Description

Traffic information collection system and method using wireless communication network

The present invention relates to a traffic information collection system and a method using a wireless communication network.

In general, the Global Positioning System (GPS) has been used only as a synchronization device for synchronizing user's position information (coordinates), time information, or clock synchronization. In other words, the user has obtained information such as location, time, synchronization, etc. using the location information receiver.

In addition, wireless communication networks such as cellular networks, personal mobile communication networks, and wireless data communication networks have been used for transmitting and receiving voice and various data.

Meanwhile, the communication speed information of each section of the road is very useful for the driver traveling on the road.

However, in order to measure the traffic speed of the vehicle, it is necessary to install a roof sensor on the road surface or install an ultrasonic sensor on the road surface to detect the speed of the passing vehicle.

Therefore, the development of a method that can collect traffic information, such as traffic conditions of the road using low cost and conventional equipment already installed.

Therefore, in order to solve the above problems, the present invention extracts the speed of a mobile vehicle by using the position and time information output from the location information receiving apparatus attached to each mobile vehicle, and wirelessly extracts the extracted information. The purpose of the present invention is to provide a traffic information collection system and a method for transmitting the information to a traffic information center through a communication network.
