The forecasting of the roadside pollutant levels to evaluate traffic management measures in Palermo.
2015
The road transport has become the major source of environmental degradation in urban centres. It produces negative externalities (i.e. pollution, delay, etc.) that are usually connected with the queues of traffic flows and the congestion of the road network. The quantitative estimation of roadside pollutant levels is very complex. Many variables are involved such as the type of vehicle (characterized by different antipollution devices, used fuels, engine temperatures, maintenance level of engines, etc.), the different cinematic conditions of the flows, the urban/road network structure, the weather conditions, etc. Therefore it is important to develop scientific tools able to predict roadsid…
Estimating traffic operations at multi-lane roundabouts: A case study
2014
This paper addresses traffic modeling issues at urban multi-lane roundabouts where, despite circulating vehicles have priority, negotiation of the right-of-way can occur between antagonist traffic flows, as a result of minor drivers’ failing to obey the nominal operating rule (stop or yield control). Existing models for the estimation of operational performances have the shortcoming of not representing the interdependencies between entering and circulating vehicles at multi-lane roundabouts. An analytical capacity model derived from field observations was developed for this kind of intersections in a previous study. The complexity of the model lies in the difficulty of observing the behavio…
Dealing with the right of way in advanced traffic simulation. A characterization of drivers' behaviours in a multi-agent approach
2017
International audience; With the emergence of ADAS and autonomous vehicle, the need of simulation software to test advanced systems and models is unavoidable. The objective of this work is to characterize, in a multi-agent approach, the traffic vehicles behaviours, and to model them in a versatile traffic simulator, serving as a testing tool for integration in the traffic module of the SCANeR Studio T M simulation software. The algorithm will bring more natural interactions between vehicles in simulation and allow the emergence of new relevant situations for autonomous vehicles, observable in real, such as collision risk situations or even accidents, which have for now to be scripted in sce…
Traffic proximity and lung function. A case-control study in asthmatic children
2015
Introduction: Respiratory conditions are strongly dependent on air pollution. Urban areas are typically characterized by risky environmental conditions. Objectives: To analyze the effect of traffic proximity on asthma and to explore the relationship between level of traffic proximity and lung function in asthmatic and non- asthmatic children. Methods: A case-control study on children visited for suspected respiratory diseases at IBIM from 2011 to 2014 was performed. All the children have been geocoded according to their residence address. Exposure to traffic air pollution was assessed through determination of number and types of streets in proximity of the place of residence. The relationsh…
Il traffico illecito di droghe leggere dal Mediterraneo all'Atlantico: punti fermi e questioni aperte
2019
Il saggio analizza il tema del controllo penale delle di droghe leggere, con particolare riferimento al contesto geografico del bacino del Mediterraneo. Combinando i risultati della ricerca criminologica con quelli l'analisi dei sistemi normativi di Italia, Spagna, Portogallo, Grecia e Germania, lo studio prende in considerazione pregi e difetti dei modelli normativi "antiproibizionisti" sia alla stregua degli argomenti di principio che possono essere richiamati a sostegno o contro la prospettiva di legalizzazione della cannabis e delle altre droghe leggere, sia con riguardo agli effetti che l'adozione di tali modelli potrebbe generare sul versante del contrasto al crimine organizzato.

Sistema penale e fenomeno migratorio
2018
Molteplici sono gli spazi di intervento penale nel contesto del fenomeno migratorio; plurime e diversificate le sue funzioni. L’ordinamento può servirsi dello strumento penale per tutelare l’interesse dello Stato a regolamentare i propri confini. Alcune fattispecie penali incriminano il migrante che entra o soggiorna irregolarmente nel territorio o che vi fa ritorno dopo essere stato espulso. Altre sono dirette alla repressione di coloro che favoriscono l’immigrazione illegale: si tratta dei “trafficanti di migranti”, ma anche di tutti i soggetti che procurano in qualsiasi modo l’ingresso illegale nel territorio dello Stato. In quest’ultima ipotesi, diviene molto controversa l’incriminazion…
