In the present report, these types hove been aggregated into the three piliors of sustainable development: social, economic ond environmental (see clso UNECE, 2012). Transport systems should be also affordable for societies, therefore, public expenditure in a sustainable form as well as alternative funding options should be also evaluated. In order to evaluate transport safety, particularly in the road sector, the current situation, trends and controlling factors (e.g. speeding and drink-driving) of traffic accidents should be assessed. Finally, transportation negatively affects the environment through the consumption of non-renewable fuels, local and GHG emissions, noise and ecosystem degradation.
