The analysis of urban travellers’ latent preferences to explain their mode choice behaviour
2012
Our research aims to explore the impact of latent variables, mirroring urban travellers’ attitudes and perceptions, on the individual decision making process regarding the mode of transport. The paper describes the first results of an ongoing research activity, which derive from a pilot study conducted in Palermo, the capital of the Sicilian Region (in the south of Italy), and demonstrate that policy makers, in designing a socially desirable and environmentally sustainable urban mobility system, should take into account how travellers perceive the qualitative dimensions of transport.
L'accessibilità al trasporto pubblico locale: il caso studio dell'area Roccella in Palermo

Aspects regarding the appreciation of regularity and punctuality in the public transport system from Sibiu, Romania
2021
Regularity and punctuality are two very important measures for evaluating the quality of a public transport system. Several indicators can be used to estimate them, each with advantages and disadvantages. The paper comparatively describes a series of such indicators and presents a study conducted for two public transport lines in Sibiu, Romania. The study shows how, depending on the indicators used, the results show the influence of different factors.
Bus Speed Estimation By Neural Networks To Improve The Automatic Fleet Management
2007
In the urban areas, public transport service interacts with the private mobility. Moreover, on each link of the urban public transport network, the bus speed is affected by a high variability over time. It depends on the congestion level and the presence of bus way or no. The scheduling reliability of the public transport service is crucial to increase attractiveness against private car use. A comparison between a Radial Basis Function network (RBF) and Multi layer Merceptron (MLP) was carried out to estimate the average speed, analysing the dynamic bus location data achieved by an AVMS (Automatic Vehicle Monitoring System). Collected data concern bus location, geometrical parameters and tr…
University campuses as small-scale models of cities: Quantitative assessment of a low carbon transition path
2019
Abstract The energy efficiency interventions and rehabilitation actions regarding university campuses are characterized by an emblematic impact, representing significant examples of good practices that a given community could adopt, even at the city level. Starting from the idea that campuses may be regarded as small scale models of cities, a quantitative method for estimating to which extent the adoption of a given set of interventions by a municipality could contribute to make such city close to a nearly zero energy profile is proposed. To accomplish this task, the study considers the low carbon transition path of the campus of the University of Palermo and applies a simple method that, i…
Pedestrian Safety Indicators Study
2008
Pedestrian mobility can be considered an important feature in a new model of town organization, being suitable for the newly urbanized areas as well as the old quarters and the outskirts, places where streets and squares, once devised for a pedestrian based mobility, were eventually overcame by an ever increasing motorized traffic. Enhancing pedestrian mobility could bring new life and activities into the old and historic parts of the town reviving their original identities. The last decade’s increase in the recourse to private cars requires improvements in pedestrian mobility quality. This can be achieved by building new infrastructures, limiting the use of private cars, improving public t…
Understanding the Key Factors of Shared Mobility Services: Palermo as a Case Study
2020
The potential success of shared mobility services in the urban area strongly depends on careful tariff planning, adequate sizing of the fleet and efficient integrated public transport system, as well as on the application of policies in favor of sustainable modes of transport. The balance between earnings and expenses is not always an easy target for the companies in those cities where these services are not well-rooted in the citizens’ mobility habits. Often only large operators in the sector can continue to offer a service generating profit. However, several factors can determine the success or the failure of shared mobility services. The objective of this study is to identify, thanks to …
MODELLING THE ACCESSIBILITY TO PUBLIC LOCAL TRANSPORT FOR INCREASING THE EFFICIENCY AND THE EFFECTIVENESS OF THE SERVICE. THE CASE STUDY OF ROCCELLA …
2013
This paper suggests a methodology to assess, through quantitative indicators, the public transport based accessibility inside an urban area. Such indicators derive from two functions, one called “activity function”, allowing for the presence of generators and attractors of mobility and another termed the “impedance function”, measuring the generalized cost of public transport journeys. The proposed method was tested and applied to a zone on the outskirts of Palermo (capital of the Sicilian Region), to evaluate the effects of a new tram line, which is under construction and will be activated by the end of 2012. The study shows that such a line is not sufficient to enhance significantly the a…
Pedestrian access to a network of public transport
2011
The location of the bus stops is very important in urban and suburban contexts. The same importance of safety perception and comfort during transport operations is attributed to accessibility to bus stops. The placement of bus stops is a crucial factor to increase safety of passengers and pedestrians as well as the efficacy and efficiency of local public transport operations. To correctly localize these infrastructures, designers use physical parameters, such as maximum walking distance and travel time. While critical factors related to the quality of pedestrian access to the bus stop, to the real walked distance or to land use of bus stop areas are not taken in to account. The purpose of t…
SUSTAINABLE URBAN PUBLIC TRANSPORT. A COMPARISON BETWEEN EUROPEAN AND NORTH AFRICAN CITIES
2011
The aim of paper is to carry out a benchmarking analysis among European and North African Cities in order to point out the improvement areas for a Sustainable Urban Public Transport System. The focus is to improve public transport performance, all aspects such as fares, operational effectiveness and attractiveness of the service.
