**5. Conclusion and future works**

The ComplexTrans system, full combination of rail and road, is able to take over the vast majority of overland transport of people and goods between and also within cities, and a large part of continental air transport, using only electricity supplied to the vehicles via catenary, traction battery or in the form of hydrogen converted into electricity in the fuel cell.

In doing so, the ComplexTrans system retains all the advantages of individual mobility and also mass transit takes on the character of individual transport, making it more attractive.

With the same mobility, the traffic load on cities is reduced (up to 3–10 times), parking requirements are reduced (up to 2 times) and the supply of parking is increased without taking up new space (at least 2 times).

The electromobility of the ComplexTrans system becomes attractive, and in cooperation with renewable sources of electricity, land transport becomes independent of fossil fuels and climate neutral.

The speed and safety of land transport will be increased by transferring a significant part of the transport capacity from the road to day and night fast trains, crossing Europe at speed of over 200 km/h and effectively replacing continental air transport up to a distance of about 3000 km.

The efficient combination of passenger and freight transport makes the ComplexTrans railway self-financing, and through efficient cooperation with road the rail is able to provide door-door transport for people and freight.

The implementation of the system can be phased over decades, but it is advisable to start as soon as possible because climate change will not wait, fossil fuel shortages loom and current European transport is not optimal. However, several steps need to be taken before implementation can begin.

First of all, there needs to be a broad European consensus on the implementation of ComplexTrans, because the ComplexTrans project will not happen without broad European support.

Next, the joint development of all major components needs to be done and a standard has to be developed to ensure the compatibility of all system components. All components will need to be manufactured and tested.

Furthermore, a pilot project will need to be put into operation and the ComplexTrans standard will need to be refined on this basis. It can be estimated that the pilot project can be put into operation within 10 years from the start of the project (kick-off).

As soon as the pilot project starts to show positive results, it will be possible to start the implementation of ComplexTrans on a wide scale.

It would be highly advisable for the development and provision of the basis for the production of ComplexTrans components to be carried out under the auspices of the EU, as the project is too large for the business community and, moreover, its development could be hampered by an overly competitive environment.
