No full textTransport management and land-use effects in presence of unusual demand
No full textThis book contains a selection of the papers presented during the Scientific Seminar 2009 of the Italian Society of Transportation Scholars (SIDT) organized within the annual international conference of the Society, which took place in Milan.
The theme of the conference was "The effects of important events on land-use and transport" and it was stimulated by two forthcoming related events: the "Forum delle Culture", Naples, 2013 and notably the "Expo", Milan, 2015.
Selected paper focus on mathematical models and techniques for transport management and land-use effects in the presence of unusual demand, including some case studies.
This is the first book of SIDT proceedings produced in English in order to introduce SIDT activities to the international community.
Selected papers are a part of the research activities carried out by SIDT members, representing all the Italian university professors and researchers who study and teach topics in transportation, and contributing to the community debate on transport systems and related topics, such as land-use, economics, environment and energy in order to support worldwide efforts for a sustainable development

Una Indagine Sperimentale sulla Relazione tra Incidenti, Caratteristiche Geometriche e Condizioni Operative sulla Viabilità Urbana
No full textLe metodologie per l'analisi della sicurezza stradale sono allo stato dell'arte molteplici e, nel corso degli ultimi anni, sono state implementate in alcuni casi grazie alla disponibilità di database sufficientemente significativi per numerosità, precisione e affidabilità dei campioni di dati, in altri casi grazie alle potenzialità offerte da algoritmi di calcolo sempre più sofisticati. In questo scenario si collocano numerosi approcci (reti neurali e bayesiane, distribuzioni di Poisson e binomiale negativa) come ampiamente trattato dalla letteratura specialistic
On the velocity distribution at equilibrium in the mathematical theory of vehicular traffic flow
No full textAbstractThis work deals with a two-scale vehicular traffic model, where the mass conservation equation is closed by a velocity probability distribution, parameterized with respect to each density of vehicles. The above probability distribution is identified on the basis of both experimental information and theoretical conjectures
Novel centrality measures and applications to underground networks
Full text linkTwo novel centrality indices, PathRank and Icentr, are defined. PathRank is a generalization of the PageRank algorithm, suitable to rank nodes of undirected graphs according to number and weight of paths in the graph. Icentr ranks the nodes of the graph by means of a combination of the weights of nodes and edges, scaled according to the distance from each node, one at a time. We apply the two novel indices to underground transportation networks, since these networks represent an infrastructural backbone for the transportation system of most big cities over the world. The characterization of the most important components of those networks and the simulation of their responses when they stop working properly, are vital for maintaining the mobility service at a desirable level. Since there are different ways to associate a graph to an underground network according to the degree of detail and aims of the study, we describe the methodology we adopted to associate a graph to such a network. The methodology was applied to 34 underground networks of worldwide cities, and the resulting graphs constitute the reference dataset. A detailed study of both Boston network and the dataset is proposed as prototypal for either a graph alone or all graphs in a dataset. Results show how different features of graphs are revealed by the two novel indices
