Have information technologies forgotten pedestrians?
2018
Worldwide, pedestrians make up close to half of all motor-vehicle related fatalities but disproportionally little of the research in Information Technologies (IT) in general and Intelligent Transportation Systems (ITS) in particular has aimed at pedestrian safety improvements. This paper analyses and compiles three different ways so that IT and ITS can be used in order to improve mobility and safety of pedestrians in urban spaces: (a) for contacting and/or being localized, (b) for guidance (leading/navigating), (c) for alerting or informing of a danger. The aim is to categorize recent experiences where ITS can improve pedestrians’ mobility and safety so that new ideas based on ITS will be d…
Using recursive Bayesian estimation for matching GPS measurements to imperfect road network data
2010
Map-matching refers to the process of projecting positioning measurements to a location on a digital road network map. It is an important element of intelligent transportation systems (ITS) focusing on driver assistance applications, on emergency and incident management, arterial and freeway management, and other applications. This paper addresses the problem of map-matching in the applications characterized by imperfect map quality and restricted computational resources - e.g. in the context of community-based ITS applications. Whereas a number of map-matching methods are available, often these methods rely on topological analysis, thereby making them sensitive to the map inaccuracies. In …
Intelligent transport systems harmonisation assessment: use case of some Spanish intelligent transport systems services
2013
From the 1980s, new telematic technologies have meant a great evolution in several areas. In the transportation domain, their use has implied the development and implementation of several intelligent transport systems (ITS). However, these deployments were done in an isolated way. Traffic managers, public and private organisations, stakeholders and others have implemented ITS without much perspective, that is, without providing ITS as services for end users. In the last few years, several European Union (EU) funded projects have been dealing with the development of harmonised ITS services. For example, the EasyWay Project is involving most of the European countries (EU member states and oth…
Long-Term Exposure to Transportation Noise and Risk for Type 2 Diabetes in a Nationwide Cohort Study from Denmark
2021
Background: Epidemiologic studies have linked transportation noise to increased morbidity and mortality, particularly for cardiovascular outcomes. However, studies investigating metabolic outcomes such as diabetes are limited and have focused only on noise exposures estimated for the loudest residential façade. Objectives: We aimed to examine the influence of long-term residential exposure to transportation noise at the loudest and quietest residential façades and the risk for type 2 diabetes. Methods: Road traffic and railway noise exposures (Lden) at the most and least exposed façades were estimated for all dwellings in Denmark during 1990–2017. Aircraft noise was estimated in 5-dB catego…
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…
Cooperation Formats of China and Europe: Synergies and Divergences
2017
Abstract This contribution articulates the synergies and divergences of the various formats of cooperation between China and the European countries. The EU and China have a strong interest in each other’s flagship initiatives, namely the Investment Plan for Europe, and the One Belt, One Road Initiative (Silk Road Economic Belt and 21st-Century Maritime Silk Road). The authors argue that there are certain synergies between these initiatives. Furthermore, the new initiative EU-China Connectivity Platform is aimed to explore these synergies. The authors explore the recent developments in the EU-China investments, trade cooperation and the challenges of the ever-growing CEEC-China partnership i…
Les études hédoniques soutiennent-elles une valeur verte élevée dans le bâtiment ? Une réponse par la méta-analyse
2018
International audience; La place majeure occupée par le secteur du bâtiment dans la consommation d'énergie (40%) et les émissions de gaz à effet de serre (1/3 des émissions) explique le développement du débat scientifique axé sur la réduction de l'impact environnemental du bâtit et sur ses leviers. Ces dernières années ont notamment vu croitre une littérature considérable relative à la disposition à payer du public pour les bâtiments « verts » labélisés par des écolabels, cette « valeur verte » étant estimée dans la grande majorité des études via des modèles hédoniques. Dans cet article, nous proposons d'offrir une synthèse de ces résultats dans le cadre d'une méta-analyse portant sur plus …
Microstructure and rheological response of laboratory-aged SBS-modified bitumens
2019
Polymer additives are widely used to improve the performance of road bitumens including their resistance to hardening during oxidation, although their oxidative inhibitor effect has not been well documented. This study aims to investigate the effect of laboratory-simulated ageing on the microstructure, and rheological properties of Polymer Modified Bitumens (PMBs) prepared with a Styrene-Butadiene-Styrene (SBS) copolymer and sulphur as a cross-linker. The laboratory ageing was conducted through the Rolling Thin Film Oven (RTFO) and the Pressure Aging Vessel (PAV) procedures. The unaged and aged binders were characterised using the Multiple Stress Creep and Recovery (MSCR) test, Gel Permeati…
Resorcinarene Crowns ☆
2017
Resorcinarene crowns are a class of supramolecular hosts combining a crown ether moiety to a resorcinarene platform as either a podand arm, lower rim substituent, or a bridge. Resorcinarene crowns act as cation hosts and have therefore shown potential in ion transportation and in antibacterial applications.
