摘　　要：在我国城市交通管理中,对城市信号交叉口处机动车、自行车和行人的混合交通流的有效组织是交通通畅运行的关键。在交通调查的基础上,利用数理统计方法分析城市信号交叉口自行车及行人的到达与释放规律,提出城市信号交叉口自行车及行人的到达分布模型,对城市信号交叉口自行车流的释放饱和流率、释放速度和行人步速进行标定,并对信号交叉口自行车流及行人的交通特性形成原因进行分析。研究结果可应用于城市信号交叉口混合交通控制及管理。Effectively managed mobile,bicycle and pedestrians mixed traffic flow at signalized intersection is a key to traffic management in China.This paper analyzes bicycle and pedestrian's arrival and departure characteristics at signalized intersection using statistics method based on traffic investigation,establishes bicycle and pedestrian's arrival models at intersections,calibrates the bicycle's departure saturation flow,departure speed and pedestrian's velocity.This paper also analyzed why mixed traffic flow have these characteristics.We can apply the results to traffic control and management.
