Technological development from horse-drawn carriages to the new Airbus A380 has led to a remarkable increase in both the capacity and speed of tourist travel. This development has an endogenous systemic cause and will continue to increase carbon dioxide emissions/energy consumption if left unchecked. Another stream of technological research and development aims at reducing pollution and will reduce emissions per passenger-kilometer, but suffers from several rebound effects. The final impact on energy consumption depends on the strength of the positive and negative feedback in the technology system of tourism transport. However, as the core tourism industry including tour operators, travel agencies, and, accommodation has a strong link with air transport, it is unlikely that technological development without strong social and political control will result in delivering the emission reductions required for avoiding dangerous climate change.

In dit rapport worden de maatschappelijke kosten en baten onderzocht van waterstof-elektrisch rijden voor vrachtverkeer. De keten van elektriciteitproductie, conversie naar waterstof, opslag en transport van waterstof, waterstoftankstation en waterstofvrachtwagen is gemodelleerd. De total cost of ownerschip en ook de levelised cost of driving van waterstof-elektrisch rijden zijn hoger dan de alternatieven diesel en batterijelektrisch rijden. Ten opzichte van batterijelektrisch rijden kent waterstof wel enkele operationele voordelen zoals de kortere tanktijd en het hogere bereik. Ook niet-monetaire effecten zijn geanalyseerd.

Standard mass-production is a well-known manufacturing concept. To make small quantities or even single items of a product according to user specifications at an affordable price, alternative agile production paradigms should be investigated and developed. The system presented in this paper is based on a grid of cheap reconfigurable production units, called equiplets. A grid of these equiplets is capable to produce a variety of different products in parallel at an affordable price. The underlying agent-based software for this system is responsible for the agile manufacturing. An important aspect of this type of manufacturing is the transport of the products along the available equiplets. This transport of the products from equiplet to equiplet is quite different from standard production. Every product can have its own unique path along the equiplets. In this paper several topologies are discussed and investigated. Also, the planning and scheduling in relation to the transport constraints is subject of this study. Some possibilities of realization are discussed and simulations are used to generate results with the focus on efficiency and usability for different topologies and layouts of the grid and its internal transport system.

Some possibilities of realization are discussed and simulations are used to generate results with the focus on efficiency and usability for different topologies and layouts of the grid and its internal transport system. Closely related with this problem is the scheduling of the production in the grid. A discussion about the maximum achievable load on the production grid and its relation with the transport system is also included.

Purpose: This is a position paper describing the elements of an international framework for assistive techhnology provision that could guide the development of policies, systems and service delivery procedures across the world. It describes general requirements, quality criteria and possible approaches that may help to enhance the accessibility of affordable and high quality assistive technology solutions. Materials and methods: The paper is based on the experience of the authors, an analysis of the existing literature and the inputs from many colleagues in the field of assistive technology provision. It includes the results of discussions of an earlier version of the paper during an international conference on the topic in August 2017. Results and conclusion: The paper ends with the recommendation to develop an international standard for assistive technology provision. Such a standard can have a major impact on the accessibility of AT for people with disabilities. The paper outlines some the key elements to be included in a standard.

Abstract: Last few years the hindrance, accidents, pollution and other negative side effects of construction projects and namely construction transport have become an issue particularly in urban areas across Europe such as in London, and in the Netherlands as well, including the cities of Utrecht, Rotterdam and Amsterdam. Municipalities have issued new legislation and stricter conditions for vehicles to be able to access cities and city centres in particular and accessibility of older and polluting vehicles. Considerate clients, public as well private, have started developing tender policies to encourage contractors to reduce the environmental impact of construction projects. Contractors and third party logistics providers have started applying consolidation centres. These developments have shown considerable reductions of number of vehicles needed to deliver goods and to transport workers to site. In addition these developments have led to increased transport efficiency, labour productivity and cost reductions on site as well as down the supply chain. Besides these developments have led to increased innovations in the field of logistics planning software, use of ICT , and handling hardware and equipment. This paper gives an overview of current developments and applications in the field of construction logistics in the Netherlands, and in a few project cases in particular. Those cases are underway as part of an ongoing applied research project and studied by using an ethnographic participative action research approach. The case findings and project results show initial advantages how the projects, the firms involved and the environment can profit from the advancement of logistics management leading to reduced environmental impact and increased efficiencies of construction transport.

The aim of this research/project is to investigate and analyze the opportunities and challenges of implementing AI technologies in general and in the transport and logistics sectors. Also, the potential impacts of AI at sectoral, regional, and societal scales that can be identified and chan- neled, in the field of transport and logistics sectors, are investigated. Special attention will be given to the importance and significance of AI adoption in the development of sustainable transport and logistics activities using intelligent and autonomous transport and cleaner transport modalities. The emphasis here is therefore on the pursuit of ‘zero emissions’ in transport and logistics at the urban/city and regional levels.Another goal of this study is to examine a new path for follow-up research topics related to the economic and societal impacts of AI technology and the adoption of AI systems at organizational and sectoral levels.This report is based on an exploratory/descriptive analysis and focuses mainly on the examination of existing literature and (empirical) scientific research publica- tions, previous and ongoing AI initiatives and projects (use cases), policy documents, etc., especially in the fields of transport and logistics in the Netherlands. It presents and discusses many aspects of existing challenges and opportunities that face organizations, activities, and individuals when adopting AI technology and systems.

The objective of the ITRACT2 project is to create attractive transport options for regions with low population densities including rural areas. A basic assumption of the ITRACT project is that information and communication technology can be used to build IT services that allow for more adaptive transport services and that these adaptive transport services create a better match between supply (transport schedules) and demand (traveller needs) and therefore a more viable business case.
