摘要
提出了适用于大规模网络的组合随机用户平衡模型,能够同时预测出行分布和交通分配。因为出行分布、交通分配子模型都是建立在随机效用理论基础上,因此,整个模型具有一致性,且具有很好的行为解释。引进循环优化分配算法,并用一个简化的例子对模型及算法进行了验证说明。
A combined stochastic user equilibrium model for simultaneous prediction of trip distribution and trip assignment on large-scale networks is developed. Because both the trip distribution sub-model and the trip assignment sub-model are based on random utility theory, the model has consistent and behavior richness. The iteration-optimization assignment algorithm for solving the combined stochastic user equilibrium model is introduced. The proposed model and algorithm is illustrated with a simple numeral example.
