Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for predicting a state of a road surface based on a traveling vehicle,

The present invention relates to a road surface condition prediction system, and more particularly, to a road surface condition prediction system for detecting a road surface temperature of a road using an outside temperature sensor module mounted on a traveling vehicle, The present invention relates to a weather condition-based road surface state predicting system and a forecasting method using a traveling vehicle for preventing an accident on the road by predicting freezing, snowfall and the like of a road surface by generating road surface state prediction information.

Road freezing is a common cause of traffic accidents in the winter season. In this way, if the road is frozen, not only the loss of people due to traffic accidents, but also the transportation loss, congestion and traffic control cause time and ultimately economic loss.

Therefore, it is necessary to provide a road surface condition information system that predicts whether roads are freezing in advance and provides information to drivers and road managers to prevent traffic accidents caused by road icing in advance and to take prompt action when accidents occur. to be.

1 is a schematic view for explaining a road surface condition monitoring procedure using a road weather information system (RWIS) according to a conventional technique.

As shown in FIG. 1, a Road Weather Information System (RWIS) currently installed and operated in Korea is provided with Road Side Equipment (RSE) such as a humidity sensor on the road side, The sensor is embedded in the road surface. These sensors collect weather information of the road and transmit it to the base station, and the base station transmits the information to the traffic control center through the wired or wireless communication network.

In this case, since the temperature sensor is buried in the road surface, the accurate road surface temperature can be measured in the road temperature sensor installation area, and the road surface state can be predicted relatively accurately using the measured temperature and the weather information. However, road surface condition monitoring without road surface temperature sensor and road surface temperature of vulnerable area can be estimated based on road surface temperature measured by road surface temperature sensor, but since accuracy is significantly lowered, road surface temperature and road surface condition prediction Is vulnerable.

Therefore, a method is needed to accurately measure the road surface temperature even in areas where no road temperature sensor is installed in order to convey accurate road surface information to the driver and the road manager.

On the other hand, there is an advantage that the state of the frozen road can be predicted relatively accurately through the information collected by the road surface sensor and the road surface state information. However, there is a problem that accurate road surface temperature can not be measured on the road without the road surface temperature sensor.

Actually, it is difficult to install the roadside observation equipment or the temperature sensor in all the sections in terms of budget convenience. Therefore, there is a limit to the above-mentioned disadvantages. There is a problem that a judgment error occurs.

As a prior art for solving the above-mentioned problems, Korean Patent No. 10-1409222 discloses a system called " road surface state information providing system ", which will be described with reference to FIG. 2 and FIG.

FIG. 2 is a view for schematically explaining a road surface state information providing system using vehicle information according to the related art, and FIG. 3 is a block diagram of a road surface state information providing system using vehicle information according to the related art.

2 and 3, a road surface state information providing system using vehicle information according to the related art includes an information receiving unit 10, a road surface state predicting unit 20, a road surface state information providing unit 30, (40).

The information receiving unit 10 receives the outside temperature of the vehicle passing through the area where the road surface temperature sensor is not installed, the weather information of the area, and the road surface temperature sensor temperature, and transmits the received information to the road surface state predicting unit 20.

The road surface state predicting unit 20 receives the information received by the information receiving unit 10, calculates a road surface temperature of a region where the road surface temperature sensor is not installed, and predicts the current or future road surface state.

The road surface state information providing unit 30 receives road surface state information predicted by the road surface state predicting unit 20 and transmits the predicted road surface state information to the user. The user who receives the road surface state information receives an OBE (On) Board equipment) or a smart phone, or can be confirmed through a video message system (VMS) installed on the road.

The information storage unit 40 receives and stores the road surface state predicted by the road surface state predicting unit 20 so that the road surface state predicting unit 20 predicts the latest road surface state stored in the information storage unit 40 And uses it when predicting the road surface condition. Specifically, the road surface state of the road is not determined solely by the current environment, but continuously changes from the past road surface state, so that the actual road surface state can not be predicted properly if only the current weather information and the road surface temperature are used . Here, the past road surface state stored in the information storage unit 40 may be one of dry, wet, and freezing so that the road surface state can be predicted by reflecting the past road surface state. The information storage unit 40 stores recent road surface state information so as to predict the current or future road surface state in consideration of the latest road surface state information, And freezing and freezing sections.

According to the road surface state information providing system using the vehicle information according to the related art, the road surface state can be predicted by calculating the road surface temperature of an area where the road surface temperature sensor for measuring the road surface temperature is not installed, The accurate road surface temperature can be calculated by considering both the temperature measured by the road surface temperature sensor and the outside temperature of the vehicle. Further, by using the latest road surface state information, more reliable road surface state can be predicted, the road surface state can be predicted considering the characteristics of the area, and the road surface state reflecting the real time situation of the road can be predicted in addition to the natural factor .

However, in the case of the road surface state information providing system using vehicle information according to the related art, the road surface state is predicted by using special equipment and facilities (for example, Thermal Mapping System or Road Weather Information System). In addition, although a large amount of road surface temperature is collected by using special equipment such as a thermal mapping system, depending on the topographic characteristics of the road or the road type characteristics, for example, It is difficult to scientifically identify what is. In addition, the vulnerable sections that are essential for road management are now being used in an arbitrary manner depending on the topographic characteristics of the road sections and the road type characteristics.

In addition, considering the extension of domestic roads, there is a limitation in monitoring the road surface condition by weather condition which has a great influence on the safety of road traffic only by vehicles and facilities equipped with such special equipment.
