自行车-行人共享道条件下自行车交通流特性研究

研究城市路内自行车一行人共享道条件下的自行车交通流特性，对城市慢行交通规划、设计和管理有重要意义。论文首先设计了共享道交通流数据的采集方案，并选择南京市5条典型的自行车一行人共享道路段展开交通调研。其次，对共享道自行车交通流基本参数进行统计分析，包括交通流量、速度、密度及空间占有量等．再次，以实测数据为基础，分别建立共享道条件下自行车交通流基本模型，以及自行车交通流基本参数之间的相互关系曲线．最后，总结分析共享道条件下交通流与传统交通流特性的主要差异性。

Characteristics of Bicycle Traffic Flow on Bicycle-pedestrian Shared Paths

It＇s very important to study the running characteristics of bicycle traffic flow under bicycle-pedestrian shared paths for urban road planning, designing and managing. Firstly, some special data collection methods were designed for study, and 5 typical links of bicycle-pedestrian shared paths were selected to perform the investigation in Nanjing city of China. Secondly, statistical analysis of some bicycle traffic parameters was done, including traffic flow, speed, density and spatial occupancy per unit. Thirdly, based on the data obtained, abasicbicycletraffic flow model and the relationship curves among the bicycle traffic basic parameters were set up respectively. Finally ,the differences between the flows on the shared paths and the bicycle-only paths were summarized and analyzed.
