<p>The present invention relates to a system for providing road information by using navigation, wherein road information sensed by a road information providing device which is installed on the road is transmitted to the navigation part, so that the road information may be provided to the driver. According to the present invention, the driver is able to more quickly and exactly recognize the road information that is wirelessly transmitted to the navigation side by being sensed from the road information providing device installed on the road, whereby the driver can drive safely. Further, since the driver is directly provided with the road information from the road information providing device installed on the road, the driver does not have to use a special service registration procedure or pass through a special institution which provides the road information by collecting and analyzing the road information.</p> |
