance command system and method based on mobile communication, and mainly solves the problems that the prior art can not effectively manage the speeding and can not offer clear guidance to the vehicle driving in misty and snowy days so that the driving safety can not be guaranteed. The realization method comprises the following steps: a dispatching platform sets the speed limit value, the front-back space value and the road boundary parameter according to the weather condition; a guidance terminal modified from a general 2G / 3G mobile phone module is allocated to the vehicle at the expressway entrance; the guidance terminal uploads the position and speed information of the vehicle in real time; the dispatching platform monitors all vehicles, and automatically sends a sound prompt to the guidance terminal in any case of speeding, path deviation and excessively short front-back space; and people on the seat send an artificial voice prompt to the guidance terminal. The system and method disclosed by the invention can accurately and comprehensively grasp the traffic information in real time, and can be applied to vehicle management, guidance command, road condition information and traffic management.

Description

technical field [0001] The invention belongs to the technical field of communication and relates to the traffic management of expressways, which can be applied to speeding management, guidance and command of expressway driving in foggy and snowy weather, and can also be used in the construction of expressway driving process control and information service systems. Background technique [0002] In recent years, with the continuous development of the economy and society, expressway construction has entered a period of rapid development, the road network has continued to increase, the interoperability has been continuously enhanced, and the traffic flow has grown rapidly. However, while the expressway exerts great social and economic benefits and shortens the space-time distance between cities, traffic safety management issues have attracted widespread attention. In particular, traffic accidents caused by speeding and bad weather such as fog and snow pose a great threat to the ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: first, the driving efficiency is low, because the visible distance is limited, and the number of vehicles that can be guided each time is small; , the number of front and rear vehicles is large and closely following, and rear-end collision accidents are prone to occur

The disadvantages of this technology are: large investment, large investment in engineering construction, cable laying, equipment and materials, and large energy consumption. If solar energy is used, it will be difficult to meet the needs of solar energy when the weather is bad; manual management is difficult and the distance is long. , overhaul and maintenance are inconvenient, and the maintenance cost is high

There are three disadvantages of this method: first, the release of information must be manually operated, the information source is not real-time, inaccurate, and the content of the information is extensive and the quantity is small; The displayed content, therefore, has a limited effect on driving guidance; third, due to the high placement of the large screen, it is difficult to install, overhaul and maintain

[0009] In summary, the existing measures cannot effectively solve the problem of speeding on expressways, and cannot obtain timely information on road conditions and vehicle driving conditions in foggy and snowy days, so they cannot give clear guidance to vehicles and cannot guarantee driving safety.
