Intrazonal trips are not always included in model estimation because they do not
appear on a network in centroid-to-centroid travel. It is also presumed that their
exclusion does not affect model results. This paper tests the above presumption by
examining the assumptions of ignorable missingness. The results indicate that
omitting intrazonal trips in model estimation result in biased sample. Consequently
parameter estimates get biased. The paper also compares the results of travel mode
choice models by excluding and including the intrazonal trips in model estimation.
