摘要
建立了在起点交通产生总量固定和在讫点交通吸引总量固定约束下的OD分布与随机用户均衡交通分配模型,并证明了该极值模型与随机用户均衡及OD分布要求的等价性,并设计了启发式算法来求解。
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.
