摘要
利用变分不等式建立基于Kirchhoff分布交通分配模型,并证明模型的解满足Kirchhoff分布路径选择概率表达式,基于K最短路算法和连续平均法,设计求解模型算法。并与基于logit加载随机用户均衡交通分配模型作比较,对同一个虚拟路网进行求解,结果表明基于Kirchhoff分布分配模型不仅能够较好地考虑路径成本相对差对出行者路径选择行为的影响,并且模型达到收敛标准所需的迭代次数大大减少。
The research establishes the Kirchhoff based traffic assignment model and proves that the solution fits the Kirchhoff probability expression. A logit based SUE traffic assignment model is used to make comparison with the model established by the paper, using the same experimental road network. Results show that the Kirchhoff based model can better consider the influence on route choice behavior caused by the relative differences among route travel times, and the model needs far less iterations before it meets the convergence criterion.
