1. An automatic traveling system for use in combination with a steerable construction vehicle comprising:
- main traveling path means including a plurality of guide lines for the vehicle and being disposed on a traveling road surface for the vehicle which surface is disposed between a raw material site and a raw material depot of a plant;
a plurality of detecting means provided on the vehicle and each being operable so as to detect said guide lines for facilitating a steering of the vehicle;
said main traveling path means being a main traveling path provided at a substantially central position between and in parallel with the raw material site and the raw material depot of the plant, and said plurality of guidelines are a plurality of laser beams respectively projected towards said main traveling path from a plurality of projectors disposed in the raw material site and the raw material depot of the plant, said guide line detecting means including an omnidirectional laser beam receiver mounted on said vehicle;
said plurality of laser beams including a main laser beam projected from a main laser beam projector onto said main traveling path, said main laser beam being divided into two auxiliary laser beams via a half mirror and a plurality of mirrors, one of said two auxiliary laser beams is parallel with said main laser beam and passes in the vicinity of the raw material site, and the other auxiliary laser beam passes the vicinity of the raw material depot of the plant.
