| 摘 要： | 针对以往城市路网交通状态评价研究中大多从中观角度将路口归入路段而忽略了交叉口对路网交通状态影响的问题,选取交叉口进口饱和度和路段平均行程速度作为路网状态评价的基本参数,将宏观路网交通状态评价与微观交通状态分析相结合,定义了一种新的路网交通状态系数,作为交通畅通行驶的阻抗,研究确定了路网交通状态系数临界值,提出了一种新的...

| Abstract: | To cope with the problem that intersection was put into road sections more from the meso perspective while ignoring the effect of intersection to traffic network state in previous studies of urban traffic network state evaluation,the basic parameters of traffic network state evaluation such as intersection entrance saturation and mean space speed of road sections were chosen,combining the macro road network state evaluation and microscopic traffic state analysis,a new traffic network state coefficient was d... |
