Abstract

A transportation system with a non-rail-bound, electrically or diesel-electrically driven vehicle, has a two-pole overhead conductor system with contact wires forming supply and return conductors. The vehicle has a current collector for the supply of electrical energy through sliding contact with the contact wires. A video detector on the vehicle determines a position of the contact wires relative to the vehicle. Marking elements mark the position of the contact wires. The video detector is oriented for taking video images of the marking elements, and an evaluation unit recognizes from a recorded video image whether contact wires are present above the vehicle and, when they are present, determines their position relative to the vehicle. Through the improved recognition of the position of the vehicle relative to the overhead conductor the operational safety of the transportation system is improved.
