• TITLE: Calibration and Validation of Strategic Freight Transportation Planning Models with Limited Information

  AUTHORS: Bart Jourquin

  KEYWORDS: Calibration, Validation, Network, Freight Transport, Modal Choice, Assignment

  JOURNAL NAME: Journal of Transportation Technologies, Vol.6 No.5, September 26, 2016

  ABSTRACT: Strategic transportation network models are often used as support tools in the framework of decisions to be taken at the policy level, such as the Trans-European Network projects. These models are mostly setup using aggregated or limited data. If their calibration is regularly mentioned in the literature, their validation is barely discussed. In this paper, several modal choice model specifications that make only use of explanatory variables available at the network level are described and applied to a large scale case. A validation exercise is performed at three levels of aggregation. The paper is designed from a strategic transport planning perspective, and does not present new modal choice formulations or assignment procedures. Its main added value is the focus on calibration and validation considerations. Despite the limited explanatory information used, the global performance of the best models can be considered as satisfactory. However, the quality of the models varies from mode to mode, the use of railway transport being the most difficult to predict without more specific input.
