Variable message signs (VMS) are used to display messages providing up-to-date traffic-relevant information so that drivers can safely adapt their behavior in real time. The information reported in a VMS should be brief but comprehensive to minimize perception time. The latter can be influenced by the way the message is displayed. This study investigates how the different ways of displaying the same message can influence reading time and the information perception process at different driving speeds. Specifically, the following message characteristics are investigated: (i) use of uppercase and lowercase letters; (ii) use of familiar pictograms; and (iii) use of less familiar pictograms. Furthermore, as perception time typically changes with ageing, drivers belonging to three different age classes are tested. The experimentation was performed by simulating a vehicle passing along a straight road upon which a VMS displaying different messages was placed. Experimentation results are analyzed using the Kruskal–Wallis test, Friedman rank-sum test and Welch one-way ANOVA, showing that: (i) the use of uppercase or lowercase does not seem to significantly affect reading times; (ii) the use of pictograms that are not very familiar to habitual road-users can be counterproductive for the perception process; (iii) elderly drivers always have greater difficulty in perceiving the message than young or middle-aged drivers. The findings of this study can be of help for traffic authorities to design the most suitable structure for a VMS so that its information can be unequivocally and immediately conveyed to drivers.

As part of the LIST-PORT, Report and Decibel Project (Interreg IT-FR Marittimo Programme 2014–2020), which is included in a cluster of initiatives aimed at containing port noise, a synchronized traffic - noise survey campaign involving four ports in as many cities in the upper Tyrrhenian area, is now nearing completion. This paper describes the guidelines on the basis of which the traffic-noise surveys were conducted in the four ports and the types of data collected. In a second step of the study, these data will be used to train the predictive model of the sound pressures generated by traffic in ports, based on neural networks. The database presented in this work is thus the key element for the subsequent implementation of the predictive model which is currently in an advanced phase of development as part of another project in the cluster.

The problem of the presence of waste in the marine environment has recently taken on the dimensions of a complex and global challenge. In an effort to reduce both the economic and environmental costs of managing port waste, many ports are looking for sustainable solutions for marine waste management. Plasma-assisted gasification (PAG) is an innovative combination of two technologies, namely plasma treatment and gasification, which can be used to efficiently convert carbon-containing wastes to a clean syngas (H2 + CO). The latter can be used to generate electricity directly in gas engines, dual-fuel generators, gas turbines or fuel cells. PAG provides several key benefits which allow removing all the environmental, regulatory and commercial risks typically associated with the potential eco-toxicity of leachable bottom ash produced by incinerators or other thermal processes. PAG does not produce any waste (zero waste), reduces the need for landfilling of waste, and produces a high-value construction material (Plasmarok) which is recognized as a product. All these reasons make PAG a technology capable of optimally solving waste management in ports in line with a circular economy logic. This study is based upon the IMPATTI-NO Project (Interreg IT-FR Maritime Program 2014–2020) which implements several laboratory applications aimed at the chemical-physical treatment of the non-recyclable waste containing plastics deriving from the collection of beached waste and wastes collected by fishermen’s trawls and passenger ships. To demonstrate the effectiveness of PAG for the treatment of port waste, IMPATTI-NO performs experimental tests that simulate PAG pilot plants using artificial samples representative of port waste. This paper describes the research path developed so far and the preparatory elements that led to the definition of specifications for the sampling and collection of port waste.

This study applies cost benefit analysis (CBA) approaches to evaluate corporate and social profitability of a coordinated management proposal for a Short Sea Shipping (SSS) network in the upper Tyrrhenian area. The profitability of the maritime network is assessed first for the shipping companies operating therein and then for society as a whole. Corporate profitability analysis reveals a supply system currently over-sized compared to actual demand. The reasons for this must be found in the corporate competition strategies that traditionally characterize the free maritime transport market in the area. Social profitability analysis proves the potential positive impact of services rescheduling and coordination in terms of time savings and emission reduction in port areas and demonstrates the benefits new integrated management policies could yield for achieving higher efficiency and sustainability in SSS Tyrrhenian networks.

The 4.0 revolution in the shipping industry is growing fast and ports are requested to constantly innovate and evolve. Ports need to become not only smarter to implement more efficient, sustainable, and safer operations but also interconnected with each other. This paper presents the experience of the Easylog Project – Optimized logistics for ports and intermodal transport – funded under the Interreg IT-FR Maritime 2014–2020 program. Easylog aims to improve the mobility of rolling cargo between Italian and French regions by taking advantage of ICT technologies to increase the performance of intermodal transport chains and the overall quality of the services offered by ports. The project involves five ports in the upper Tyrrhenian area for which it proposes the shared adoption of integrated ICT devices for optimized and secure management of port operations between the operators involved in the cross-border (trans)port chain. The driving idea is to move from a non-integrated and fragmented management and control system of port events and flows to a common and connected ICT system. Easylog may represent a useful case study potentially replicable in many port contexts.

