SHIFTING TO ALTERNATIVE MODELS TO REDUCE PT-SURVEYING COST BURDEN BY DOWNSIZINGTHE DATA

抄録

The shift of travel demand policies from the conventional supply oriented policies to management oriented policies has made the effectiveness of conventional trip-based modeling approaches, which still dominates the practice, questionable. In addition to this, the increasing finical burden of the conventional PT-surveying is making the sustainability of the model doubtful. The attempts so far to reduce the cost mainly focused on finding alternative surveying methods and techniques. In this paper, however, we investigate how shifting to alternative models, tour-based model in this case, may contribute in reducing the cost burden of the conventional PT-surveying approach. We will also investigate future prospect of this approach.
