【摘要】：为了更好确定混合交通中横向干扰对机动车行驶速度影响程度,明确对机动车行驶速度横向干扰的系数模型,定义了横向干扰及类型,将其划分为无干扰、摩擦干扰和阻滞干扰3种状态;通过对西安市典型路段进行实地调查获取横向干扰数据,定量分析不同横向干扰状态下,机动车行驶速度的变化趋势;以此为基础,确定不同干扰状态下对机动车行驶速度的干扰系数,以及不同干扰状态相变阈值。样本数据分析结果表明,3种干扰状态下,自行车对机动车行驶横向干扰程度存在显著差异,同时摩擦干扰和阻滞干扰状态下机动车行驶速度横向干扰系数模型显著不同。该研究成果能够有效判定自行车对机动车行驶速度的横向干扰程度,能够为设置机非隔离设施提供量化依据。
[Abstract]:In order to better determine the influence degree of lateral interference on vehicle speed in mixed traffic, the coefficient model of lateral interference on vehicle speed is defined, and the transverse interference and its type are defined and divided into non-interference. Friction interference and block interference; Based on the field investigation of typical road sections in Xi'an City, the lateral interference data are obtained, and the trends of vehicle driving speed under different lateral interference conditions are quantitatively analyzed. On the basis of this, the interference coefficient and phase transition threshold of different disturbance state to vehicle driving speed are determined. The results of sample data analysis show that there are significant differences in the degree of lateral interference of bicycle to vehicle driving under three kinds of interference states, and the model of lateral interference coefficient of vehicle speed under friction interference and block interference is significantly different. The results of this study can effectively determine the degree of lateral interference of bicycle to the speed of motor vehicles, and can provide a quantitative basis for setting up non-isolation facilities.
