As described above, in order to evaluate the performance of the image-type vehicle sensor, a mobile traffic information collection device for acquiring traffic information of a measurement interval detected by a video-type vehicle detector is used.

However, the conventional traffic information collecting device has a problem that the control device, the data collecting device, and the image storing device are separately constructed, which takes a long time to install and thus the efficiency is low.

In order to solve such a problem, a traffic information collecting device in which the control device, the collecting device and the image storing device are integrally integrated to greatly reduce the installation time of the traffic information collecting device, and a system for remotely monitoring such a traffic information collecting device I want to.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. In addition, the embodiment described below does not unduly limit the contents of the present invention described in the claims, and the entire configuration described in this embodiment is not necessarily essential as the solution means of the present invention.

However, the components shown in Fig. 1 are not essential, so that a traffic information collecting apparatus having components having fewer or fewer components may be implemented.

Hereinafter, the components will be described in order.

First, the detection unit 100 may include a laser sensor 110 and a camera 120 for detecting a vehicle running on a measurement region detected by a video-type vehicle detector using a camera.

The second laser sensor 112 senses a vehicle entering the measurement period, (Departing) from the vehicle, thereby generating second sensing data.

In the present invention, a multi-lane vehicle can be detected by using a laser sensor for measuring a distance to a vehicle sensed by a laser sensor.

Since laser sensors that can not measure the distance are installed outside the roads of multiple cars, errors occur when calculating the traffic volume and the vehicle speed by recognizing the vehicles traveling in different lanes as the same vehicle.

However, in the case of using the laser sensor for measuring the distance, it is possible to detect which vehicle the vehicle senses by using the measured distance value, so that the control device 400, which will be described later, When calculating the speed, you can calculate the traffic volume for each lane.

For example, when the vehicle A and the vehicle B travel in different lanes, the vehicle A is detected by the first laser sensor 111 using the conventional laser sensor, the vehicle B is detected, and the conventional laser sensor When the vehicle A is detected after the vehicle 2 is detected by the used second laser sensor 112, the control device 400 determines whether the vehicle A and the second laser sensor 112 sensed by the first laser sensor 111 The detected vehicle B is recognized as the same vehicle, and the traffic volume and the vehicle speed are calculated.
