Transferability and updating of disaggregate travel demand models motorcylcle dating sites
Thus, separate models for home- based trips and nonhome-based trips are developed, without any consideration of the dependence between these categories of trips.
Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages. The influence of the size of the appli- cation context data on transferability was also examined by using five different samples. âExplanatory and Forecasting Capabilities of Trip Distribution Models.â Canadian Journal of Civil Engineering, 13, pp.
However, like the earlier trip distribution models, Karasmaa and Pursula also confined their attention to home-based work trips in the paper.
In contrast, Karasmaa and Pursula (1997) examined temporal transferability in the context of a dis- aggregate nested logit trip destination-mode choice model, which effectively considers travel time and cost characteris- tics by multiple modes (walk, car, and public transport) in destination choice decisions. âTransferability of Disaggregate Mode Choice Models.â Regional Science and Urban Economics, 5, pp.
The authors examined the effects of model specification by using travel time and travel-cost variables only, and then adding the number of cars per household as an additional socio- economic variable.
The research is based on data from the Helsinki metropolitan area, collected in 1981 (estimation context) and 1988 (transfer context).
However, this result did not carry over to transferability as measured by the zone-level root mean square forecast errors. âEvidence on Transferability of Trip Generation Models.â Journal of Transportation Engineering, Vol.
