Abstract
A traffic measuring device includes: an irradiation part to irradiate laser light at an irradiation angle of predetermined interval to form a scan layer inclined upward or downward in a gravity direction; a light receiving part to receive the laser light irradiated from the irradiation part and reflected by a vehicle; and a distance acquisition part that detects a distance to the vehicle as a detection distance for each irradiation angle using the laser light received by the light receiving part. The distance acquisition part acquires a group of the detection distance relative to a whole of the scan layer. The traffic measuring device further includes a width calculation part that computes a width of the vehicle using a shortest distance, a shortest time irradiation angle, a longest distance, and a longest time irradiation angle.
