Book Description
Disaggregate mode choice models were calibrated for intercity passenger travel in Canada using a data base drawn from the Canadian Travel Survey. The purpose of the work was to evaluate the feasibility of developing disaggregate models for intercity travel using an existing Canadian data base. Multinomial logit models were calibrated for business and nonbusiness trips in the eastern and the western regions of Canada. The calibrated models produced reliable results in terms of goodness-of-fit measures. The likelihood ration index, p2(c), varied from0.282 to 0.436. Results obtained were comparable to those of previous studies. The research identified the significance of level-of-service factors in determining mode choice. The findings from the study indicated that the Canadian Travel Survey data could be used for developing dissagregate models for possible use in policy impact analysis. The potential for the use of this data base in the transportation planning process could be enhanced if some relatively minor modifications were made.

Book Description
In many transportation studies, the time span of data collection, model development, and analysis is often too long to be responsive to the needs of policy analysts and decision makers. This problem is often exacerbated in situations with severely constrained anlaysis resources. Therefore, it is often useful to transfer a model from one area to another. Model transfer is deifned as the application of a model developed in one area to describe the corresponding behavior in another area. This paper examines the transferability of a class of models used in intercity travel demand analysis. Specifically, deisaggregate mode choice models of the multinomial logit type are developed for two regions in Canada, and some established measures of tranferability are applied to assess the potential of calibrating these models in one region and applying them in the other. comparison of mode choice models estimated on data sets from the two regions yielded inconclusive results regarding model transferability. In general, transferred models were found to be 18-23% less accurate than local models in predicting modal shares. Adjusting models; parameters to reflect observed modal shares in the application context improved the predictive ability of the models by about 10%.
