The congestion of toll plaza seriously damages safety and smoothness of highway.In order to induce driver to reasonably choose charging channels, to improve the efficiency of toll station, and to relieve the congestion problem of highway toll plaza, this paper, considering drivers as the object of study and using evolutionary game approach, obtains two evolutionary stable strategies under different cost conditions by establishing game pay-off matrix, which can verify that there is equilibrium existing in the game of toll channel selection of drivers.Finally ， some specific measures are proposed to balance the distribution of traffic flow of the toll plazas.Study shows that mixed strategy is equilibrium of game; to refine the functional area of toll plaza, to arrange quantity of charging channel reasonably and to allocate the vehicles in weaving section rationally are beneficial to induce strategic choices of drivers to be near the equilibrium, which efficiently relieves the congestion of the toll plazas.
