The project partnership is convinced that electricity-based mobility is the cleanest and most efficient mobility solution today and considers (electric) trolleybuses as the best and ready-to-use response to the urban mobility challenges in Central Europe (CE).

Project partners consider trolleybus systems as a ready-to-use transport technology for the future; for both medium-sized and large urban areas. Locally, trolleybuses are zero-emission vehicles, highly energy-efficient, able to re-use braking energy, and not losing energy while idling at bus stops. They have the lowest possible consumption of non-renewable resources (50% less compared to diesel buses) and are 100% environmentally friendly when using energy from renewable sources. Electricity to power trolleybuses can be generated basically by any available source: this constitutes public transport of the future.

In operation, trolleybuses have the lowest possible noise and vibration level in public transport, and thus offer more comfort to passengers. Their overhead wires mean visibility, which means certainty, safety and reliability to passengers; trolleybuses are less involved in road accidents. In comparison with trams, trolleybuses can reach similar passenger capacity at much lower construction cost (up to 80% lower).

Realisation requires less time, is safer and produces fewer nuisances during construction. Trolleybus systems have much shorter and less complex planning, decision periods and processes than tram networks (up to ten times shorter for realisation and construction).

In summary, trolleybuses offer a huge, but not fully used potential for making transport in CE cities safe, attractive and sustainable. TROLLEY aims at unlocking this potential and promoting also Central European cities as forerunners in the field of electric mobility.
