Traffic system with automatically transversely controllable vehicles, especially for the local public passenger traffic

A traffic system, which comprises automatically, transversely controllable vehicles, track-determining guide means extending along a desired track on the road, and cross-positional control means on the vehicle which detect the course of the guide means and act on steerable wheels of the vehicle, characterized in that for purposes of catching a track-deviating vehicle, an emergency safety channel means delimited by substantially vertical lateral web means is arranged along the road between supporting wheels of the vehicle at least within the area of such road sections as are delimited at least on one side thereof by lateral boundary means, the width of said emergency safety channel means corresponding to the maximum permissive cross-positional tolerance of the vehicle on the road under avoidance of lateral collisions, in that at least one emergency safety bolt means normally taken along in the raised position and operable to be rapidly lowered under the effect of a storage means is arranged approximately centrally in the vehicle at the bottom side thereof, which is operable to support itself at the lateral web means, and in that feeler means are provided on the vehicle which extend on both sides beyond the driving profile of the vehicle and which are operatively connected with a triggering means for the storage means, said triggering means responding during an external collision of a feeler means and being operable to fire the bolt means into the emergency safety channel means by means of the storage means.
