Freight distribution in urban areas:a method to select the most important loading and unloading areas and a survey tool to investigate related demand patterns
No full textCities all around the world are observing increasing levels of urban freight activities owing to the growth of internet shopping combined to the traditional distribution to shops, creating additional problems in terms of congestions and environmental impacts. This study, developed within the European Project SUITS framework, aims at showing how Local Authorities can effectively observe freight flows from the demand side. This led to the design, implementation and testing of a spatial cluster analysis approach to understand which are the most important loading/unloading parking spots in an urban setting by processing the GPS traces of a fleet of logistic vehicles. Later field activities should focus on these important areas to maximize the efficiency of the survey. A survey of retailers and shops in such areas to observe delivering activities is then proposed. The whole process, namely the spatial analysis and the field survey, was then tested to the real case of an Italian city (Turin) to assess the potentiality of the methods. The methodology proposed can give useful insights to Local Authorities on a way of monitoring the freight distribution patterns at the more disaggregated individual loading/unloading area.</p

Freight delivery services in urban areas: Monitoring accessibility from vehicle traces and road network modelling
No full textLocal Authorities plays a fundamental role in the management of city mobility and in accounting for the needs of different stakeholders involved in the urban freight transport. The aim of this study is to develop a method that could support the evaluation of the city accessibility for freight distribution services. As Local Authorities can use floating vehicle data (FVD), which are a current trend in mobility management, gaining new knowledge from data could be crucial to help the various stakeholders to better address their needs. Accessibility in urban areas is investigated through travel time estimations along the most frequently used routes connecting relevant nodes of the city and their average speed using a simplified road network model. After the description of the principal elements of the method, a test case is also presented for the urban area of Turin, Italy, to demonstrate the applicability of the procedures on a real scenario and dataset. The results confirm, also through the use of skim matrices, the value of FVD in assessing the accessibility of different zones interested in delivery operations, which may change over time, providing monitoring functions to urban logistics operators and Local Authorities in managing urban freight flows
Information provision in public transport: Indicators and benchmarking across Europe
No full textThe measurement of the quality of transport services has been the object of an intensive research activity in the last decades. The EU project METPEX aims at advancing the state of the art in this crucial research area through a targeted survey proposed in eight European cities. The dataset is then analyzed to identify latent constructs that can measure the quality of the traveler experience. Several different indicators are proposed to represent detailed aspects related to the perceived quality of transport services. In this paper, we concentrate on those indicators capturing the quality of information provision services in different travel stages: before starting the journey, when passing through stations or stops and while travelling. The results show the added value of separately considering the quality of information provision at different stages of the journey experience, for which different entities could be responsible (e.g. infrastructure managers versus service operators)
Implementing a Solvency II internal model: Bayesian stochastic reserving and parameter estimation
No full textRisk Factor Contributions and Capital Allocation in Life Insurance in the Solvency II Framework
No full textThis book explores the profound transformation that has taken place in European insurance legislation since January 2016. Expert contributions discuss the changes that have taken place in the supervision of insurance and reinsurance undertakings through an economic risk-based approach. They outline the European insurance market before going on to show how Solvency II and Insurance Distribution Directive (IDD) are expected to generate significant benefits and have a positive impact on all parties involved in the insurance industry, the supervisory authorities and the insured. They also show how Solvency II is likely to benefit the economy as a whole, promoting more efficient allocation of capital and risk in a financial stability framework. This volume will be of interest to academics and researchers in the field of insurance regulation
Active mobility perception from an intersectional perspective: insights from two European cities
No full textThe investigation of active mobility perception for different classes of users is crucial to include all mobility needs and increase the accessibility of these modes. Elements like the perception of safety, security and the shape of the urban environment (e.g., provision of cycle paths) are to be considered while analyzing the different mobility choices between men and women. The current study focuses on the answers of a survey among representative samples of the population of two European cities, namely Valencia and Turin. Data collected in these similarly structured ‘bike friendly’ sites are compared following an intersectional approach based on gender and age. The results showed, for example, that, in general, cyclists are somewhat affected by safety issues, especially in terms of sharing space with motor vehicles. Or that women are less satisfied with the level of safety during walking. When considering bike-sharing, women seem more responsive to adding a dedicated space for children to start using this mode. The analysis of the results helps in providing interesting indications and suggestions for transport planning
Gender perceptions of active mobility: Insights from three European cities
No full textEuropean cities have seen an increase in the use of personal means as an effect of the COVID-19
pandemic: they are asked to accelerate the shift towards more sustainable modes, as the active ones. The
current paper tries to shed light on how the perception towards these latter modes changes according to
gender. In the framework of H2020 TInnGO project, data collected through a survey in three European
cities (Turin, Valencia, Paris) are investigated. Results show that women are more worried about safety,
both while walking or riding a bike, as female cyclists do not appreciate sharing space with motor vehicles.
Moreover, the absence of a dedicated space for children prevents women from starting to use bike-sharing.
Comparing the results in the three cities provides interesting indications and suggestions for including the
need of all active modes users in transport plannin
Gender, Smart Mobility and COVID-19
No full textThe COVID-19 pandemic has strongly impacted people’s main routine, which certainly includes their mobility habits. This paper aims to assess the pandemic’s mobility impacts and whether these may have increased the already existing inequality between men and women. In particular, the variation of mode choice in a pre-COVID and post-COVID scenario is investigated, focusing on the use of transport mode defined as Smart Mobility. The analysis is performed on data collected in thirteen European countries between July and September 2020 through a survey designed using an intersectional approach. Responses are analyzed to highlight correlations between different factors affecting mobility changes: some interest is reserved to the modes used according to the journey scope (work, errand, shopping). Overall, results reveal more people walking for their daily journeys, while a significant decrease in the use of public transport is observed. Although these changes affect women more, the main reason behind this is the need for more safety in terms of low risk of contagion, irrespective of gender. A specific focus on using modes commonly associated with a Smart Mobility offer (such as shared modes, public transport, walking, and biking) reveals differences originating when comparing men and women responses and various age ranges
To play but not for travel
No full textActive mobility is the most convenient, healthy, environmental friendliness, suitable for short distance mode of transport. The individual and common benefits linked to the active mobility are recognized all over the world and they justify the growing interest in promoting the bike use. In order to suitably promote cycling, it is important to identify the factors that lead to choose the bicycle. This paper, through a factor analysis and a Hybrid Choice Model, analyzes the way in which the bike is perceived by “utilitarian bikers”, “hedonic bikers” and “non-cyclists”. The data used are drawn from a survey conducted by University of Cagliari (Italy) among a sample of 2752 individuals. The findings confirm a significant influence of socio-demographic variables on the propensity to be hedonic, utilitarian or non cyclists and that latent attitudinal variables can discriminate between utilitarian and non cyclists but cannot discriminate between hedonic and non cyclists
