摘要
针对城市道路网络改造问题中,待改造道路和拟添加道路均具有等级选择的特点,提出了一种更加符合实际的新的网络平衡设计二层规划模型,设计了粒子群求解算法,并给出了一个简单的算例,实际算例表明该算法具有计算简单,收敛速度快的特点.
In the urban traffic network design problems, the links which will be added or improved have grade choice. In this paper, a more practical new bilevel programming model of equilibrium network design and particle swarm optimization algorithm is proposed. A simple numerical example is presented. The numerical results show that the algorithm have the characteristics of simple compute and fast convergence speed.