Short Sea Shipping (SSS) is generally considered as a privileged transport mode in terms of reducing road congestion and related external costs. In the last two decades, SSS has attracted a lot of attention in the European Union, where it is also regarded as a key factor for economic and social cohesion between countries. In this regard, the present study proposes a new network design that aims at improving and increasing freight traffic between the north-western and the south-eastern shores of the Mediterranean Basin. The proposed model, designed for Ro-Ro (Roll-on Roll-off) freight transport, tries to overcome the limits of the existing multi-port-calling services through an innovative two-hub-based scheme of better scheduled and reliable frequencies and more competitive delivery times. The operating parameters of the new network are determined using a specially designed optimisation approach based on two separate but related mathematical models: a Mixed Integer Linear Programming Model for Service Frequency Selection and a Mixed Integer Linear Programming Model for Service Timetabling. Numerical tests, performed on real demand and supply data covering 23 ports in 8 Mediterranean countries, show the validity of the proposed approach to determine an optimal network configuration for the organisation of transport services in the area.

Nearly 1.35 million people are killed annually on roads around the world and an additional 50 million are injured or disabled. Road traffic crashes are estimated to be the eighth leading cause of death globally for all age groups, the first among children and young people aged 5-29 years. These numbers highlight the urgency of the road safety issue for all governments and administrations. In their efforts to improve safety, road network managers can benefit from decision support tools able to assist them in monitoring and managing road safety interventions. This paper proposes a DEA-based decision support method to assist urban road safety management practitioners in identifying those roads where the needs to improve safety are the greatest. The method is applied to an Italian urban road network to define a hierarchy of hazardous road locations based on safety conditions. The social cost of accidents is used here for the first time as the only output indicator while the average number of conflict points at intersections and traffic flow are used as inputs. Both Constant Returns to Scale and Variable Returns to Scale DEA models, each oriented to input and output, are used. The comparison of the results makes it possible to identify the DEA model that seems best suited to be used as a decision support tool to advise urban road safety management by enabling a more careful definition of targeted priority lists of interventions.

The issue of distracted driving by the smartphone is of primary importance for road safety. This study discusses the results of a simulated driving experiment that explores the effects of four smartphone usages on driving performance across a range of driver ages and experiences also considering the gender factor. Unlike most similar studies, which mainly focus on a single element at a time (gender influence, specific age group, etc.), the proposed experimental design investigates the extent to which several combinations of factors related to the driver, the driving environment and the specific smartphone usage may affect driving performance. Using ANOVA and ANCOVA it has emerged that: (i) Age seems to significantly affect driving behaviour, older drivers tend to reduce their speed when using smartphones. (ii) Consistently with previous research, the risk of collision increases for all age groups when using smartphones. (iii) Drivers tend to increase their speed during a phone conversation. This interesting result may indicate how much the perception of risk associated with smartphone use has changed alarmingly in short time. Outcomes provide new knowledge based on experimental evidence and can support legislators towards introducing effective measures to counteract the widespread use of the phone when driving.

Over the past few years, the reduction of maritime emissions has been receiving increasing attention in the shipping industry. The main reason lies in the growing need to reduce global emissions and the fact that, despite its overall environmentally friendly reputation, maritime transport is expected to further increase its contribution to pollution in the years to come. Not surprisingly, there is a growing interest in measures, policies, and initiatives aimed at reducing the carbon footprint of shipping activities. In this regard, the present study aims to investigate the potential role of network design measures in helping to mitigate the environmental impact of maritime transport chains. As far as the authors are aware, no previous studies on measures and initiatives for reducing maritime emissions have focused on the role of network design interventions. This study examines an innovative two-hub based Ro-Ro freight network for shipping services between the north-western and south-eastern Mediterranean shores and uses an activity-based methodology to assess its environmental impact and compare it with the existing system of regular Ro-Ro connections in the area. Numerical results confirm the potential effectiveness of network design measures in reducing the emissions of Mediterranean transport chains and provide new insights for the future development of more effective tactical-operational solutions, based on services integration, to support the adoption of more sustainable transport schemes in the Mediterranean area.

