Based on these crucial factors,pricing scheme is designed as the sum of basic charge fee and congestion taxes, the bi-level mathematicalprogramming is build up with multiple lower-levels. In this mathematical programming, each lower-leverprogramming, which adopts users' equilibrium model with elastic traffic demand, represents one identicalhour in a day; the upper-level programming maximizes the consumer surplus. In this model, congestion taxesare encapsulated into the river-crossing fee so that the latter could
