Pathways and pedestrian crossings: indicators of quality and safety

2014

Pedestrian mobility can be considered an important feature in a new model of town organization. Enhancing pedestrian mobility could bring new life and activities in the old and historic parts of the town reviving their original identities. The planning of new quarters is often performed considering a wide use of private cars, this resulting in urban highways and long and winding local roads hindering pedestrian mobility and safe-ty. Town social features and mobility purpose, related to pedestrian age, are important elements to define the Pedestrian Safety Indicators. Using a GIS software, an evaluation of risk was carried out along a main urban road in order to study and develop measures to…

STATBOX Concept for Simulation of Urban Phenomena

2013

Abstract An urban environment is a dynamic system which is constantly changing in terms of space and time. There are two dimensions in any urban environment – the physical dimension and the functional dimension. All of the structures of an urban environment interact and people are the intermediaries in this process. The spatial structure of cities has been studied from various perspectives by architects, urban planners, environmental scientists, economists, geographers etc. Constant monitoring that is based on remote sensing, spatial statistics, simulation etc., is needed to make on going note of transformation in the various types of land use that exist, movement of people and business env…

Are Red Lists really useful for plant conservation? The New Red List of the Italian Flora in the perspective of national conservation policies

2013

La nuova Lista Rossa della flora Italiana comprende tutte le "policy" specie italiane e altre specie di nota conservazione e comprende 400 taxa di cui il 65% sono minacciate di estinzione. La Lista Rossa si basa su un enorme data-set georeferenziato utile per gli scopi di conservazione. - The New Red List of the Italian Flora includes all the Italian policy species and other species of known conservation concerns for a total of 400 taxa, 65% of which are threatened with extinction. The Red List is based on a huge georeferenced data-set useful for conservation purposes. -

Shadowing e GIS qualitativo: due strumenti per narrare la città

2015

Questo breve articolo descrive la città attraverso due tecniche di ricerca qualitativa (lo shadowing e il GIS qualitativo). Partendo da alcuni esempi, tratti dall’esperienza sul campo, vengono valutati limiti e possibilità delle tecniche in oggetto. L’obiettivo è quello di argomentare la necessità di utilizzare e sviluppare nuovi strumenti metodologici per conoscere le configurazioni urbane. Gli autori sostengono il bisogno di muoversi all’interno di un orizzonte interdisciplinare e di utilizzare tecniche capaci di far emergere narrazioni polifoniche della città. Analizzando le potenzialità dialogiche dello shadowing e le potenzialità sovversive dei GIS qualitativi, una cartografia capace d…

Integreating geological and seismological data in point process models for seismical analysis

2017

Nowadays in the seismic and geological fields, large and complex data sets are available. This information is a valuable source that can be used for improving the seismic hazard assessment of a given region. In particular, the integration of geologic variables into point process models to study seismic pattern is an open research field that has not been fully explored. In this work, we present several open-access datasets (the catalogue of the earthquakes, geological information such as faults, plate boundary and the presence of volcanoes) that are properly treated to describe the seismicity of events occurred in Greece between 2005 and 2014. We use these datasets to fit an advanced spatial…

A regional GIS-based model for reconstructing natural monthly streamflow series at ungauged sites

2016

Several hydrologic applications require reliable estimates of monthly runoff in river basins to face the widespread lack of data, both in time and in space. The main aim of this work is to propose a regional model for the estimation of monthly natural runoff series at ungauged sites, analyzing its applicability, reliability and limitations. A GIS (Geographic Information System) based model is here developed and applied to the entire region of Sicily (Italy). The core of this tool is a regional model for the estimation of monthly natural runoff series, based on a simple modelling structure, consisting of a regression based rainfall-runoff model with only four parameters. The monthly runoff i…

L’opposizione alto/basso nella toponomastica dell’area subalpina

2015

Il contributo proposto esamina la presenza e la distribuzione di alcune serie toponimiche correlate ai concetti ‘alto’ e ‘basso’ sul territorio piemontese, cercando di evidenziare le possibili valenze a livello denotativo e connotativo. Le risorse offerte dal sistema ToP-GIS, elaborato all’interno del Centro Studi di Onomastica dell’Università di Torino, permettono un sistematico rilevamento dei dati e una lettura del territorio su più piani; nell’interpretazione del sistema si è adottata una prospettiva diacronica, illustrando le forme toponomastiche riconducibili a realtà linguistiche prelatine e a varietà romanze diverse dall’italiano. Insistendo sulle tracce medievali, si evidenzia inol…
