基于Agent的水利水电工程施工场内交通运输仿真研究

摘要

The field transportation in the construction of hydraulic engineering plays a key role in material transportation.As the arrangement of field transportation system is complex,the field transportation simulation system is established based on Agent method.Combined with improved vehicle following strategy,the intelligence of each entity and the interactive communication between entities are realized in simulation system.As the transportation road has a large plenty of road forks,corners and steep slopes,the impact of road line on vehicle following is also considered.The case simulation shows that the number configurations of loading machinery and transportation vehicles which meet the requirements of earth-rock transportation plan can be obtained,and the traffic density and intersection queuing can also be obtained.The simulation can provide reference for construction organization design of hydraulic engineering.%水利水电工程施工场内交通道路布置错综复杂,承担着料物运输的关键作用,基于Agent方法建立水利水电工程施工场内交通运输仿真系统,结合改进的车辆跟驰策略,实现交通运输系统中各实体的智能性以及实体之间的交互通信,并针对水利水电工程中道路多岔口、多弯道、坡度大等特点,进一步考虑了道路线形对车辆运行的影响.实例表明,仿真结果可以获得满足土石流计划的配置装载机械数量及运输车辆数量、各时段内的行车密度及交叉口排队情况,可为施工组织设计提供参考.
