The present invention relates to a traffic information collection system using a mobile communication terminal, and more particularly, to a traffic information collection system using a mobile communication terminal for collecting traffic information by processing connection request data transmitted from a mobile communication terminal of a driver, ≪ / RTI >
As the economy has expanded and advanced, the number of roads and vehicles has increased. As the number of roads and vehicles increases, vehicle information, which is information on vehicles driving on the road, is collected using vehicle detection means, Intelligent Transportation System (ITS), which generates and manages traffic information including vehicle density, congestion rate, vehicle speed, and offending vehicles, is widely used.
The traffic information collecting system typically includes a vehicle sensing unit that senses a vehicle traveling on a predetermined sensing section, a controller that generates vehicle information by analyzing a sensing signal transmitted from the vehicle sensing unit, And a traffic management center server for analyzing and generating real-time traffic information.
Since the conventional traffic information collection system configured as described above is configured to generate traffic information based on the sensing signals sensed by the vehicle sensing means, reliability and accuracy of the traffic information are ensured depending on how the vehicle sensing means is configured.
Conventionally, a loop coil system, a laser system, and a radar system have been widely used as vehicle detection means. However, since the loop coil system must be buried in the road surface, installation and inspection are complicated and costly. The detection range is limited and the number of vehicles to be sensed is smaller than that of the entire traveling vehicle. Therefore, the accuracy and reliability of the detection are lowered. In the case of using the radar, the detection is not performed or the error rate is high.
UTIS (Urban Traffic Information System) has been studied variously as the communication infrastructure has been expanded and the technology of digital devices has rapidly developed. Is configured to transmit driving information accumulated in a base station (RSE) connected when a road-side equipment (RSE) is connected. However, in order to drive the UTIS, an OBE and a dedicated program are separately purchased and installed The manufacturing cost is high and there is no profit for the driver. Therefore, there is a problem that the efficiency of collecting drops remarkably due to the lack of spontaneity.
