Abstract: Vehicle measuring apparatus and method are disclosed to accurately measure height and width of a vehicle moving at a high speed. The vehicle measuring apparatus includes: a plurality of laser sensors separated from the road surface with a predetermined height and installed closely to each other corresponding to width of every roadway on the road, and receiving a reflection light of a laser light emitted onto the road from the plurality of the laser sensors and outputting a vehicle measurement signal; and a processor means electrically connected to the laser sensors and calculating height and width of the vehicle on the basis of the signal to measure the vehicle and previously stored installation information of the plurality of laser sensors.

Abstract: In an apparatus and a method for measuring a queue length of vehicles, by installing a camera toward a direction same with a proceeding direction of vehicles on the road, photographing images of the road at the rear of vehicles and measuring a queue length of vehicles, it is possible to measure a queue length of vehicles accurately. The apparatus includes a camera for photographing the rear of vehicles on the road; an image converter for converting analog image signals corresponding to images photographed by the camera into digital image signals; and a control unit for extracting characteristics of vehicles from the converted digital images, calculating positions of vehicles on the road on the basis of the extracted characteristics and calculating a queue length of vehicles on the road on the basis of the calculated positions of vehicles.
