THE BUS DRIVEN ON A TRACK - DUAL MODE BUS

DER SPURGEFUEHRTE OMNIBUS - DUAL MODE BUS

The feasible technical developments in the bus as a part of the total traffic concept are discussed; the aim of these developments is automatic guidance. Two different designs of such an automatic guidance system were developed, one based on electronics, and the other on a mechanical device. With the mechanical control, guide rails are laid on the carriageway, and these have contact with special guidance rollers. These directly affect the steering of the wheels. Here the road costs are great, and the problem of switching points and crossings has to be solved as on the railways. This system is of interest where many buses travel a relatively short stretch and this stretch can be exclusively reserved for the bus. With the electronic control a simple guidance cable is placed in the bus carriageway and provided with a frequency of about 10 khz. Antennae in the vehicle pick up the electromagnetic signal for evaluation in an electronic controller which directly affects the steering of the vehicle. This system is of interest where few buses travel over a long stretch. The safety and reliability of these systems in all operating conditions is to be examined on a special experimental road, and a continuous test is to be undertaken with several vehicles. (TRRL)
