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…

Game Theory with Engineering Applications

2016

Engineering systems are highly distributed collective systems—decisions, information, and objectives are distributed throughout—that have humans in the loop, and thus decisions may be influenced by socioeconomic factors. Engineering systems emphasize the potential of control and games beyond traditional applications. Game theory can be used to design incentives to obtain socially desirable behaviors on the part of the players, for example, a change in the consumption patterns on the part of the “prosumers” (producers-consumers) or better redistribution of traffic. This unique book addresses the foundations of game theory, with an emphasis on the physical intuition behind the concepts, an an…

Building composite indicators in tourism studies: Measurements and applications in tourism destination competitiveness

2017

Abstract Composite indicators are useful tools to synthesize and monitor multidimensional phenomena. The aim of this paper is twofold: to offer the methodological foundations to build composite indicators in tourism and to evaluate a set of currently available composite indicators. Tourism destination competitiveness indicators constitute the object of this contribution. Their definitions, concepts and measures are analyzed and their evaluation is performed through the application of an original protocol. The results highlight that several methodological issues still surround the measurement of destinations competitiveness indicators. This paper provides tourism scholars and practitioners w…

Building transformative capacity towards active sustainable transport in urban areas – Experiences from local actions in Finland

2022

Recent research has recognised cycling and walking (active transport) as substantial elements contributing to sustainable mobility and public health challenges. There is less knowledge available on the integrated contributions of local-level governance processes and practical implementation of active transport promotion activities. To illustrate comprehensively the contributions of local-level activities, we defined a framework presenting transformative capacity towards active sustainable transport. The framework presents the essential elements and criteria in assessing the level of contributions towards active and sustainable mobility. Previous literature and a case study in six Finnish mu…

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…

Hybridizing large neighborhood search and exact methods for generalized vehicle routing problems with time windows

2021

International audience; Delivery options are at the heart of the generalized vehicle routing problem with time windows (GVRPTW) allowing that customer requests are shipped to alternative delivery locations which can also have different time windows. Recently, the vehicle routing problem with delivery options was introduced into the scientific literature. It extends the GVRPTW by capacities of shared locations and by specifying service-level constraints defined by the customers' preferences for delivery options. The vehicle routing problem with delivery options also generalizes the vehicle routing problem with home roaming delivery locations and the vehicle routing problem with multiple time…

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…
