traffic composition meaning in English

又称“设计车速”。交通组成

At last , based on the feature integrating traffic simulation with traffic assignment , the paper compares the link volume by using different traffic assignment models , and analyzes the influence of user equilibrium and system ' s optimal assignments on travel time , travel speed as well as traffic volume on links . further , the paper introduces the study on the influence of traffic composition on road link dynamics and the traffic simulation application in formulating dynamic traffic assignment models
最后利用urbansim模型中交通仿真与交通分配相结合的特点，对比研究不同的交通分配方法在仿真模拟中路段产生的交通量，分析了交通分配中用户平衡和系统最优原理对路段行驶时间、行驶车速的影响，并进一步研究了交通量构成对路段动态特征指标的影响，以及利用交通仿真系统尝试在动态交通分配中进行应用研究。
