基于多尺度融合的城市交通路网仿真系统研究

摘要

City traffic simulation research is more, but there are some problems that transportation systems in spatial scales are integrated from the micro to the macro highly, and complexity of the traffic system determines any of a single-scale integration is difficult to make better objective simulation to transport phenomena. On this basis,proposed a simulation system based on multi-scale fusion to use the corresponding algorithm do integration from the macro, meso and micro scale and system desiga Finally, this paper made experiments the city traffic network optimization simulation system based on multi-scale fusion. The experiment proves the usefulness and reliability of the system.%目前关于城市交通仿真方面的技术研究较多,但都存在一些问题,如:交通系统大部分在空间尺度上是从微观到宏观的高度综合,在时间尺度上是从秒级到年级高度连续的整合,交通系统的复杂度决定了任何一种单一的尺度都很难对交通现象进行更好的客观仿真.在此基础上,提出了基于多尺度融合的仿真系统,旨在从宏观、中观、微观3个尺度运用相应算法进行融合,并对系统进行设计.最后对基于多尺度融合的城市交通路网优化仿真系统进行实验,通过南京福建路和三牌楼路口信号方案优先的实例对其进行路网仿真实验分析.结果证明,该系统具有实用性和可靠性.
