A public passenger local traffic system with vehicles capable of driving either on streets or guided mechanically transversely in drive channels with at least approximately vertically extending switch guide surfaces being provided within an area of drive channel bifurcations or mergers, which are arranged substantially parallel to the respective outer continuous channel side and point away from the drive channel. The switch guide surfaces serve to guide the vehicles on both sides by means of switch guide rollers which are mounted laterally at the vehicle and having a substantially vertical axis. The switch guide rollers each have an at least approximately vertical roll-off surface in the operating position which cooperates with the switch guide surfaces. The switch guide rollers are supported on switch guide levers whose pivot axes are arranged at least approximately at the same height as the center of the switch guide surface. The roll-off surface of the switch guide-roller, as viewed in vertical cross section, and the switch guide surface, as viewed in cross section, are so profiled relative to one another that the switch guide roller is stabilized during the rolling on the switch guide surface in a center roll height position as a result of the profiling.
