摘要
该文首先结合实际调查数据对分流区交通特性进行分析研究,主要从交通流量、车速两方面;然后提出了分流区服务水平计算模型以及服务等级划分建议值;最后在交通流特性以及服务水平研究的基础上,提出了分流区通行能力参考值,并绘制分流区车速—流量曲线。
The article firstly analyzes and studies the traffic characteristics mainly from two aspects of traffic flow and vehicle speed of the distribution area according to the practical investigation data, then puts forward the service level calculation model of distribution area and the dividing proposed value of service grade,and finally puts forward the reference value of traffic capability in the distribution area and draws the vehicle speed-flow curve of distribution area on the basis of the characteristic of traffic flow and the study of service level.
