混合非机动车交通流路段的车道宽度设计方法

Design Methods for the Width of Non-motorized Lane in Mixed Traffic Flow Sections

针对非机动车道常呈现出自行车和电动自行车混合行驶的情况,通过对城市道路路段的混合非机动车交通流数据进行统计分析,引入混合比例范围,结合混合非机动车交通流特性,分别提出了基于流率-密度模型与基于速度-流率模型的非机动车道宽度设计方法,根据路段交通服务水平标准,得出两种设计方法的计算分析结果。研究结果表明,以上方法均可用来确定非机动车道的设计宽度且计算结果相近,基于速度-流率模型的设计方法具有较广的适用范围。

In order to research the mixed driving of bicycles and electric bicycles that is often shown in the non-motorized lanes,through the statistical analysis of the mixed non-motorized traffic flow data of urban road sections,mixing ratio range is introduced,the non-motorized lane width design methods based on the flow rate-density model and the speed-flow rate model are proposed respectively combined with the mixed non-motorized traffic flow characteristics,the calculation and analysis results of non-motorized lane width between the two methods are obtained according to the road traffic service level standards.The similar results show that the above methods can be used to determine the design width of the non-motorized lane,and the non-motorized lane width design method based on the speed-flow rate model has a wider applicable range.
