Description

Road Surveillance and Hazard Warning System The present invention relates to a road monitoring and danger warning system, and more specifically, to a road monitoring and danger warning system capable of reducing the occurrence of traffic accidents by detecting objects that illegally cross the road or drive against the flow of traffic at night and outputting a danger warning. Generally, roads installed in urban areas are equipped with streetlights, crosswalks, and voice warning devices to alert pedestrians or drivers of danger, thereby preventing traffic accidents. However, roads in rural or fishing villages outside the city center are mostly unequipped with streetlights, crosswalks, and voice warning systems to alert of danger; in particular, it is even more difficult for drivers to spot objects ahead on roads in rural villages that lack streetlights. In addition, most rural village roads consist of two lanes in each direction and often lack pedestrian walkways on both sides of the road. At night, jaywalking and driving against the flow of traffic frequently occur, leading to a problem of frequent traffic accidents involving jaywalking pedestrians, agricultural machinery, or agricultural machinery driving against the flow of traffic.
