Abstract

In traffic and transport planning many sorts of models are used on several administrative levels, e.g. traffic models for calculation of traffic volumes and environmental impact analyses for calculating noise and emissions. Modelling of urban freight traffic hardly takes place.

There is a need for desaggregated modelling of freight transport on the urban or regional level to evaluate the effectiveness of certain measures or scenarios to solve the problems concerning urban freight transport, like environmental impacts of freight traffic and accessibility effects of traffic measures, new infrastructure, changes in logistic concepts of spatial planning policies. There is a need for quantitative insight in the impact of new policies or trends.

For this reason a project is started in 1994 at the Delft University of Technology (the Netherlands) to find solutions for the problems concerning urban freight transport. The objectives of the research are (1) to develop an instrument which describes urban goods transport to evaluate measures on their effectiveness in urban areas, (2) to survey and analyse possible solutions and (3) to analyse and evaluate the effectiveness of these solutions. In this research we want to evaluate different strategies and scenarios of facilitating urban freight transport.

For the evaluating of policy measures on accessibility and environmental amenity a decision support system has been developed with a freight transport model. The model can be characterised as a simulation model, with the use of a geographic information system (GIS).

Most of the problems where transport models are used for, have a spatial dimension, like accessibility of locations or traffic noise. Geographic information systems are becoming more and more important in planning environments. These are the reasons why GIS is tested as modelling tool in this project.

In this study we only focus on urban freight transport. The term urban freight transport covers the transport of goods to, in and out of urban areas, conceming the delivery of mostly consumer goods at shops, department stores, supermarkets, hotel and catering industry. Freight transport in urban areas is characterised by the nature of the goods, like consumer goods, post and parcels, express delivery, building materials for building sites and waste, means of transport, mostly road transport, relatively small shipments, and a large number of stops. Building materials and waste are rather bulky and although they have a large share in the transport volumes in urban areas they are not considered in this study.
