Abstract
The invention is directed to a recessible guide rail for guiding a wheel-supported vehicle along a roadway structure. The vehicle is equipped with flangeless wheels or the like for coacting with a side wall of the rail to laterally guide the vehicle along the roadway structure. It is necessary to remove the guide rail from time to time in order to realize the advantages of such a vehicle on its special rail-like roadway structure and on conventional roads. With the guide rail removed, it is possible to remove the laterally guided vehicle from its roadway structure. Also, it is possible to permit other vehicles to cross the special roadway structure of the guided vehicle. With the invention, supporting devices having lateral holding pockets which can be moved in elevation are installed where the guide rail is to be removable. Straight or curved guide rail segments which can be made of steel reinforced concrete are inserted into the pockets. The supporting devices raise the guide rail segments above the roadway surface to the elevation necessary for guiding the vehicle or lower the same in an elongated recess so that the upper edges of the rail segments are flush with the roadway surface of the roadway structure.
