在评价由道路系统以及交通量的改变而引起的交通行为特征变化时,交通微观仿真模型正迅速地成为首选的工具。交通微观仿真模型与传统分配模型在建立、产生结果和报告等方面存在某些共性,但也有很多不同之处。从对数据要求的讨论到模型的建立,介绍了应用微观仿真模型的全过程,并探讨了如何使用微观仿真模型对不同设计方案进行评价,进而分析各方案所产生的效果。
Traffic micro-simulation models are rapidly becoming the tool of choice when assessing changes in traffic behavior caused by changes in road systems and traffic volumes. There are some commonalities between traffic micro-simulation model and traditional allocation model in establishing, producing results and reporting, but there are also many differences. From the discussion of the data requirements to the establishment of the model, the whole process of applying the microscopic simulation model is introduced, and how to evaluate the different design schemes by using the microscopic simulation model is discussed. Then the effect of each scheme is analyzed.
