One of the important policy strategies in order to meet the elements of a sustainable society is the modal shift of road transport to more environmentally-friendly modes like railroad, coastal and barge transport. To compete with road transport, these transport modes are multi-modal set-up as intermodal transportation services with pick-up and delivery serviced by trucks. The general logistical concept for intermodal transportation handling is as follows: a carrier picks up an empty container from an empty dept by truck, leads the container at the shipper's location and brings the container to the nearest terminal. The terminal operator receives this container, stacks the container temporarily and transships the container on the scheduled train or barge service. For fixed departure-times, a train or barge with fixed capacity departs for a long distance trip to another terminal. The container is temporarily stacked and a carrier arranges the final delivery to the customer. Other transport modes, like air and pipelines, can also be part of an intermodal transport system but these modes normally apply to different kinds of load units. This paper focuses on intermodal transportation services that have survived competition in business practice or have good potential to be accepted as serious alternative intermodal transport services.

Het aantal succesvolle SDC's is in de praktijk nog steeds zeer schaars. Er is weinig gepubliceerd over de praktische zaken en ervaringen van het daadwerkelijk runnen van een SDC en het aanbieden van SDC-diensten. In Nederland heeft Binnenstadservice (BSS) al meer dan tien jaar ervaring met SDC's en SDC-services. In deze bijdrage bespreken we de ontwikkeling van een SDC en de praktische ervaringen in de vorm van zeven lessen, waaronder de ontwikkeling van het bedrijfsmodel, het organisatiemodel, en de ontwikkeling van het aanbieden van ‘alleen’ de cross-dock van fysieke stromen naar een volledige geintegreerd cross-dock systeem voor de handeling van de fysieke, financiele en informatiestromen. In de toekomst kunnen SDC's ‘het antwoord’ zijn op stadslogistiek zonder uitstoot.

To realise successful implementation of delivery robots in public spaces, it is important to study the interaction between robots and the traffic environment. The traffic environment includes the physical infrastructure and the objects using it like cars and people.Methods: This research proposes an assessment method to determine the readiness of a traffic environment for autonomous delivery robots. A conceptual model is proposed that includes the factors that determine this so-called “roboreadiness”. The two key components of the model are the performance of the robot in the traffic environment and its social acceptance. A real-life experimental test case, expert interviews, and a survey are used to refine and validate the framework.Results: The real-life test case showed for the basic variant a sufficient level both on performance and social acceptance. All other variants such as pillars, ...

Sustainable urban goods transport should facilitate a continuing economic growth and meanwhile protecting the environment and ensuring a better quality of life for future generations. In Netherlands various regulations have been implemented with the aim to maintain the urban living environment with sustainable qualities and to facilitate smooth and safe traffic flows. Most of these regulations have been widely implemented. However, the diversity of these regulations among municipalities can cause serious (planning) difficulties for logistics operators. A detailed evaluation of the measures gives us insight into how policy measures should be implemented in order to reach sustainable urban goods transport Therefore it is possible to get some idea what the impact of the OECD white paper is on municipalities in European countries.

Finding out how actors perceive a situation, or-to be more realistic-reflecting on the consequences if actor perceptions were such-andso, may well be the primary task of a policy analyst. In this paper, we present a conceptual modeling approach to actor network analysis, and a computerized support tool we are in the process of developing. The modeling language is based on the policy network paradigm and embodies concepts from cognitive mapping and linguistic approaches to approximate reasoning. The present tool design includes support for 'gut feeling analysis', graphical rendering of perceptions, and a range of analytic queries.

Lately, due to new waste management legislation, the emphasis has been shifting to recovery, due to the high costs and environmental burdens of disposal. Recently, at regional level, municipalities have become more aware of the fact that waste collection is one of the key elements in the reverse logistics chain. For a specific new area to be built in a Dutch town, called Ahnere, we have carried out a feasibility study on underground waste collection. The parties in question have put up a list of criteria which has been set up to evaluate this new system. By applying a multicriteria analysis, the underground collection system has been compared with the traditional way of collecting. Of course, the criterion costs belong to the most important evaluation criteria. Although the construction costs are extremely high, the exploitation costs of such a system show an improved performance. Based on the performances on the multi-criteri...

In Holland many underground projects spring up like mushrooms, starting a definition phase to test the feasibility of the first underground designs. In order to gain a structured insight into the logistic dependencies, this paper defines three modelling levels of control: at vehicle level (micro), in order to control the traffic movements of the vehicles at handling areas and tubes; at transport order level (meso), in order to control the transport orders, the assignment of shipments and vehicles, and the empty vehicle stock management; and at interconnection level (macro), in order to achieve good connectivity with the schedules of the external transportation modalities.

Due to these societal impacts there is a need for a more explicit intervention by governmental policies. This development demonstrates that the growing importance of transition and innovation in logistic concepts is shifting away from the traditional boundaries of these concepts. Logistics concepts nowadays have to serve multiple values (social, economic, environmental) related to the multiple interests of an increasing number of stakeholders. This introduces a challenge for the methodologies/analytical approaches, used to support multiple actor decision-making on new logistics concepts. This study is triggered by the observation that analytical approaches for design and evaluation do not sufficiently match the requirements of societal involvement in logistics. Our research has provided evidence that the involvement of public actors in logistics con...

For this reason it is interesting to compare and evaluate the differences of policy measures within municipalities. In this paper an inventory of policy measures have been carried out among ...

Most of the transport demand is absorbed by road transport causing congestion problems and negative environmental impacts. Improving the living quality of the city seems to be an important goal for the local governments of both countries. Various policy measures are taken by the local authorities to satisfy some of these goals. Confronted with the differences in policy measures the research orientations have also a different scope. The ways of modelling and implementing are, at a glance, completely different, but integration of both leads to new promising ideas. These ideas can be interpreted as a first step towards a more general approach for changing attitudes in the field of city logistics.

The attention of governments especially for urban goods movement has increased over recent years and with that the number of studies in the urban goods movement field. However, the practice of city logistics policies is not very often the result of detailed analyses and evaluations. This is reflected in similar types of regulations repeated through the different cities regardless of their characteristics, the same schedules for time windows and load zones, and the failure to recognise different types of urban distribution which require different types of regulations. Apart from copying regulation frameworks, however, cities hardly share information, knowledge or cooperation. The lack of national or regional bodies dealing with city logistics, as there exist for urban passenger traffic, is significant. In this paper we will address the main research contributions in city logistics and try to illustrate how the research contributions are (not) related to the daily practice of policymaking and town planning. Finally we will end with the conclusion that a real gap exists between research and practice and provide some explanations, conditions and directions for setting up new research projects.

The objective of this study is to model port choice and obtain insight into port choice decisions for European container imports from Asia. The importance of port choice factors and their impact on port market shares in the hinterland were investigated. Furthermore, sensitivity of the model in predicting the impact of increasing fuel prices on port hinterlands was tested. Containerised imports of 231 European mainland regions were compiled, based on shipping data, port statistics, modal split and gross regional products. Using literature sources, 11 port choice factors were selected; five of these were found to be statistically significant. These factors and their respective weights were used as input for a logit port choice model to analyse container port imports for 31 ports; the most detailed model yet. A varying oil price scenario was used to show the application and sensitivity of the model. Changing oil prices were found to have an impact on modal split and on the average hinterland transport distance.
