Validation and sensitivity analysis for national freight model of the Federal Department of the Environment, Transport, Energy and Communications (09013)
Overview
Background & policy context:
The PTV AG in collaboration with ASTRA and the BAV worked out a bimodal traffic model for the national freight transport DETEC (NGVM-DETEC). The model structures with the application to perform the calculations were worked out and for the state in 2005 a first non-calibrated matrix with traffic loads was worked out.
Objectives:
Due to the complexity of the model a variety of input data is required, which is sometimes only possible by gain by plausible assumptions. In order to improve the model quality and to get a better overview of the model reactions and applications, a national freight transport model shall take into account the aggregated and disaggregated modular point of view and thereby complements the existing NGVM.
Methodology:
Above mentioned objectives will be achieved by following steps:
- Validation of input and output data and calibration of the model for the status quo in 2005, to improve the model quality.
- Verification of the model structures with the sensitivity analyzes in order to understand the reactions of the model at varying individual factors.
