In this historical moment, technology can guarantee transport systems some good solutions which seems to be quite in line with actual needs, by improving efficiency of engines (ICEs) or of travels or even rationalizing the consumption of related activities by using ITS (Intelligent Transport Systems) and by developing systems which can be sustainable through their whole life-cycle (LCC). Main results of the paper can be synthesised in pursuing the independence from the main source transport systems are based on, which is a nearly-monopoly, and use of lower unitary energy in motorised mobility in order to reduce the fuel consumption per person or per ton and - consequently - the emissions. This aim can be pursued either through higher capacity transport modes (e.g. trains, metros and automated people movers), yet guaranteeing as far as possible vehicles loaded more than their break-even in energy, or with a low level of black-oil energy used for vehicles: e.g., FEV, PHEV, natural gas for heavy-duty vehicles. The WTW analysis synthesises most of this idea.
