Investigation of route choice behaviour in passenger transport

The continually increasing population, the rising economic activity and the permanent race for the rise of economic prosperity, led us to the increase of motorisation. Transportation sector has an important role, because it is not only using the lacking fossil energy sources and polluting the environment, but because of our social and economic structure it is the sector that can hardly change because of the big social resistance. One of the substantial preconditions for the change into an environmental friendly, sustainable system is correct data provision to the regulator (quality and quantity as well). One way for reduction of transport related environmental pollution is to give right price signal to the users with internalisation of transport related external costs. In our article we tried to examine the route choice behaviour in Hungary focusing on toll roads. Our aim in this paper is to analyze the correlation of control possibilities of such econometric phenomena with mathematic tools.
