    Abstract
  • The dynamic congestion pricing problem of combined travel was studied in multi-class network with elastic demand by using dynamic transportation assignment theory and stochastic utility theory. The assumptions that all users were homogeneous and total travel demands were all the same were released. A variational inequity model satisfying the dynamic combined travel conditions was proposed, a bi-level dynamic congestion pricing model was established and its solution algorithm was designed. Analysis result shows that the congestion pricing is very effective to reduce the departure rate during peak hours by means of transferring some flows from peak hours to off-peak hours. It has greatest impact on the travelers with low values of time because these travelers would probably change their departure time choices and route choices to avoid the payment of congestion pricing. The total social welfare increases after the implementation of congestion pricing, so the congestion pricing can improve the congestion situation of some links and optimize the whole service efficiency of traffic system.
