characteristics of commuters in for example the Netherlands. Therefore, the probabilities
found are not directly transferable to commuters in general.
Furthermore, it is good to put the observed probabilities specifically due to a road pricing
measure in the light of the probability that the respondents are going to relocate anyway.
Therefore, the questionnaire contained two questions regarding the chance of changing house
or job within a certain period (i.e. 2 years). Table 4 shows the relation between the probability
of moving the residential location specifically due to road pricing and the probability of
moving house within 2 years for whatever reason. There seems to be a clear positive and
significant relation (i.e. Kendall’s tau-b is positive and significant) between a high probability
of moving the residential location due to road pricing and between a high probability of
moving house within 2 years for whatever reason. Furthermore, the same kind of positive
significant relation is found between a high probability of searching for another job due to
road pricing and the probability of changing job within 2 years. Thus, in general the majority
of respondents that reported a high probability of changing location due to a road pricing
measure also seem to consider relocation anyway. On one hand one may conclude therefore
that the actual probability of relocation specifically due to road pricing is lower than presented
in the tables 2 and 3. On the other hand however, road pricing can still be the initiating factor
leading to relocation when people already consider relocation (for whatever reason).
