Current land transport is not optimal. Road transport is congested and rail transport is under-utilised and unprofitable. Land transport is based on the burning of fossil fuels and contributes to climate change. Hence the EU’s desire to push for electric propulsion on the road and to make rail the backbone of Europe’s transport system. Developments in transport are solving some problems but creating others. The ComplexTrans project addresses private and public transport of people and freight in and between cities and removes current and upcoming transport problems in a natural way (without restrictions and subsidies), based on the mutual adaptation of electric road and rail vehicles and their deep intermodal and multimodal cooperation and using fast mixed passenger/freight trains. The solution for land transport is not competition but cooperation between road and rail.
