high or extremely high probability of moving to another residential location when a road
pricing measure would be implemented. The probability of searching for another job on the
other hand was found to be significantly higher for all price measures. On average 13.5
percent of the respondents responded that the probability of searching for another job would
be quite high, high or extremely high. However, these results must be put into perspective.
The majority of respondents that indicated that the probability of moving house or changing
job due to a road pricing measure is quite high, high or extremely high, also answered that the
chance of changing house or work within 2 years (for whatever reason) is considerable.
Therefore, the actual relocation specifically due to road pricing may be lower than the
observed percentages.
Several significant explanatory variables were found for the probability of changing the
residential location or searching for another job specifically due to a road pricing measure.
Respondents getting a travel cost compensation by their employers, respondents living in a
bigger city and those who live in a region with higher congestion problems seem to have a
lower probability of relocating due to a price measure. Respondents working more hours per
week on the other hand have a higher chance of moving. In the case of changing job, the
commuting distance is an important explanatory factor. Respondents with a higher
commuting distance seem to have a higher probability of changing job due to a road pricing
measure. Finally, perceptions and behavioural characteristics seem to form important
explanatory variables. Respondents, which have the feeling that they are better of or those that
regard the road pricing measure to be acceptable, indicate a lower probability of relocating.
Furthermore a positive relation is found between short term trip behaviour changes and longer
term location changes on one hand and between residential and work location change on the
other hand. This means that for respondents that indicated to change their trip behaviour due
to a road pricing measure also a higher relocation probability was found. And that people
having a higher probability of changing their work location also have a higher probability of
changing the residential location and vice versa.
Looking at the influence of different variables in the actual residential location choice of car
commuters confronted with traffic congestion on a regular basis (i.e. the sample), travel cost
seems to be an important factor. First of all respondents are more sensitive to travel costs than
to housing costs. In the second place respondents value travel time less negatively than travel
costs. Overall this may lead to the conclusion that respondents in general prefer to pay
