Exploiting 3D Modelling and Life Cycle Assessment to Improve the Sustainability of Pavement Management
2020
Today road agencies worldwide face difficult decisions for construction, maintenance and rehabilitation of their road infrastructure as they try to balance limited budgets. This is further complicated rising environmental concerns over equipment and techniques used for these practices. This has led agencies to consider alternative approaches for smarter and sustainable pavement asset management systems. This paper considers the use of a low-cost 3D image modelling distress identification and classification proposal for data acquisition and analysis. To establish its environmental friendliness, a case study in Palermo, Italy, is considered wherein a Life Cycle Assessment (LCA) exercise is do…
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…
Safety Related Behaviors and Law Adherence of Shared E-Scooter Riders in Germany
2021
Shared e-scooters, whose supply and coverage keeps increasing in many cities around the globe, are rapidly changing mobility in urban road environments. As rising injury rates have been observed alongside this new form of mobility, researchers are investigating potential factors that relate to safe/unsafe e-scooter use. In Germany, e-scooter sharing platforms were only recently permitted in the middle of 2019, and their number has increased steadily since then. The aim of this study was to assess key factors that relate to their safe use, through a direct observation of e-scooters conducted at three observation sites around Berlin. Helmet use, dual use, type of infrastructure use, and trave…
Lethal Traumatic Injuries due to Traffic Accidents
2019
The Global status report on road safety published by the World Health Organization (WHO) in 2015 estimating information from 180 countries indicates that worldwide the total number of road traffic deaths has plateaued at 1.25 million per year. This report, the third Global status report on road safety, shows that low- and middle-income countries are more affected with a mortality rate of 90% of global road traffic deaths.
The Role of Parasocial Interaction and Teleparticipation on Teleshopping Behaviour
2011
Nowadays, television media has evolved into an important channel of direct selling that brands and advertisers are exploiting. Many technological changes (e.g., digital television appearance or the integration of Internet in the TV medium and mobile technology) have increasingly led to consumers see television as a channel for purchasing products and services and as a source of information (Beyer et al., 2007). However, researchers have put little interest on teleshopping, one of the consumer behaviour phenomena.
Public versus private broadcasters’ management
2014
Purpose – The purpose of this paper is to prove the existence of significant differences between private and public corporate credibility antecedents and effects. Design/methodology/approach – Totally, 816 Spanish viewers’ valuations were obtained (408 for the public television network and 408 for four private first generation broadcasters). Results show that some corporate reputation antecedents (perceived quality) and effects (attitudes) are stronger when private broadcasters are considered. Findings – Result show that proposed credibility reputation antecedents and effects are significant and that some differences between private and public entities really do exist. Research limitations…
Food waste reduction and taking away leftovers: Interplay of food-ordering routine, planning routine, and motives
2021
The hospitality literature is quite deficient in insights on consumer behaviour towards food waste generation and its mitigation in out-of-home dining. The present study addresses this gap by undertaking a mixed-method study to examining a broad spectrum of diners’ behaviour, beginning from planning the meal and ending with bringing the leftovers home. To this end, it utilises the Stimulus-Organism-Response theory to conceptualise the association of planning routine, food-ordering routine, motives, attitude, and behaviour of taking away leftovers and throwing away leftovers. The results of analysis of the data collected from 276 diners in the United States confirm a positive association of …
No public value without a valued public
2017
This study aims to enlighten the controversial discussion about the term public value in an innovative way. Instead of normative pronouncements and paternalistic posits, this study combines a theoretical, literature-based conception with an empirical quantitative approach. For this, the key term, public value, is split into its constituent parts of customer value and citizen value and is transformed into measurable attributes. By means of a choice-based conjoint analysis on panel data for Germany and the United Kingdom, we explore which performance attributes of public service broadcasters are the most important. Based on the results, we create a conception of public value from the perspect…
Channel Modeling and System Concepts for Future Terahertz Communications: Getting Ready for Advances Beyond 5G
2020
Future terahertz (THz) communications will utilize the frequency spectrum around 300 GHz. This technology provides a promising solution for future high-data-rate communications due to the high available bandwidth. However, the unfavorable channel characteristics are a major barrier for the realization of THz communications. To address the challenges caused by the unfavorable propagation conditions, the world?s first THz communication standard includes a channel-modeling document (CMD).
Morphological similarities between DBM and an economic geography model of city growth
2009
International audience; An urban microeconomic model of households evolving in a 2Dcellular automata allows to simulate the growth of a metropolitan area whereland is devoted to housing, road network and agricultural/green areas. Thissystem is self-organised: based on individualistic decisions of economic agentswho compete on the land market, the model generates a metropolitan area withhouses, roads, and agriculture. Several simulation are performed. The resultsshow strong similarities with physical Dieletric breackdown models (DBM). Inparticular, phase transitions in the urban morphology occur when a controlparameter reaches critical values. Population density in our model and theelectric …
