为研究公交车辆在正常运营中能源消耗的影响因素，通过CAN总线数据与公交IC 卡数据 的融合，从站点间断面以及站点两个层面对北京市液化天然气（LNG） 公交车辆的能源消耗影响 因素进行了相关分析。首先分析了不同道路等级下的能耗消耗，然后利用SPSS 的相关性分析工 具对能耗的影响因素进行了分析。通过分析发现，公交车辆在公交专用道路段的行驶速度约为非 公交专用道的1.7 倍，能源消耗约为无公交专用道的70%。能源消耗由高到低依次为辅路、匝 道、主干路。同时在站点层面，车辆的能源消耗主要受到停滞时间、车辆的加减速时间、乘客的 上下车人数的影响。期望通过此项研究能够帮助公共交通的运营和规划部门制定相应的政策，以 达到减少能源消耗的同时提高公共交通运行效率的目的。

In order to study the influence factors of energy consumption of bus under normal operation, combined with the fusion of CAN bus data and bus IC card data, the influence factors of energy consump⁃ tion of Beijing LNG buses were analyzed from the two aspects: segment and station. Firstly, the energy consumption of different road grades was analyzed, and then the influence factors of energy consumption were analyzed by using SPSS correlation analysis tool. Through the analysis, the velocity of the bus when it′s on the bus lane is about 1.7 times as it on non bus lane, and at the same time the energy consump⁃ tion of the bus is about 70% of it on the road without bus lane. Energy consumption from high to low is side road, ramp and main road. At the station level, the factors influencing energy consumption are idling time, acceleration and deceleration time and number of passengers on and off. It hopes that the re⁃ search can help the public transport operators and planning departments to formulate corresponding poli⁃ cies to reduce energy consumption and improve the efficiency of public transport.
