| Abstract: | O-D distribution and stochastic equilibrium assignment combined optimal model is established in this paper under the condition of constant origin productions and destination attractions. The equivalence of solutions to proposed model with stochastic user equilibrium assignment and O-D distribution requirements is proved by constructing proper lagrangian function. Then heuristic algorithm is designed to solve the built model. |
