中文摘要
      为准确刻画非机动车流微观运动特征,并在二维平面上描述非机动车的运动,从骑行者心理角度出发,首次提出舒适空间理论,来描述骑行者行为动机的产生,并以此为依据构建了动机 决策 执行三层框架非机动车模型,从行为产生的全过程来描述非机动车运动;将模型与上海市一处机非物理隔离路段的实证数据及现有模型进行对比,仿真结果表明,模型能够很好地反映非机动车速度分布等微观特征的同时,轨迹的平均误差仅为0.64 m,更加接近真实情况.
英文摘要
      To accurately depict the characteristics of microscopic motion, and describe two-dimensional movements of non-motorized traffic flow, the comfort-zone theory was put forward for the first time to describe the generation of behavior motivation of cyclists. Besides, based on this new theory, we proposed a three-layered model to describe the movements of non-motorized vehicles from the whole process of behaviors. Comparing with empirical data collected in a physically separated road section in Shanghai and the social force model, the proposed model can reflect the microscopic features better, and the average error of trajectories is only 0.64 m.