The Initial Strategy on reduction of greenhouse gas (GHG) emissions from ships adopted by the International Maritime Organization (IMO) in 2018 commits the IMO to reduce total GHG emissions of shipping by at least 50% by 2050. Though the direction of the Strategy is clear, the path to implementation remains uncertain. The ambitious IMO’s target calls for widespread uptake of lower and zero-carbon fuels, in addition to other energy efficiency measures, including operational and market ones. Using a triangulated research approach, this paper provides a critical overview of the main measures and initiatives the shipping industry can adopt to try to cope with the new IMO’s requirements. The pros and cons of the most popular emission reduction options are investigated along with the main challenges and barriers to implementation and the potential facilitators that could foster a wider application. The framework that is outlined is complex and not without controversy. Research can play a key role as a facilitator of shipping’s decarbonization by providing its contribution to overcoming the existing controversies on various decarbonization options and by developing a wealth of knowledge that can encourage the implementation of low-carbon initiatives.

In recent years, the analysis of driving behaviour for professional drivers has attracted growing interest from transport operators. This is also witnessed by the importance the recently introduced Driver Qualification Card gives to human factors and the need drivers undergo proper training activities aimed at improving the performance of transport systems both in operational (speed, frequency, reliability, etc.) and safety terms. By discussing the results of an experimental study on driving behaviour involving professional bus drivers, this paper investigates whether any correlations exist between a number of driver characteristics (a.o., age, body weight and driving experience) and the perceived level of discomfort when driving. Analysis of the data performed using Multiple Correspondences Analysis (MCA) shows that a correlation does exist between the perceived level of discomfort in a set of body areas and the age and body weight of the driver.

The aim of this paper is to propose a methodology for identifying the most critical road sections in urban networks in terms of road safety. This approach is useful for the managers of the road network when they need to allocate limited financial resources to several critical sections. Since the resources are not always sufficient to solve all road safety issues, they require a methodology that is able to rank the critical sections. Road safety depends on the interaction of several factors so this methodology has to be based on a multicriteria approach. In earlier articles, the authors of this paper first adopted Electre III and later Concordance Analysis as multicriteria methods for ranking critical points in an urban road network. Both methods have some critical elements, associated with threshold choice (Electre III) and ranking procedure (Concordance Analysis). In order to improve the methodology, the authors have selected two further multicriteria methods (Vikor and Topsis), for comparison with the Concordance Analysis and for evaluating which performed best. In order to identify critical sections in a road network, a suitable set of indicators is defined, taking into account geometric and traffic volume criteria. The multicriteria methods are applied to a real case for ranking, from the worst safety conditions to the best, the most critical road intersections within the urban road network, on the basis of eight criteria. The results of all three methods considered are compared and a sensitivity analysis is performed to test the stability of the results. The results show that the Topsis method performs best in determining a complete ranking of the critical road sections, overcoming some negative aspects associated with the other methods.

Due to the motivations of climate change, the health impacts of poor air quality, and the importance of cities for economic growth, transport policy at all levels of governance places emphasis on reducing and managing urban traffic and congestion. Whilst the majority of urban traffic is created by personal travel, freight vehicles make a relatively large contribution per vehicle to congestion, pollution and severe accidents. The European Commission (EC 2011) estimates that 6% of all EU transport carbon emissions are from urban freight. For these reasons, a well-structured portfolio of measures and policies oriented towards more sustainable and efficient management of supply chain activities carried out in urban areas is needed, in order to reduce negative externalities related to urban mobility and improve economic performance. In recent years, there has been enthusiasm amongst commentators that shared-resource economic models can both create new commercial opportunities and address policy problems, including in the transport sector. Within the city logistics subsector, this new model is exemplified by the emergence of Urban freight Consolidation Centres (UCCs). UCCs replace multiple ‘last-mile’ delivery movements, many of which involving small consignments, by a common receiving point (the consolidation centre), normally on the periphery of a city, with the final part of the delivery being shared by the consignments in a small freight vehicle. Such arrangements can represent a good compromise between the needs of city centre businesses and their customers on the one hand (i.e. high availability of a range of goods) and local and global sustainability objectives on the other. At the same time, by sharing logistics facilities and delivery vehicles, UCCs offer added-value services to both urban economic actors, such as retailers, and network logistics providers. However, UCCs add to the complexity of logistics chains, requiring additional contracts, communications and movement stages. These arrangements also introduce additional actors within the supply of delivery services, notably local authorities present as promoters and funders, rather than simply as regulators, companies specialised in the UCC operation, and companies, which provide specialist technologies, such as electric delivery vehicles. UCCs therefore also represent an example of multi-stakeholder collaboration. Drawing on the results of a 2013 survey in Bristol (United Kingdom) and a further survey carried out in 2015 in Cagliari (Italy), the present paper will provide an in-depth comparison of the differences in the perceptions of urban freight users and stakeholders towards UCCs. Retailers involved in the survey carried out in Bristol showed high satisfaction with the delivery service provided by the UCC. Different topic areas (e.g. timeliness, reliability, safety) are examined through analyses of both qualitative and quantitative data. The survey carried out in Cagliari investigated the inclination of potential users to join a UCC scheme. The comparison between the two cities considers factors such as the nature of business holding (e.g. SME versus multiple retailers), operational practices (e.g. pattern of deliveries) and operating subsector (e.g. food versus no food). An analysis on the barriers to the implementation of UCCs in Bristol and in Cagliari is provided at the end of the paper.

