Calibration Of A Florida Nested-Logit Mode-Choice Model


This paper describes the development of a mode choice model for Florida. Data from the 1999 travel survey conducted in Southeast Florida were used in the calibration of the model. The calibration also involved travel times and costs of the highway and transit systems obtained from the skim files of the Southeast Florida model. The mode choice model was estimated as a three-level nested logit structure. Two separate surveys were used in the estimation process. The first is the on-board transit survey, and the second is the household survey. The portion of the nesting structure that includes the different transit alternatives (the transit branch) was estimated using the on-board transit data, while the upper nest that includes the choice of transit versus highway used the household travel data. The two models were linked through the use of the inclusive value of transit. The inclusive value of the transit system was defined to represent the aggregate utility of using the transit system. Both models were calibrated using the full information maximum likelihood (FIML) approach. Among the significant variables that entered into the model are; transit access time, transit wait time, number of transfers, in-vehicle travel time, fare, and household car ownership.
