A demand-based methodology for planning the bus network of a small or medium town.

2010

This work aims at developing a demand-based methodology for designing the bus network of a small or medium town. The proposed modelling tool adopts a multi-agent objective function which evaluates performance in the context of different stakeholders: the surplus of travellers (car and bus users); the bus service provider’s revenues and operation costs. This approach was applied to an existing bus network, serving city of Trapani, which is a medium town in the south of Italy (Sicily), with 100000 inhabitants. The bus-based public transport system attracts only about 5% of commuter trips within Trapani (source: National Institute of Statistics, 2005). This paper reports on an analysis of the …

RESTRICTIONS ON REGIONAL PASSENGER TRANSPORT DURING EPIDEMIOLOGICAL THREAT (COVID-19) – AN EXAMPLE OF THE LOWER SILESIAN VOIVODSHIP IN POLAND

2020

The beginning of 2020 was associated with the appearance of the global coronavirus pandemic (COVID-19). The spread of the epidemic caused the introduction of an epidemiological emergency in Poland in early March (on March 12). This resulted in reduced public transport, including regional rail transport. In Lower Silesia, this concerned regional and fast connections. The conducted analysis concerns regional connections and is based on exploration of the spatial and the quantitative aspect of these changes. The transport offer before and after the announcing of the epidemic was analysed. The results showed that most of the transport restrictions concerned the peripheries of the voivodeship (l…

Experimental and CFD evaluation of ozone efficacy against coronavirus and enteric virus contamination on public transport surfaces

2021

The limited information about the routes of the transmission of SARS-CoV-2 within the ongoing pandemic scenario mobilized the administration, industry and academy to develop sanitation and disinfection systems for public and private spaces. Ozone has been proposed as an effective disinfection method against enveloped and non-enveloped viruses, including viruses with similar morphology to SARS-CoV-2. Due to this efficacy, numerous gaseous and aqueous phase ozone applications have emerged potentially to inhibit virus persistence in aerosols, surfaces, and water. In this work, a numerical model, a RANS CFD model for ozone dispersion inside tram and underground coach has been developed includin…

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…

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…

Sistemi di trasporto pubblico urbano via mare. Un modo per rilanciare il waterfront di Palermo

2011

New sea transport terminals can be major people movers and main centres for various urban activities and functions, determining strong social output. The city of Palermo qualifies as a prominent research territory, due to its densely urbanized and populated waterfront areas, associated with a lack of transport infrastructures and efficient transit systems to meet the mobility demand of residents and commuters. A new waterfront arrangement can improve the city image and opens the way to new urban public transport systems by sea, like ferries and hydrofoils, as an alternative to the conventional land transit systems already affected by unavoidable congestion. Plans to link by sea different de…

Il reporting per segmenti nei settori del trasporto pubblico locale e della cura della salute. Esperienze a confronto.

2020

This paper examines issues of cost and revenue allocation that arise when segment reporting is carried out in local public transportation and healthcare companies. It also presents reports by segment schemes that can be used by companies operating in the aforementioned sectors. The research was carried out with the qualitative methods of participant observation and document analysis. this study focuses on the-oretical principles that have been derived from experiences carried out in the design and implementation of a segment reporting system in two companies operating in the public transportation and healthcare sectors. The analysis of the issues and solu-tions adopted by the companies obse…

The Role of the Integrated Public Transport Network for Reducing the Congestion in the City of Palermo

2019

The railway link of Palermo is part of the Palermo – Trapani railway line and it is located in the urban site of Palermo. Works funded by the European Union have been started in 2008 for developing a metropolitan service through the improvement of the infrastructure and of the transport service characteristics. The aim of the paper is the analysis of the capacity of the railway infrastructure in terms of frequency and integration with the public transport service of Palermo. Using the Origin-Destination matrix of the Urban Transport Plan of Palermo, the competition between the private car mode and the public transport mode has been simulated, taking into account the improving of the railway…
