Exploiting Data Analytics and Deep Learning Systems to Support Pavement Maintenance Decisions

2021

Road networks are critical infrastructures within any region and it is imperative to maintain their conditions for safe and effective movement of goods and services. Road Management, therefore, plays a key role to ensure consistent efficient operation. However, significant resources are required to perform necessary maintenance activities to achieve and maintain high levels of service. Pavement maintenance can typically be very expensive and decisions are needed concerning planning and prioritizing interventions. Data are key towards enabling adequate maintenance planning but in many instances, there is limited available information especially in small or under-resourced urban road authorit…

Materiality assessment in sustainability reporting : case study of the airline industry

2017

Materiality has been heavily emphasized in different sustainability reporting guidelines to increase the quality of the sustainability reports and report issues that are most aligned with the company’s most significant economic, environmental and social issues. In this thesis materiality analysis in sustainability reporting is analyzed. Firstly, in the theoretical part, the concept of sustainability reporting and materiality is explained along with the provision of materiality in different reporting guidelines. In this research section, fifteen different airlines’ sustainability reports are analyzed to find out how the materiality analysis is carried out in the airlines. The study is focuse…

DEVELOPING A 3D ROAD CADASTRAL SYSTEM: COMPARING LEGAL REQUIREMENTS AND USER NEEDS

2018

Abstract. Road transport has always played an important role in a country’s growth and, in order to manage road networks and ensure a high standard of road performance (e.g. durability, efficiency and safety), both public and private road inventories have been implemented using databases and Geographical Information Systems. They enable registering and managing significant amounts of different road information, but to date do not focus on 3D road information, data integration and interoperability. In an increasingly complex 3D urban environment, and in the age of smart cities, however, applications including intelligent transport systems, mobility and traffic management, road maintenance an…

Carsharing business models in Germany: characteristics, success and future prospects

2017

Carsharing provides an alternative to private car ownership by allowing car use temporarily on an on-demand basis. Operators provide carsharing services using different business models and ownership structures. We distinguish between cooperative, business-to-consumer (B2C) roundtrip and one-way, as well as peer-topeer (P2P) carsharing. This paper characterizes these different types of business models and compares their success in terms of diffusion using a comprehensive database of all 101 German carsharing providers in 2016. The key result holds that fleet size is significantly different across business models ranging from a few cars (cooperatives in small towns), to a few hundred (B2C rou…

Climate change influences on aviation: A literature review

2020

While the aviation sector has long been referenced as contributing to the causes of climate change, the need for aviation to adapt to the consequences of climate change has not been as well researched or considered. The paper is a systematic quantitative literature review on climate change and aviation, which aims to explicate significant issues affecting aviation in a changing climate and to identify the aviation industry responses on climate change and adaptation. There are 46 references involved in the detailed assessment, selected according to variables such as methodology, paper outcomes and industry stakeholder. This emergent aviation and climate change adaptation literature could be …

The renaissance of tramways and urban redevelopment in France

2017

Abstract Tramways have made a remarkable comeback in France since the 1980s. An organization of public transport based on the decentralized administration system set up in the early 1980s has allowed local urban authorities to make their own choices to develop public transport networks in the context of automobile domination. As in many other countries, worries about fossil fuel dependency and demands concerning sustainable urban development appear as strong elements in favour of urban light rail. However, in France, tramways are not just technical solutions for traffic congestion, they have also become a symbol of a cultural mutation in urban development planning. Coupled with a national p…

Does Car Sharing Contribute to Urban Sustainability from User-Motivation Perspectives?

2021

Mobility, its current state and development perspectives in the future creates challenges with respect to sustainability, the first of which is the uncontrolled increase in greenhouse gas emissions in the last few decades, while road transport is one of the “sinners” creating long-term negative impact. The second is the dominance of car travel and car usage in the passenger transportation segment before the latest COVID-19 pandemic accelerated environmental problems. Although recent trends show new, greener patterns in consumption, there is still a relatively low share of consumers acknowledging the importance of sustainable and green preferences. This research study aims to investigate car…

Persistent traffic offenders. Alcohol consumption and personality as predictors of driving disqualification

2019

espanolLa seguridad vial es un importante problema social. Muchos accidentes se deben al incumplimiento de las normas de trafico. Las infracciones graves o reiteradas se sancionan por la via administrativa o judicial y en ambos casos las sanciones pueden suponer la perdida del permiso de conducir. Este articulo explora la relevancia del alcohol y la personalidad como factores predictivos. El objetivo del estudio es determinar si el comportamiento delictivo de los infractores persistentes esta relacionado con sus caracteristicas de personalidad y patrones de consumo de alcohol. Se utilizo una muestra de 358 conductores: 232 infractores persistentes, a los que les habia sido retirado el carne…
