提出建立多尺度、多邻域规则元胞自动机模型来描述城市道路两侧人行道人非共板条件下的行人与自行车混行交通流. 人非共板是一种新颖的慢行交通管理模式，但进行这种人行道规划、设计时，指标选取往往会缺少理论支持，运营时缺乏定量评价运行状态的手段. 本文以城市道路单侧人行道板上同向行人和自行车共板的情况为研究对象，考虑自行车与行人几何尺寸、元胞状态值及邻域定义等方面的差异, 建立了统一的混合元胞自动机模型. 该模型能较好地描述这两种交通方式相互干扰现象，通过模型演化能方便地获取阻挡概率等交通运行状态评价参数，为人非共板的规划和设计提供可靠的理论依据.

Mixed Traffic Flow Cellular Automaton Model Based on Shared-Use Sidewalk

Study on the pedestrian-bicycle mixed traffic on the shared-use sidewalks beside to the street,with developing a multi-scale and multi-neighborhood-rule cellular automaton model.The shared-use sidewalk is a novel mode of non-motorized traffic management,but there is lack of theoretical support to select the plan and design parameters,lack of a quantitative method to evaluate the traffic flow state of shared-use sidewalks.The study's object is the synclastic mixed pedestrian and bicycle traffic on a single s...
