<p>The invention concerns an installation comprising a traffic lane whereof certain sections at least are provided with longitudinal reference marking (10) for the nominal trajectory and with vehicles (18) each of which bears a guide assembly through the steering axle control, with a module forming an image of the track ahead of the vehicle (18) and operating the marking image and an optical guiding module computing the direction to be imparted to the steering axle wheels to follow the nominal trajectory and a deflection servo-motor controlled by the guiding module. The track bears, at least on certain sections, lateral guides (14, 16) and the vehicles, whereof the front axle at least is a steering axle, are provided on each axle, with rollers (24) with vertical axis pressing on the guides (14, 16) in the event of excessive divergence relative to a nominal trajectory on the track.</p> |
