【摘要】：為了更好確定混合交通中橫向干擾對機動車行駛速度影響程度,明確對機動車行駛速度橫向干擾的系數(shù)模型,定義了橫向干擾及類型,將其劃分為無干擾、摩擦干擾和阻滯干擾3種狀態(tài);通過對西安市典型路段進行實地調(diào)查獲取橫向干擾數(shù)據(jù),定量分析不同橫向干擾狀態(tài)下,機動車行駛速度的變化趨勢;以此為基礎(chǔ),確定不同干擾狀態(tài)下對機動車行駛速度的干擾系數(shù),以及不同干擾狀態(tài)相變閾值。樣本數(shù)據(jù)分析結(jié)果表明,3種干擾狀態(tài)下,自行車對機動車行駛橫向干擾程度存在顯著差異,同時摩擦干擾和阻滯干擾狀態(tài)下機動車行駛速度橫向干擾系數(shù)模型顯著不同。該研究成果能夠有效判定自行車對機動車行駛速度的橫向干擾程度,能夠為設(shè)置機非隔離設(shè)施提供量化依據(jù)。
[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.
