Final Analytical Comparison of Aggregate and Disaggregate Mode Choice Models Transferability

Transportation models as tools for transportation planning are critical to such related decisions. considering the highcost of calibrating and validating such models, effective alternatives are highly sought for; one such alternative beingthe use of models calibrated for other cities. this calls for transferability analysis which has not been the subject ofmany researches. due to criticality of aggregate and disaggregate data in transportation models, this paper tries tocompare transferability of models calibrated with data of both groups. mode choice models for daily work trips in tworeal-sized cities of qazvin and shiraz are analyzed. models are calibrated employing multinomial logit structure withfour modes of private car, taxi, bus, and 2-wheelers. in order to increase reliability of results, the top five best modelsare selected for each city-data category to be transferred. based on transferability test statistics, transfer index, andgoodness-of-fit of transfer models, aggregate models are not transferable and their results are deceptive. transferabilitymeasures of these models are not in acceptable range; whereas transferability of disaggregate models have relativeproper response. according to transfer index and goodness-of-fit of origin models operate similar to destination models.however transferability test statistics rejects the assumption of equality coefficients in both cities models. usingpersonal variables helps to effectively transfer origin models in addition to improve them.
