本文基于北京市出租车实际运行数据,研究城市快速路基本路段不同工况、服务水平下驾驶行为对出租车油耗的影响,分析各条件下生态驾驶节能潜力.应用方差分析方法,分析不同条件下驾驶行为对出租车油耗的影响.研究结果表明,出租车在城市快速路基本路段加、减速频繁;随服务水平提高,加速、匀速工况下车辆油耗升高,减速工况下车辆油耗降低;低服务水平下加速工况油耗是车辆油耗的主要来源.考虑各条件下油耗对出租车总油耗的贡献,提出生态驾驶行为节能潜力计算方法.分析结果表明,加速工况下生态驾驶节能潜力最高,出租车在快速路基本路段取生态驾驶行为的综合节能潜力可达11.18%.

Taxi actual operating data on Beijing urban basic freeway section is taken and then divided according to driving cycle and level of service(LOS), based on which the effect and potential to fuel consumption of eco-driving under different conditions is analyzed. Analysis of variance (ANOVA) is used to analyze the effect to fuel consumption of driver behavior under different conditions. The result shows that taxis accelerating and decelerating are frequently on urban basic freeway section. With the improvement of LOS, taxi fuel consumption is increased under the condition of acceleration and steady running, but it is reduced under deceleration. The main vehicle fuel consumption comes from the accelerating process at low LOS. Considering the conditions' contribution to total fuel consumption, eco-driving fuel-saving potential calculation method is proposed to analyze benefits of eco-driving. It turns out that accelerating process has highest fuel-saving potential and the whole fuel consumption reduction on urban basic freeway section could be 11.18%when adopting eco-driving.
