単一核都市内通勤トリップのボトルネックへの到着分布の推定

抄録

Many highway problems arise from bottleneck congestion. Regarding highway commute traffic, this analysis proposes a model which estimates the cumulative arrival curves at bottlenecks around a single core during the morning peak, given commuters' home locations and work schedules. It is necessary, therefore, to identify when and which bottleneck each commuter passes. Each commuter is assumed to have a common form of travel cost function which consists of a static cost of free flow travel time and a time-dependent cost due to bottleneck congestion. Commute trips are assigned spatially and temporally, so as to establish an equilibrium. The model is applied to the Metropolitan Expressway Network, and the estimated cumulative arrival curves reasonablly fit the observed.
