【摘要】：伴随着城市化进程的迅速发展,城市范围不断扩大,原来毗邻城市的乡村地区从以农业为主的单一土地利用形式转变为工业、商业、住宅及其他用地的混合土地利用形式,同时城市基础设施不断丰富,形成了城乡结合部这一区域。由于不同的土地利用形式对于接入道路的需求不同,因此城乡结合部道路接入口的形式也十分多样。国内目前的设计规范和准则对于道路接入口并未有系统性的规定,一定程度上导致了城乡结合部道路接入口的无序建设,降低了城乡结合部道路的通行能力和安全性。本文以提升城乡结合部道路的通行能力和安全性为目标,对城乡结合部道路接入口的优化布设方法进行了研究。首先,通过查阅国内外相关文献以及实地调查获取相关数据,分析了城乡结合部道路接入口处的车辆行驶特征以及冲突数据,对城乡结合部道路接入口进行了分类,运用数理统计方法分析论证分类的合理性。然后,探讨了各等级道路的接入口设置原则,研究了接入口之间以及接入口和交叉口之间的合理间距,提出了接入口的选位范围。其次,研究了接入口的几何设计,包括接入道路长度、接入口交通组织设计、接入口开口宽度和接入口处的转弯半径等,讨论了在接入口设置密集的不利条件下布设接入口的方法。最后,结合实例给出了具体的改善措施,并运用VISSIM以及SSAM对改善措施进行了论证,评估了改善措施的有效性。
[Abstract]:With the rapid development of urbanization, the urban scope is expanding, and the rural areas of adjacent cities have changed from a single form of land use dominated by agriculture to a mixed form of land use for industrial, commercial, residential and other land use.At the same time, the urban infrastructure continues to enrich, forming the urban-rural junction of this region.Because different land use forms have different demand for access roads, the access access forms of urban and rural areas are also very diverse.There is no systematic regulation on the road junction entrance in the current design code and criterion in China, which to some extent leads to the disorderly construction of the road junction entrance in the urban-rural joint area, and reduces the capacity and safety of the road in the urban-rural junction area.In order to improve the capacity and safety of the roads in the urban-rural junction, this paper studies the optimal layout method of the road entrance in the urban-rural junction.First of all, by consulting domestic and foreign relevant literature and field investigation to obtain the relevant data, analyzed the vehicle driving characteristics and conflict data at the road junction entrance of the urban and rural areas, and classified the road junction entrance of the urban and rural areas.The rationality of classification is proved by mathematical statistics.Then, the principle of connecting entrance is discussed, the reasonable distance between entrance and intersection is studied, and the selection range of entrance is put forward.Secondly, the geometric design of the entrance is studied, including the length of the access road, the traffic organization design of the entrance, the width of the opening and the turning radius of the entrance.This paper discusses the method of arranging the connection entrance under the unfavorable condition of dense connection entrance.Finally, the concrete improvement measures are given with examples, and the improvement measures are demonstrated by VISSIM and SSAM, and the effectiveness of the improvement measures is evaluated.
