Abstract
A method and system for guiding a vehicle through a tunnel or other space. A linear beam of light is projected along a certain path through the space. As the vehicle travels into the space, the linear beam is shined upon the vehicle. Visually aligning an indicator on the vehicle with the linear beam of light indicates to the driver that the vehicle is traveling directly down the center of the path. The alignment occurs by the driver making manual adjustments of the vehicle'"'"'s direction by turning wheels of the vehicle.

14. A system for guiding a vehicle traveling through a space, comprising:
-
an indicator on the vehicle; and
at least one light source mounted to a surface above the path to project a linear beam of light downwardly along the path through the space, the beam being projected both in front of and on the vehicle;
wherein when the indicator is aligned with the beam of light, the vehicle is traveling along the path. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
