Sensitivity of changes in supply and prices in passenger traffic (SVI1998/090)
Overview
Background & policy context:
In addition to adequate data, the formulation of transport forecasts relies upon a knowledge of the relationships between the demand for transport and those factors which influence it. These relationships are described with mathematical functions and the their model parameters. The parameters derived from revealed preference (RP) data are often subject to too many imponderables and are thus of only limited value in many cases. The main cause of this uncertainty is data which is either insufficiently detailed or unsuitable for estimating transport demand functions.
Objectives:
The main aim of the project is to estimate the elasticity of demand in Switzerland's passenger traffic using standard statistical methods and new empirical data.
Another goal of the study is to identify advantages and disadvantages of newer methods of estimating the elasticity of demand and to assess these methods with regard to their applicability to Swiss conditions.
The results of the study should represent a basis for analysis of different measures in the field of transport to estimate effects of demand at least roughly.
Methodology:
Applying various appropriate statistical (traditional and newer) methods on new empirical data.
A case study for Switzerland, but foreign studies were taken into account.
