A Note on Trip Benefits in Spatial Interaction Models
扩展了Williams（1976）提出的双重约束空间交互模型中的交通用户效益度量，将效益与出行而非区域关联，并推导了长期情况下的公式，更新了区位行为的可达性度量。
We extend the well‐known transport users' benefits measure (TUB) for the doubly‐constrained spatial interaction model derived by Williams (1976). The original formula expresses the TUB as composed by two terms associated with the origin and the destination zones. First, the TUB is associated here with trips instead of zones, providing a natural interpretation as a rule‐of‐a‐half measure of benefit under inelastic demand (for the short‐run case). Second, a TUB formula for the long‐run case is derived, that is, when the total number of trips, trip origins, and trip destinations change. We then propose updated measures of accessibility for location behavior.
