No-Wardrop-equilibrium theory is introduced into this paper. An analysis is made of the road-net systemic welfare when the fixed user and elastic user are coexisting in congestion-pricing. Result shows that the elastic user is an efficient colony on an inferior position while the fixed user is an inefficient one but on a preponderant position. The paper illustrates the negative effect of enterprisevehicle on implementing congestion pricing strategy with a theoretic analysis and an example, controlling of the numbers of enterprise-vehicle or changing enterprise-vehicle choice rule on the basis Of the Wardrop-equilibrium theory will be helpful to the road-net systemic welfare.
