Understanding the process of decision-making by which an individual chooses amode is important for researchers in constructing disaggregate behaviormodels. Most of the existed researches assumed that all individuals use thesame decision rule,or seperated them by an attribute and, futher, explainedone''s decision rule by this attribute.In this study,we try to use two kinds ofchoice model:compensatory model and non- compensatory model to make a researchabout one''s choice behavior.Using two classified rules:outer-classificationand inner-classification,this study develops a multi-attribute decision tree,and according to the classified result of this decision tree,we can explainone''s decision rule(compensatory or non-compensatory) under different kinds ofsocial background and travel circumstance.Using the intercity travel data of Taiwan in 1996, this study built the hybridchoice models including compensatory and non-compensatory decision rules. Multinomial logit (MNL) model and Elimination by aspects (EBA) model were usedto construct these two kinds of decision rule models in this study, and thepredictive strength and percent correctly predicted were used asmeasurements. The empirical results found the following conclusions:1.Classified models have better statistic performance than non-classifiedmodels. 2.Non-coessential groups will use different decision rules.Travellerswho are younger, with lower income, on non-bussiness trip,or not in a hurrytend to use compensatory decision rule.Contrastly, travellers who are older,with higher income, on bussiness trip , or in a hurry tend to usenon-compensatory decision rule. 3.Non-coessetial groups differ in modalchoice.Most of travellers who tend to use compensatory decision rule choosetrain or bus.Contrastly, travellers who tend to use non-compensatory decisionrule choose airplane mostly. 4.As to the viewpoint of modal attributes, travellers are different from each other.Cost and convenience are moreimportant to those who tend to use compensatory decision rule.In contrast,travellers who tend to use non- compensatory decision rule consider timespent preferentially.
