VEHICLE PARAMETER MEASUREMENT DEVICE, VEHICLE TYPE DETERMINATION DEVICE, VEHICLE PARAMETER MEASUREMENT METHOD, AND PROGRAM

A vehicle parameter measurement device (I OE) equipped with: a vehicle detector ( I 0A) for detecting the passage of a vehicle (A) traveling on a road surface at a predetermined vehicle detection position specified in a lane direction; and a laser scanning sensor (20A) for emitting laser beams toward the road surface from a position higher than the vehicle height of the vehicle (A) and scanning the laser beams along a scanning line (S) specified on the road surface, thereby obtaining scanning information representing measurement positions of the laser beams within a scanning plane (P ).
