No full textUrban Transport system monitoring: the black points problem
No full textThe “European road safety Action Programme – halving the number of road accident victims in the European Union by 2010: a shared responsability” (Bruxelles – 02.06.2003) says that every year in Europe 1.300.000 road accidents cause more than 40.000 deaths and 1.700.000 injured. Direct and indirect costs due to such a problem have been evaluated 160.000.000 euros, that is 2% of EU GNP. In the same program they complain about the difficulties of solving the problem, especially at urban scale. Our research underlines the most important contents of the Italian “guidelines for urban road safety plans”. This study at least wants to suggest an innovative methodology to analyze and control road safety, with particular reference to the “black points” of urban road infrastructure, to prevent and reduce the incident risk. The application of opportune methodologies and the continuous monitoring action of the results represent the correct strategy to solve the problem of road safety that, in accordance with the European Directive, has to be considered as a “value” and as a “performance indicator”

No full textIn this paper the problem of understanding the potentialities, the strengthens and the weakness of freight transportation intermodality, is addressed. To do so, first the European policy for promoting intermodality, and in particular the modal shift towards more sustainable transportation modes are described. Then, after a discussion of the state-of-the-art of combined transportation, the cost of intermodality are described, pointing out the effect of modal change on costs.
In the end, a description of innovative methodologies and systems for mode change are described, aiming to point put the relevant effectiveness in time and cost reductions

No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Travel time, operating and total cost: comparison between Tuscan trucked air cargo and an environmentally sustainable intermodal freight system
No full textWith the help of case study, the present research tries to show that a certain new freight intermodal system can be a good solution only if it is accepted by transport operators. Therefore the system has to be sustainable from the point of view time and cost. The first step of the research intends to identify the Tuscan Industrial Zones (Italy) characterized by an important air cargo export, to define the destination airports, to give a graphic description about ways that they are linked and to determinate current travel time and operating costs. It also introduces a project suggestion concerning a new intermodal system called “Metrocargo” which realizes a rapid road-railway modal exchange, evaluating travel times and operating costs relating to the regional railways lines that link the demand origin and the destination points.
The second step intends to quantify the time monetary value both in the event of trucked air cargo and in the event of rail transport, so as to define the total costs
