基于车辆自动定位数据的有轨电车运行效率分析与应用

结合有轨电车线路的现有车辆自动定位数据,分析有轨电车运行效率及其相关影响因素。其中,影响因素从站台、路段、交叉口3个方面进行考虑。定性分析了不同站台型式、站台位置、交叉口类型的属性特征,并量化不同路段的路段长度、所包含的交叉口个数,同时考虑了交叉口控制策略对有轨电车运行时间的影响。以某已运营的有轨电车线路为例,通过建立多元线性回归模型,从不同层面探究不同因素对已运营有轨电车线路运行效率的影响。最后用模型对有轨电车新建线路的运行效率进行预测,并提出建议。

Analysis and Application of Tram Operation Efficiency Based on AVL Data

Based on the existing vehicle automatic positioning data of tramcar lines,the tramcar operation efficiency and the related influencing factors are analyzed and classified from platform,line section and intersection three aspects.Then,the attribute characteristics of platform,platform positions and intersection types are qualitatively analyzed,the lengths of different line sections,the number of intersections in different intervals are quantified,the influence of intersection control strategy on the travel time of tramcar is also taken into consideration.Based on the practical operation of a tramcar line,the influence of different factors on tramcar operation is analyzed from different levels by establishing a multiple linear regression model,which is finally used to predict the operation efficiency of new tram lines.
