Abstract: Disclosed herein is an apparatus for detecting vehicles using laser scanner sensors. The apparatus includes a vehicle location detection unit, a shadow area detection unit, an estimation unit, and a control unit. The vehicle location detection unit detects information about locations and headings of target vehicles located in a local detection area from sensors arranged on the road. The shadow area detection unit calculates shadow areas corresponding to the respective sensors based on the information about the locations of the target vehicles and information about types of the target vehicles. The estimation unit estimates the locations and shadow areas of the target vehicles which will be obtained after a predetermined time has elapsed. When a specific target vehicle tries to enter one of the estimated shadow areas, the control unit outputs a speed control command used to decrease the speed of the specific target vehicle.
