Abstract
The pollution due to motorized urban mobility has reached worrying levels; decision-makers try to promote strategies to limit the negative impacts on the citizens’ life quality. The paper addresses the problems linked to air, noise pollution and energy consumption caused by vehicles in urban areas. The impact models used can be useful tools for traffic studies and scenario simulations; they allow a better assessment for planners and decision-makers of alternative scenarios for the asset of the transport system. The proposed models are derived from a large set found in the specialized literature. They are the result of a methodological approach consisting of a state of the art, a selection and classification of the models most significant and the elaboration of original models. A case study is proposed. The models are important tools to estimate the externalities produced by traffic on an urban road network, in particular, air and noise pollution and energy consumption. An agile calculation procedure of scenario indicators has been carried out, starting from the outputs of traffic simulations. The models and the computational method have been applied to a test network. The used models evaluate the external impacts by vehicular traffic in an urban context. The impacts are expressed through clear and easily derivable quantitative measures in relation to the flows on the links and their geometric and functional characteristics, using a common electronic spreadsheet. Therefore, the approach can be adopted by traffic planners, even as an alternative to the results produced by commercial software. The levels of pollution in many cities push public authorities to more sustainable solutions. Today, the alternative solutions can be very numerous and it is not easy to make a choice. Models of impact and performance estimation useful for comparative evaluations of alternative urban transport networks are presented to support the decision-makers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
