A metthological approach to optimize the practice capacity of railway junctions

2006

The practice capacity of a railway junction depends, in addition to the effective operation’s conditions, by the potential risk factors tied with the design characteristics of the railway station. With the aim of an approach based on the “fuzzy sets” it is possible to determine the numeric value of the practice capacity by the logic – qualitative relations between the features of the railway junction and the potential risk factors. This methodology permits to try out the absolute value of a suitable vector β, (less then the unit) for the utilization of the theoretic capacity in conditions of maximum reliability of the system related to the aspect of safety (technique “fail safe”).

A behavioural model to evaluate the delay on urban traffic flows and analysis of environmental implications

2014

This paper deals the problem of a road's capacity in presence of perturbations in the vehicular flow. In particular, among the different causes of delay, is here the presence of vehicles parked along the road in relation at their parking activity. Preliminarily is evaluated the delay, caused by each vehicle that leaves its parking position and enters in the traffic flow or by that who slows down the flow to enter in the parking, by introducing these effects in the equations of flow, it is possible to evaluate the modifications that the same curves of down flow suffer. Consequently, it is also possible to evaluate the increase of pollutant emissions.

Performance Analysis of Basic Turbo-Roundabouts in Urban Context

2012

AbstractA turbo roundabout is a new type of canalized multilane intersection in which the physical separation between lanes helps to prevent side collisions when crossing the roundabout. This paper presents an estimation of capacity, delays and level of service of basic turbo roundabouts in undersaturation conditions, considering both vehicle flow and pedestrian traffic. The traffic performance model was developed by evaluating the capacity for each entry lane. Owing to the geometric features of the intersection, the total entry capacity is obtained by considering different values of the pedestrian impedance factor and degree of saturation at both the right-turn and left-turn lanes.

A LOGISTICS PATTERN FOR FRUIT AND VEGETABLE TRANSPORTATION FROM ISLAND REGION: THE CASE OF SICILY

2014

The globalization of markets regards many sectors in the E.U. and among them also the fruit and vegetable in the face of growing and increasingly intense competition exerted by the products of countries with emerging economies. But, at the same time, the globalization can also lead to the opening of new potential markets for the products, when and where the transport system, more than other things, appears to be efficient and effective and makes possible to reach the target markets in the shortest time possible and at the lowest possible cost. It is therefore very useful to create a model that takes into account hepeculiarities of the different modes of transport between the different origi…

Tramway Track: A New Approach for Measuring the Transverse Profile of Worn-Out Rails

2012

Abstract Monitoring the wear condition of the tramway superstructure is one of the key points to guarantee an adequate safety level of the light rail transport system. The purpose of this paper is to suggest a new non-conventionalprocedure for measuring the transverse profile of rails in operation by means of image-processing technique. This methodological approach is based on the “information” contained in high-resolution photographic images of tracks and on specific algorithms which allow to obtain the exact geometric profile of the rails and therefore to measure the state of the rail-head extrados wear.

Estimation of Measures of Effectiveness (MOE) for the C-Roundabouts

2013

The C-roundabout (cyclist roundabout) is a new multi-lane roundabout designed to improve the safety of cyclists at and make multi-lane roundabouts more cyclist-friendly. The geometric layout of C-Roundabouts allows the decrease of the vehicle speeds through the roundabout to around 30 km/h. The rare C-roundabout installations so far implemented in the world have not allowed analysing the capacity by means empirical data. In the light of this considerations, the main objective of the paper is to give a theoretical closed-form model for evaluation the measures of effectiveness MOE (capacity, delay, queues) of the C-Roundabouts.

