不同行驶条件下公交振动舒适性的影响因素研究
Factors Influencing the Vibration Comfort of Public Transportation under Different Driving Conditions
摘要
Abstract
In order to enhance passenger ride comfort,based on the three-axis acceleration data of bus movement,the effects of external environmental factors such as the number of one-way lanes,the number of bus stops,the number of signal-controlled intersections,the presence or absence of motor-nonmotor sep-aration barrier,and the presence or absence of bus-only lanes on the vibration comfort of buses were ex-plored by using ordered Logistic regression,and the influence degree of the type of station on the comfort was quantitatively evaluated for the first time by using binary Logistic regression.The analysis finds that:the probability of experiencing very uncomfortable conditions on roads without a barrier separat-ing motor vehicle lanes from non-motorized lanes is 3.5 times higher than on roads with such a barrier;The mean weighted acceleration has decreased by 18%with the increase in the number of unidirection-al lanes,which significantly reduces the comfort of ride;The probability of being very uncomfortable for buses stopping at a harbor-type platform is 24.6 times higher than for buses stopping at a straight-type platform.The study shows that the installation of barriers separating motor vehicle lanes from non-motorized lanes can significantly reduce the impact of non-motorized vehicles and pedestrians on buses and optimize the efficiency of bus operation;Increasing the number of unidirectional lanes can reduce traffic delays due to frequent lane changes,and thus improve the comfort of ride;In particular,it should be noted that harbor-type platforms bring passengers a very uncomfortable riding experience,and reducing the establishment of harbor-type platforms is the key to improving the quality of bus ser-vice and enhancing the attractiveness of buses.关键词
