摘要: 我国城市道路机动车道与非机动车道之间无物理隔离设施的情况非常普遍,因而相邻的机非交通流存在严重的相互干扰。本文利用石家庄市典型路段交通现场调查数据,定量分析了无物理隔离路段机动车和非机动车的速度特征。区分了非机动车道内非机动车的分布差异,通过各个典型位置非机动车平均速度的对比,解释了骑车人因受到相邻车道机动车影响而表现出的复杂交通行为;提出了基于时空转换思想的交通调查方法,建立了机动车速度的回归统计模型并通过了F检验,模型包含了非机动车流量和机非最小横向间距等参数,研究表明,机动车速度与以上参数之间呈一定的线性关系。

Abstract: It is a common phenomenon that bicyclists and motorists share the non-barrier section in urban road of China. Therefore, there exist interactions between these two participants. This research analyzes the speed characters under mixed traffic conditions by a field study in Shijiazhuang City. The difference of bicycles in the same lane is specified by the comparison of average speed, which illustrates the complicated behavior of bicyclist. Based on the idea of time-space conversion, the empirical speed model concerning bicycle flow rate and the side distance between bicycle and motor vehicle is developed using collected field data, which is accepted by F-test. On the basis of study results, it is found that a linear trend exists in the evolvement of motor vehicle speed owing to influence of bicycles.

Key words: traffic flow theory, mixed traffic, field research, regression model
