Demand and supply of public transport: The problem of cause and effect
2005 (English)In: Thredbo 8, Rio De Janeiro, September 2003, Elsevier , 2005Conference paper (Refereed)
When modelling public transport demand vehicle-kilometres is often included among the explanatory variables and the possibility of a twoway relationship between the variables is often ignored. The purpose of this article is to examine the causal relationship between public transport demand and the supply of vehicle-kilometres. A granger causality test is applied to panel data from Swedish counties ranging from 1986 to 2001 and it is found that while vehicle-kilometres do cause patronage, patronage also cause vehicle-kilometres. Hence, there is a two way relationship between the variables that should be considered when estimating demand models.
