　　Link capacity refers to the maximum flow that can pass through a link during an hour. For dynamic travel choice models, link capacity constraint may impose on link inflow or outflow. Though link inflow capacity constraint has been studied in previous literature, link outflow capacity constraint is more rational and in accordance with real situation. In this study, link outflow capacity constraint is included in a dynamic model, which is then solved by a proposed algorithm. Numerical examples show that dynamic equilibrium conditions are fully complied, but with higher computation time as compared with the link inflow capacity model.
