Abstract
This study is to focuss on the necessity of the disaggregate approach for urban areas in the developing countries as a tool of urban transportation planning, then to develop some disaggregate modells by several segments for Metro Manila as a case study, finally to compare them with each other from the viewpoint of the “homogeneity” and “heterogeneity” of the mode choice behaviour revealed from sampled data. As a conclusion, the study illustrates much higher applicability of the disaggregate modelling system even with small sampling size to the whole urban area, because the colected samples can be regarded as homogenious.
