小城镇摩托车折算系数研究

Research on motorcycle conversion coefficient in small towns

根据小城镇中小汽车和摩托车混行的道路特征,建立了延误流量的非线性关系模型,并利用实测数据采用回归方法对问题进行求解.通过对实测数据进行计算分析得到小城镇摩托车的折算系数随着摩托车混入率的变化关系,并给出小城镇摩托车的折算系数建议取值.实验结果表明:研究提出的小城镇摩托车混行折算系数模型具有较好的鲁棒性,适用于小城镇交通系统.

According to the feature of car-motorcycle mixed on the road, the nonlinear model for delay-flow was estab- lished, the problem was solved by regression method using the measured data. The conversion coefficient of small town motorcycle along with the different motorcycle mixing rate was obtained through calculation and analysis of measured data, therefore the recommended values of conversion coefficient for small towns had been given. Experimental results demon- strated that the conversion coefficient model which the study informed had good robustness and was applicable to small town traffic system.
