The external costs of transport in Italy: A quantitative approach

This paper presents the methodological approach and the results of a modelling application in the field of estimated external and social costs of transport in Italy. A simplified model has been developed to support general evaluations of the traffic management policies impact in urban and non urban areas. The model simulates the impacts on environment (changes in emissions and energy consumption) and mobility (changes in costs and journey times) caused by the policies implemented and compares the values of environmental and transport parameters given in the base scenario (ante policy) to the ones in the post policy scenario.
