DUAL MODE BUS WITH INTERNAL AND EXTERNAL LANE GUIDANCE (MANUAL STEERING AND AUTOMATIC STEERING)
DUAL-MODE-BUS MIT INNERER UND AEUSSERER SPURFUEHRUNG (HANDLENKUNG UND AUTOMATISCHE LENKUNG)
An automatic lane guidance system for buses can be of interest in reducing the costs of infrastructure where an automatic operation cannot be considered because of a limited size network. A bus, with equipment for external lateral guidance must in this context, be at least as good as the tried wheel-rail-systems. It should have no disadvantages on the highway in comparison with the pure bus. Following a discussion of the various types of lane guidance, a proposal is made for an enclosed track configuration. By means of the introduction of guide rollers on the wheel support structure in a relatively simple fashion an enclosed lane guidance system can be achieved, which will not affect either the car body, the suspension or the axles. In order to ensure that the rear axle adheres to the lane, it must be made capable of swivelling within a small range of angular rotation. The lateral guides of the track are so low, that the car body can clear them in curves and at changes of direction. The roadway itself has a trough 2500 mm wide and 220 mm deep, in which the lateral guide units are secured to prevent any possibility of breakaway. Regarding the accuracy requirements for the lateral guidance system from the macroscopic and microscopic viewpoint, it can be useful, to arrange the lateral guidance units as additional guiderails. Where in long tunnel stretches a supply of energy is required, under these conditions very simple methods of current supply are possible. /TRRL/
