Demand and Supply of Public Transport--the Problem of Cause and Effect

The objective of this chapter is to determine the nature of the causal effect between public transport patronage and vehicle-kilometers. In order to achieve this concept, the concept of Granger—causality is used. Granger—causality is a definition of a cause and effect relationship between variables that utilizes the time-lag between the cause and the effect. The concept will further be discussed in the chapter, and to the author’s knowledge no similar studies of cause and effect in public transport have been made. First the development of patronage and vehicle-kilometers in Sweden is described. Next, the rationale for using vehicle-kilometers in travel-demand models will be explained. Then the concept of causality and the tests of cause and effect will be discussed and the last part of the chapter discusses estimation and interpretation of the results using the data from Sweden.