Over the last twenty years, the intensification of trade flows and the rapid growth of demand for goods and services from new emerging countries have led to a deep change in global transport and a dramatic increase in the level of competitiveness among transportation and logistics service providers. To remain competitive, transport and logistics operators are required to carry out operations with maximum efficiency to meet the requirements of a continually growing and diversified demand. Supply Chain Management is one of the areas that have recently attracted much attention in logistics. The proposed study aims to provide simple quantitative tools based on Key Performance Indicators (KPIs) to support the evaluation process of intermodal supply chains. A sample of 44 real-world Mediterranean supply chains has been collected and analyzed. Four quantitative KPIs describing the relationship time-cost and the ratio cost/kilometer have been derived from empirical cost functions and used to characterize the various elements of the analyzed transport chains, and of the chains as a whole, from a cost perspective.

This study aims to investigate the existence of possible changes in postural strategies adopted by quay crane operators during a 4-h shift performed in a simulated environment. In particular, the analysis is carried out by analyzing the trend of in-chair-movement (ICM) as indicator of discomfort and fatigue. Using a pressure sensitive mat placed on the seat pan, average and peak body-seat pressure and trunk center-of-pressure (COP) time series were acquired and processed to calculate ICMs with two methods based on pressure changes and one which considers the COP shifts. The results show a well-defined linear trend for ICM, which was detected by all the tested approaches, with significant increases occurring after 45–60 min from the beginning of the shift. However, the method which employs COP data appears potentially more adequate to accurately identify ICM due to its relative insensitivity to external factors associated with individual’s anthropometry and body composition and presence of external vibrations. Future developments of the study will be focused on establishing the suitability of the method as non-invasive early predictor of fatigue.

This study investigated changes in task-induced trunk sway of quay crane operators during a four-hour shift performed in a dedicated simulator as an indicator of postural control system effectiveness. Using a pressure sensitive mat placed on the seat pan, center-of-pressure (COP) time series were acquired and processed to calculate sway area, path length and COP displacements and velocities. The results show a well-defined linear trend for sway path and area, with significant increases starting from 65 to 155 min of work respectively. This indicates non-optimized trunk control most likely originated by the combination of physical and cognitive workload and suggests a possible role of long-term monitoring of trunk sway of crane operators as a useful tool in detecting non-optimized movements potentially associated with deteriorating performance.

For several years now increasingly analytical prediction models have been developed that are able to correlate accident frequency with infrastructure characteristics to support the planning and design of measures for enhancing road safety. The models developed so far, though useful in the context for which they have been calibrated, are limited by the fact that they are not transferable to other contexts because of different traffic regulations. The present work aims to develop a predictive model for urban roads that is able to estimate the number of accidents for three situations in an urban road network, a roundabout, a three- or four-way junction, and a straight stretch of road. The models constructed are based on Poisson's and negative binomial algorithms and can be readily applied for accident prediction or identification of black spots.

During the last decades, reverse logistics and reuse of products have received growing attention as profitable and sustainable business strategies. Looking at the agrifood distribution sector, every day thousands of agrifood stores throw away large quantities of food product no longer suitable for sale. This "waste product", in the majority of cases, could still find new uses as animal feed or fertilizer. The return flow of food product is a typical problem of reverse logistics. This study proposes a new bi-modular scheme for managing the process of collection of "food waste" resulting from the agribusiness distribution sector and its subsequent distribution to livestock farms and collection centers located in the area of interest. The proposed management scheme consists of two modules: - module 1: to cluster the observed area into convenient collection sectors by means of clustering algorithms; - module 2: to identify optimal retrieval routes within each cluster by using Vehicle Routing models. The province of Cagliari in Sardinia (Italy) has been identified as test area. An extensive data collection process has been performed in order to collect the information necessary to portray the existing scenario. The following businesses have been recorded: grocery stores and supermarkets with at least 400 sqm of retail area, livestock farms with at least 200 heads of cattle, feed mills. A number of variables concerning location, type, size and demand data have been collected for each recorded unit.The management scheme has been implemented in a software platform and successfully applied in the test area. The outcome provides useful insights to stakeholders and suggests avenues for further research in the area in order to develop a more general and intuitive tool for managing reverse logistics processes in agrifood chains
