[automatically translated] Air pollution is of particular concern, especially in urban areas, both for the intense production of pollutants, with frequent acute episodes and for the large number of citizens exposed to the risk of damage to health. Furthermore, in urban centers, emissions of pollutants spread by vehicle exhausts (CO, NOx, VOC, PM10, PAH, etc.) Take place in extremely unfavorable conditions for the operating states of vehicular flow, which is interrupted due of the presence of intersections (signalized and not) particularly close to each other, and the built which inhibits the rapid dispersion of the exhaust gases into the atmosphere. The predominance of the private than in the public transport, especially within the urban road network, It requires the implementation of specific strategies aimed at meeting the demand for mobility, in a logic of respect and protection of the environment and the health of citizens. As a result of the great complexity in traffic management, especially in the medium cities - large, and the need to comply with increasingly stringent regulations on environmental protection, the government frequently resort to emergency measures (traffic jams, number plate, Sundays feet, etc.) with results mostly poor, rather than planning coordinated actions, type "non-structural", to be realized in the short term. In this regard, suffice it to note that until 1998 the city will have a PUT (Urban Traffic Plan) were only 73, despite the New Highway Code (Legislative Decree no. 30 April 1992 n. 285) requires its preparation for all municipalities with a resident population of over 30,000 inhabitants and for those affected by significant problems with regard to traffic, with a resident population less than the aforementioned threshold. In light of the synthetically exposed, in the present work are resigned some specific strategies of long, medium and short term, to mitigate certain negative externalities of road transport, such as air pollution in urban areas. In particular, the short-term strategies were discussed such as: i) the establishment of the limited traffic zone (ZTL) in the historic centers of cities; ii) the increase in the number and extent of the reserved lanes; iii) the differentiation of tariffs for paid parking in areas with particularly heavy traffic; iv) the creation of "blue axes"; v) the establishment of information systems for users, even via SMS. The study also takes into account the experience gained in the city of Palermo, where the City Council has prepared, in the course of 2008, a specific anti-smog plan, in order to counteract the harmful effects of the traffic that negatively affects the quality of life and weakens the opportunities for further socio-economic development of the city itself.
