城市公交线路模态工况构建方法研究

采用GPS设备对西安城市公交典型线路的运行工况进行实测,分别运用瞬态转模态方法和多目标优化法构建出城市客车模态工况。以8个特征参数相对误差为标准,对两种方法的精度进行了对比研究。研究表明,两种方法均能有效地完成工况构建,其中多目标优化法精度最高,瞬态转模态方法简单快捷,从而为工况构建方法的选取提供了思路和数据验证。

Development of Mode Driving Conditions for Urban Bus Lines in Xi'an

The operating conditions of typical city lines in Xi'an were measured by GPS equipment,the transient to modal method and the multi-objective optimization method are used to construct the modal operating conditions of the city bus.The relative errors of eight characteristic parameters are used as the standard to compare the accuracy of the two methods.The results show that methods can effectively complete the construction of working conditions,the multi-objective optimization method has the highest accuracy,and the transient to modal method is simple and quick,which provides ideas and data verification for the selection of the construction method of working conditions.
