4.2 Explanatory characteristics for relocation choice
4.2.1 Residential relocation
Table 6 gives the results of an ordered probit analysis aimed at getting insight into
explanatory variables for the probability of moving to a residential location closer to work due
to the introduction of a kilometre charge. For the analyses the relocation probabilities
observed for the first three pricing measures (see table 1) were combined. Explanatory
variables for the cordon charge are not presented in this paper (i.e. measures 4 and 5).
Furthermore, to be able to study the explanatory characteristics of changing locations
specifically initiated by a road pricing measure, respondents that indicated to have a
moderately high, high or extremely high possibility of changing their residential location
within 2 years (for whatever reason) were removed from the dataset. In total a range of about
30 variables were tested on significance. The variables consisted of various socio-economic
characteristics (e.g. income, household size, age, education level) and furthermore of other
household related and various trip and price measure related characteristics. Finally also
attitudes and perception characteristics were tested. Only variables significant with a
reliability of at least 90 percent are presented in the table.
