However, in order to acquire external information such as the signal state of a traffic light even in the case of using such a driving information providing method, a driver must visually confirm a traffic light fixedly installed on the road. In the case of rain or fog, It is difficult to accurately grasp the signal state of the traffic light.

Also, when the visibility adjustment of the driver is delayed due to the backlight of the vehicle traveling in the opposite direction or the sudden change in the light intensity after passing through the tunnel section, or when the visibility can not be secured due to the frontage of a large vehicle such as a bus or a truck, The risk of accident can be exposed by not immediately confirming the signal state of the traffic light.

In order to provide a more effective and safe operation in such a signal section, a method of providing information of a traffic light is proposed. In general, however, only signal change information is provided in a fragmentary manner, There is a problem that the driver feels inconvenience of driving by controlling the vehicle itself uniformly according to the signal change information without considering the driving propensity of the driver.

In addition, TPEG (Transport Protocol Expert Group) is proposed as a measure to measure the traffic congestion. TPEG collects information by collecting traffic information on tens of thousands taxi, bus, , A technology that calculates the time spent by collected vehicles via a location transmitter or GPS installed at each intersection and determines the road condition based on the time spent.

However, in the case of measuring the traffic congestion through the TPEG, the traffic pattern in which the bus or taxi stops for riding or getting off the passenger is reflected in the traffic congestion as it is, In order to increase the profit of the area, the traffic of the actual traffic is not accurately recognized because it is reflected in the traffic congestion. There is a falling problem.
