The attributes that influence an individual’s commuting choice may be very complex. Observed
heterogeneity labelled traditional objective choice attributes are able to be incorporated easily into
choice models. However, there are also latent heterogeneities that are often overlooked by traditional
thinker’s transport modellers. This paper deals with the issue of structuring the influence of these
latent factors. Six latent factors are considered in grouped under three broad categories: attitude,
perception and preference, together with traditional objective choice attributes. After evaluating the
indicators of latent factors by factor analytic models, MIMIC structural modeling was employed to
analyze the relationship among the latent factors, and between latent factors and objective attributes.
All indicators and factors were found to be significant and the model fitted data reasonably well with
the evidence of minimal capacity of objective attributes representing latent aspects those are
significantly responsible 89.9% to structure the traveller’s choice preference.
