| 摘 要： | 针对我国城市交通路网内机动车与非机动车混行的交通现状,提出了一种基于蚂蚁算法(ant algorithm)的寻优策略处理弹性需求下混合交通UE(user equilibrium)配流问题.同时,根据蚂蚁算法的思想以伪代码形式设计了求解弹性需求下混合交通UE配流模型最优解的程序流程,并应用于一个实例.算例表明,蚂蚁寻优策略在寻优的可靠性和计算效率方面优于传统的寻优算法. |

| Abstract: | According to the status of Chinese urban road networks containing vehicle and non-vehicle traffic flows,an optimization strategy based on the ant algorithm,is put forward to solve user equilibrium assignment problem of mixed traffic networks on elastic demands.At the same time,based on the principle of the ant algorithm's strategy,the procedure of concrete realization steps is designed for user equilibrium assignment model of mixed traffic networks with elastic demands and tested by using an example.At the end,the computation result shows that the ant colony optimization strategy outperforms the conventional optimal algorithm on the aspects of probability and computing speed. |
| Keywords: | elastic demand mixed traffic UE assignment ant algorithm |
