Abstract

The present disclosure discloses a road construction detection method and apparatus. According to one aspect of the present disclosure, a computer-implemented method for detecting road construction or obstacles on a road comprises: receiving and storing a sensor value measured from a sensor installed on the road; monitoring a change in the sensor value measured from the sensor installed on the road; determining, based on the change in the sensor value, whether there is construction on the road or not an obstacle has occurred; defining a sensor section where a change in the sensor value has been detected for a long period of time as a road construction section or an obstacle section to generate section information; and transmitting the generated section information to a base station on the road.

Description

Method and Apparatus for Detecting Road Construction The present disclosure relates to a method and apparatus for detecting road construction. More specifically, the present disclosure relates to a method and apparatus for detecting whether an obstacle has appeared on the road or whether construction is taking place, etc., using a sensor installed on the road. The following description merely provides background information related to the present embodiment and does not constitute prior art. Autonomous vehicles utilize sensors embedded in the vehicle to detect the environment around the road. Using these sensors, autonomous vehicles can detect lanes, other vehicles, and obstacles. Autonomous vehicles can use the detected information to warn the driver or control the vehicle. Accurately acquiring information about the surrounding environment is crucial for the efficient operation of autonomous vehicles. Road construction information can be obtained from information reported by the construction contractor. Road construction information may include the location, scope, and duration of the construction. Autonomous vehicles can use road construction information to drive while avoiding road construction areas. Accurate identification of road construction locations directly impacts the safe operation of autonomous vehicles. However, discrepancies may occur between reported construction locations and actual construction locations. For example, differences ranging from several meters to several kilometers may occur between reported and actual construction locations. Furthermore, it is difficult to use road construction information for autonomous driving because the start and end times of construction are inaccurate, as are the times for preparing for the actual construction and dismantling equipment.
