摘要
我国城市非机动道路内的交通现象通常为电动自行车与人力自行车混合行驶状况,车速离散是该类道路内交通流的重要特征。结合杭州市的调查数据,采用统计学方法定量分析混合非机动交通流车速离散特性,分别建立车速离散特性评价参数与各主要影响因素之间的回归关系。结果表明,归一化车速离散度分别与各影响因素成线性回归关系;除电动自行车比例因素之外,车速变异系数与其它各因素成线性回归关系。
Traffic phenomena on urban non-motorized roads in China are usually the mixed driving conditions of electric bicycle and manpower bicycle.Speed discrete characteristics is the main feature in this kind of mixed flow.Vehicle speed dispersion is an important feature of the mixed flow on such roads.Based on the field data in Hangzhou,the regression models were established to determine the relationship between the main influencing factors and the evaluation parameters of speed dispersion characteristics,respectively,by using statistical method.The results show that there is linear regression relation between the normalized vehicle speed dispersion and each influencing factor,respectively.There is also linear regression relation between the coefficient of speed variation and each influencing factor except the proportional factor of electric bicycle,respectively.
