| Abstract: | The influencing factors of passenger demand are analyzed.On the basis of passenger impedance functions for congested rail transit,the user equilibrium condition under elastic demand is introduced to construct user equilibrium model for rail transit.According to the characteristics of model,a revised Frank-wolfe algorithm is given to establish a rail transit user equilibrium model under elastic demand.Finally,a numerical example is used to show that the proposed model and algorithm are rational and effective. |
