[Traffic patterns regulations to reduce air pollution in the Italian cities participating in the EpiAir Project].
OBJECTIVE
to provide an overview of the mobility policies implemented by local administrations participating in the EpiAir Project in recent years (2001-2007).


METHODS
data on the resident population, housing density, and composition and evolution of vehicular fleet were collected from Istat and ACI databases. A questionnaire on the general urban circumstances and on mobility policies that have direct and indirect effects on air quality was submitted to local administrations.


RESULTS
analyses on the ACI data show that, even if there is an environmental improvement in the emissions standards of vehicular fleet, number of cars per inhabitants is higher than the European mean and a general increase in the number of vehicles has been observed, mainly of diesel-fueled vehicles. All cities, with the exception of Cagliari and Milan, completed the questionnaire. Data varied greatly in quality and quantity due to collaboration differences of the various municipalities. For each of the policy categories, many "good practices" are reported: from vehicular transport restrictions to improvements in public transport; from the promotion of pedestrian and bicycle mobility to new forms of vehicles' use and/or ownership (car-sharing, car-pooling).


CONCLUSIONS
overall, transportation policies are not very favourable towards sustainable mobility, both due to the elevated number of vehicles per inhabitants and to different barriers encountered in policies' implementation, such as the lack of an integrated approach in addressing mobility issues, the inaccurate and confusing rules in interventions' application and primarily, the lack of efficient control measures. As a result, the beneficial effects of local transportation regulations on urban air quality may be still very limited.
