【摘要】：为优化城市道路网络布局,以若干个城市高德地图实时路况的交通出行数据为基础,研究了主干路、次干路、支路等不同等级道路的路段状态相关性,设置了考虑相关性的道路间距,计算了城市路网密度与等级级配。分析结果表明:主干路和主干路、主干路和次干路、主干路和支路相关单元的平行距离均服从对数正态分布,平行距离的85%分位值分别为2.4、1.0、0.9km;主干路间距取为2.4~2.5km,主干路间设置2条次干路,次干路与主干路的间距为0.8~1.2km,支路间距为0.2km或0.3km;次干路和支路对应平行距离的85%分位值比较接近,实际路网中次干路和支路的功能区分尚不明确。所得路网结构布局符合相关性、路网密度与等级级配的要求,可为路网规划提供参考。
[Abstract]:In order to optimize the layout of urban road network, based on the traffic trip data of the real time traffic condition of Amap in several cities, this paper studies the correlation of road sections of different grades, such as main road, secondary trunk road, branch road and so on. The density and grade gradation of urban road network are calculated. The results show that: main road and trunk road, trunk road and secondary trunk road. The parallel distance of the main road and branch unit was distributed from the logarithmic normal distribution, the value of the parallel distance of the parallel distance was 2. 4 / 1. 0. 0 ~ 0. 9 km, respectively. The distance between the main roads and the main roads is 2. 4 ~ 2. 5 km, and the distance between the main roads and the main roads is 0. 8 ~ 1. 2 km and 0. 2 km or 0. 3 km respectively, and the distance between the main roads and the main roads is 0. 2 km or 0. 3 km. The value of 85quartile corresponding to parallel distance between secondary trunk road and branch road is relatively close, and the functional distinction between secondary trunk road and branch road in actual road network is not clear. The requirement of network density and grade gradation can provide reference for road network planning.
