City logistics – how to create an OD matrix for goods transports within the city of Oslo?

In this paper we will examine the advantages of using existing trade statistics to construct an OD matrix for freight transport for a city area. The OD matrix is constructed by examining how a wholesaler relate to the retailer industries. If this work is successful it will improve the quality of data quite substantially for city models. The result from use of such information may give more accurate results and have the potential for improving the planning of a city area. The outline of this paper will first be a stepwise recipe for constructing the OD –matrix and finally discuss some of the assumptions we have done in order to arrive to the result of construction of a matrix. We will finally discuss how robust is this method compared to survey data.

本文将探讨利用现有贸易统计数据构建城市区域货运起讫点（Origin-Destination, OD）矩阵的优势。该OD矩阵通过分析批发商与零售行业之间的关联关系进行构建。若本研究取得成功，将大幅提升城市模型所用数据的质量。运用此类信息所得的分析结果可提升预测精度，且有望助力优化城市区域的规划工作。本文结构安排如下：首先给出构建OD矩阵的分步操作指南，随后阐述为完成矩阵构建工作所采用的各项假设前提。最后，本文将对比调研数据，探讨该方法的稳健性表现。
