| Abstract | In modelling the choice of mode or destination, it . is
very important to understand the characteristics of the trip
makers as well as the levels of service of various competing
alternatives. Accordingly, the importance of estimating a
generalized travel distance function cannot be ignored.
Various estimates have been proposed but certain flaws in
the model structure have been found. The analysis of modal
choice has therefore given considerable problems in
modelling.
This study attempts to estimate a generalized distance
function using the Method of Maximum Likelihood. The work
and shopping trip models are of the Multinomial Legit type .
A descriptive analysis of trip maker characteristics is
also considered as an integral part of the study. The sample
data of 560 observations was taken from a survey conducted
in five destination points within the Greater Bangkok Area.
Estimation results for both work and shopping trip models
yielded rather satisfactory results with about five level of
service and socio-economic variables considered. The results
give an insight on how individual trip makers weigh the
different variables, which agree with a lot of other
existing studies on mode choice . Comfort, safety, and
reliability may indeed be important factors affecting the
use of taxi, but they cannot easily be quantified and are
more open to argument about differential perception than are
the other factors. Prediction results were quite good with
some models correctly predicting up to 92% of the actual
choice. In addition to this, bus fare elasticities were also
analyzed.
On the whole, the Logit structure satisfied its
structural diagnosis conditions. The results can therefore
be used to represent generalized distance between any two
points. The log-sum function can also be used as an
indicator of spatial separation between two points, in a
higher level of choice, e.g. destination choice. |