Flower roundabouts: estimation of capacity and level of service

2012

The research work on road junction geometry, carried out in European research centres, has recently allowed to design new road intersection types which are of undoubted interest, especially in terms of traffic functionality and safety. Among the most interesting solutions there are such schemes as spiral, turbo and flower roundabouts, which are similar to traditional roundabouts. Although these solutions provide a traffic travels counterclockwise around a central island and in which entering traffic must yield to circulating traffic, the newly designed schemes generally offer modes of traffic flow regulations which highly differ from those used in conventional roundabouts. Of considerable i…

The Rail Quality Index as an Indicator of the “Global Comfort” in Optimizing Safety, Quality and Efficiency in Railway Rails

2012

AbstractThe proposed model uses the stochastic dynamic programming and in particular Markov decision processes applied to the Rail Quality Index (RQI - Italian Indice di Qualità del Binario, IQB).By performing the integrated analysis of the classes of variables which characterize the overall service quality (in terms of comfort and safety), the proposed mathematical approach allows to find the solutions to the decision-making process in function of the probability of deterioration of the state variables of the infrastructure over time and of the flow of available resources.

Turbo roundabouts:geometric design parameters and performance analysis

2012

A turbo roundabout is a particular type of roundabout where entering and circulating lanes are bounded by traffic signs and by non-mountable curbs. The physical separation between lanes, both at entries and on the ring, helps to prevent side collisions crossing the roundabout. The main advantages of turbo roundabouts are: i) reduction in the number of potential conflict points; ii) lower speed of vehicles passing through the intersection; iii) safety conditions at the intersection due to lower risk of side-by-side accidents. Also, in some cases the capacities of turbo roundabouts are higher than the capacities of conventional roundabouts. This paper presents an estimation of capacity, delay…

Riciclaggio resodui del marmo - L'uso del "ravaneto" nelle costruzioni stradali

2007

L’importanza economica dell’attività di estrazione e lavorazione dei materiali lapidei di pregio, ha segnatamente marcato lo sviluppo territoriale di aree della regione Sicilia concentrate per lo più nelle due province di Trapani e Catania. Alla elevata quantità estratta non ha corrisposto però una adeguata strategia di pianificazione per la salvaguardia ambientale specificatamente connessa ai materiali inerti da impiegare nel settore delle costruzioni. Infatti, sebbene l’estrazione dei materiali lapidei di pregio genera quantità di materie residuali per lo più non utilizzate pari a circa il 70-80 % del totale estratto, ancora oggi vengono coltivate cave di inerti per l’impiego nel settore …

Improving the sustainability of transportation: environmental and functional benefits of right-turn by pass lanes at roundabouts

2015

The functional performances of conventional roundabouts (single-lane and multi-lane) and innovative roundabouts (spiral, flower, C and turbo) can be improved through right-turn bypass lanes controlled by stop, yield or free-flow signs. The article presents evaluations of the emissions of air pollutants (carbon dioxide, nitrogen oxides, particle pollution (PM10 and PM2.5)), fuel consumption and construction, management, energetic and environmental costs in roundabouts without or with bypass lanes (controlled by stop, yield or free-flow). The suggested methodology has a general character and can be applied as a multi-parametric criterion for choosing road intersections, although, in the prese…

Le attività di ricerca inerenti la geometria dei nodi viari, svolte soprattutto in Enti di ricerca europei, in tempi relativamente recenti hanno consentito di ideare nuove tipologie di intersezioni stradali che presentano un indubbio interesse, soprattutto in termini di funzionalità e di sicurezza della circolazione. Tra le soluzioni più interessanti si annoverano gli schemi affini alle tradizionali rotatorie come ad esempio le rotatorie a spirale, le turbo rotatorie e le rotatorie a fiore. Pur trattandosi di soluzioni con circolazione rotatoria, in genere negli schemi di nuova concezione le modalità di regolamentazione dei flussi veicolari risultano assai diverse rispetto a quanto avviene …

Characterization of Biodiesel from Vegetable Oil Using Comprehensive Two-Dimensional Gas Chromatography

2012

Biodiesel from vegetable oils has been analyzed and its suitability for internal combustion engines has been assessed. The Standard biofuel’s characteristics have been investigated. Gas chromatography (GC) tests were carried out to characterize the fatty acid behavior. It was found that the mass percentage of saturated fatty acids did not change substantially with time, while unsaturated fatty acids increased with time for both B100 and B30. An increase in density for B100 and B30 with time was noted. Biodiesel density was within the standardization. The calorific values of biodiesel and its blend increased with time. Higher heating value for B100 increased from 41 to 43 MJ/kg while B30 inc…

