A structural model is provided for traffic assignment to a transit model. It deals with a hierarchy of layers from passenger to network passing by vehicle, service route and line, while taking advantage of the spatial structure of service routes and lines. A range of capacity effects are addressed: in-vehicle passenger capacity, access-egress capacity in relation to dwelling time, platform occupancy by vehicles which may reduce service frequency. The model treatment involves a line sub-model, which amounts to a sophisticated cost-flow relationship, and platform sub-models first for passenger storage and flowing, second for vehicle operations. Traffic equilibrium is addressed in a hyperpath framework on the basis of leg links.
