The average percentage of respondents (seen over all measures) that indicated the probability
of moving house to be quite high, high or extremely high, amounts to 5.1 percent (i.e. the
average value of the numbers in the row ‘Sum 5 to 7’). Looking only at a high or extremely
high probability, this value decreases to 3.0 percent (average value over price measures for
row ‘Sum 6 to 7’). The cordon charge (i.e. M4 and M5) shows the highest probability of
moving. This seems in line with the expectation that a more spatially differentiated charge (in
this case the cordon charge) leads to higher relocation probabilities (see also section 2).
However, only respondents that were expected to cross a cordon during their commuting trip
answered the cordon related relocation questions. In total 238 respondents answered the
relocation questions in relation to the cordon charge. For the kilometre charge all 422 working
respondents in the sample responded to the relocation questions. Now, the probability of
moving house due to a cordon charge may be somewhat overestimated in relation to the
kilometre charge, because only car commuters (at least one time per week) that are expected
to pass a cordon were asked to indicate the probability of relocation. In the case of the
kilometre charge all car commuters, even with shorter distances had to answer the relocation
questions. The expectation is that commuters who are not expected to pass a cordon for their
commute trip will have a lower probability of changing locations.
The probability results of searching another job are described in table 3. This probability is
significantly (statistical) higher than the probability of moving to another residential location
(for all measures). 13.5 percent of the respondents indicated that the probability is quite high,
high or extremely high and 7.3 percent reported a high to extremely high probability. The
results presented in table 2 and 3 are valid for the sample which consists partly of car
commuters who are facing delays due to traffic congestion on a regular basis (at least two
times a week with a minimum of 10 minutes) and partly of commuters possessing a car.
However, dataset characteristics in this phase have not been compared with average
