Dual-mode vehicle
A dual-mode vehicle (DMV) is a vehicle that can operate on conventional road surfaces as well as a
Dual-mode vehicles are commonly electrically powered and run in dual-mode for power too, using batteries for short distances and low speeds, and track-fed power for longer distances and higher speeds. Dual-mode vehicles were originally studied as a way to make electric cars suitable for inter-city travel without the need for a separate engine.

Technology

Similar to model trains, the ground level power supply is transported through the metal track to the vehicle. Because of the health risks with higher voltages in real systems, the power rail is only switched on when a vehicle is covering the section, to prevent pedestrians from being injured. This system is used for trams in Bordeaux is called Alimentation par Sol.[4]
Hybrid vehicles differ from dual-mode vehicles because they may not be fed by another energy source during operation.
Dual-mode systems under development include the TriTrack, the RUF, Roam Transport's CargoRail and
Logistics
On the main urban arterial streets, a catenary system may serve both public transport and freight forwarders. This makes the operation of trolleybuses more efficient because of the additional income from freight forwarders. The operation of dual-mode trucks is not bound to the electric system. The distance from the logistics center to the inner city is driven in a conventional way. Also, there is the possibility to reach all clients aside the catenary system.
Motivation
Cities with slow air exchange (inversion) and high emission figures (