A new methodology to estimate deformation of longitudinal safety barriers

2013

The correct sizing of storage areas in the port areas is aimed to optimizing the management of intermodal transport and to ensure efficiency and functionality to the entire port system. In this paper is proposed a simulation model for design the port storage areas taking into account many parameters like: the service time, the randomness of the arrivals process, the storage capacity in terms of TEU that can be stored (and handled) in the unit of time. The capacity of the terminal warehouse is determined by the interrelation between fixed and static parameters in the short period which are: i) the extension of the storage area; ii) the height of the overlapping batteries of container (define…

Environmentally appraising different pavement and construction scenarios: A comparative analysis for a typical local road

2015

Abstract The aim of this work is to carry out a comparative analysis of environmental impacts for different scenarios of a typical local road. Life Cycle Assessment (LCA) is the modeling tool used to quantify and characterize comparative environmental impacts. In carrying out this specific application of the LCA, different road construction techniques were considered with regards to the whole structure and compared in order to identify the best alternative in terms of environmental sustainability. So far, in fact, typical LCA frameworks of roads have focused on recycled materials for pavement layers only, thus neglecting study of the materials used in the embankment or in the subgrade. In t…

Environmental Implications of Traffic Flow Delays: a Model for Urban Streets

2013

In this paper the problem of road's capacity is dealt in presence of perturbations of the vehicular flow. In particular, among the different disturbing causes, it is here considered the presence of vehicles parked along the road in relation to their parking activity. Having already established the delay, caused by those vehicles leaving their stationary positions and entering the traffic flow or by those who slow down the flow to park, it is possible to evaluate the changes in time running values. Related to these times delay, the extra pollutant emissions by a given urban running fleet is also evaluated, by utilizing emission factors depending on age, type, volume capacity and engine of th…

Calculation of Turbo-Roundabouts with Slip Lanes

2013

A turbo roundabout is a particular type of roundabout where all lanes are bounded by traffic signs and by non-mountable curbs installed at entering and circulating lanes. Turbo roundabouts also have a very particular shape to accomplish the splitting of traffic streams and to prevent cars weaving through. These aspects make turbo-roundabouts more appropriate than roundabouts when a higher level of safety has to be guaranteed, particularly in presence of relevant pedestrian and two-wheels traffic volumes. Only in some traffic conditions, turbo roundabouts can offer higher capacities than conventional double-lanes roundabouts, so if more capacity must be guarantee a bypass lane can be added t…

Handling Underdispersion in Calibrating Safety Performance Function at Urban, Four-Leg, Signalized Intersections

2011

Poisson basic assumption of equidispersion is often too much restrictive for crash count data; in fact this type of data has been found to often exhibit overdispersion. Underdispersion has been less commonly observed, and this is the reason why it has been less convenient to model directly than overdispersion. Overdispersion and underdispersion are not the only issues that can be a potential source of error in specifying statistical models and that can lead to biased crash-frequency predictions; these issues can derive from data properties (temporal and spatial correlation, time-varying explanatory variables, etc.) or from methodological approach (omitted variables, functional form selectio…

THE DESIGN OF WAITING AREAS TO OPTIMIZE THE STORAGE CAPACITY IN THE MARINE INTERMODAL TERMINALS

2009

The appropriate sizing of storage areas to optimize the management of intermodal transport, the adoption of environment protection systems and the appropriate flow’s regulations inside manoeuvre’s zones can solve many problems encountered today in a intermodal marine terminal. For these reasons the “integrated design” of storage areas for vehicles and containers is considered essential to ensure efficiency and functionality for all harbour-system. So is here proposed a simulative model as a tool for a more correct design of waiting areas by considering the real stochastic conditions of the process of the arrivals. For the sizing of areas for containers in the harbours, it is necessary to re…
