座席容量に変動がある場合の着席効用度の解析

抄録

Qualitative characteristics such as seat availability influence greatly on traveler's modal choice. The concept of Seating Utility was already proposed to evaluate commuter's train choice behaviour based on seat preference. In this paper, the method of estimating seat availability function is newly proposed, when seat capacity should vary in each train because the amount of passengers from other stations alter statistically, and commuter's real behaviour observed in middle distance commuter's station in Tokyo.It was made clear that seating utility is small value when seating time is less than about 10 minutes, but it increases rapidly with the gain of time consumption to about 30 minutes and afterwards it increases rather generously.
