Title: Method for checking traveling locus of vehicle
Inventor: OKI SADAO
IPC: G01C21/00
Filed: 1989-03-16
Abstract: PURPOSE:To enable even a beginner to easily check the traveling loci of a vehicle equipped with a light projector in an axle part by running the vehicle on the planking formed by coating the surface with a coated film contg. a photochromic photosensitive material. CONSTITUTION:The light projector 5 is disposed to the axle part in the position on the inner side of a wheel 8 and near the wheel 8. On the other hand, plural sheets of the planking 1, each of which is so shaped as to be laid in a part of, for example, an L-shaped course or the entire part thereof, and is coated with the photochromic photosensitive coating compd., are combined as the planking. The L-shaped course is provided in a building 3 subjected to shielding of solar beams. UV rays are projected toward the planking 1 from the irradiation surface of the light projector 5 directed to the planking 1 side and the photosensitive film on the surface of the planking 1 emits light when the light projector 5 is lighted at the point of the time when the vehicles enters the building 3 for checking the traveling loci. Since this light emission state is maintained for several minutes, the checking of the traveling loci of the vehicle is possible.
