In the RUF system the vehicles drive manually to the rail system. Normally this will only be a few miles. The driver has from the start tol his ruf where he wants to go. When the ruf get close to the rail, this information is transferred to the rail system and the system takes over control and guides the ruf to enter the rail at 20 mph.

The acces is guided by magnetic fields from wires buried under the road surface. A probe in the ruf can sense if the direction is correct and make sure that the ruf is guided safely to the rail. On its way up the access-rail, the ruf is tested to make sure that the mechanical functions are OK. If it fails it will be rejected in order not to bother others. It will still be able to drive at least 50 km on a full battery, so it can easily get to the destination (workshop) via the road network.

At the junctions, the speed is lowered to 20 mph and the rufs are guided by magnetic fields at different frequencies so that it can change rail or leave the system.
