【摘要】：为了分析城市道路车辆油耗分布特征及影响因素,以辅助交通节能减排控制策略的制定和实施,将北京市城市快速路出租车实际运行数据按道路、交通和工况条件进行划分,以累积油耗百分比、累积运行时间百分比、相对瞬时油耗及百公里油耗为指标,利用对比分析和方差分析方法,细致研究各条件影响下出租车油耗特征.分析结果表明:道路纵坡对车辆油耗具有显著影响,上坡相对瞬时油耗和百公里油耗较高,下坡较低;平面线形对油耗无显著影响.路段油耗与车辆运行时间成正比,因此,缓解道路拥堵、减少行程时间将带来较大节能效果.高速交通条件下油耗贡献率近50%,相对瞬时油耗较高,然而其百公里油耗最低,因此,对于固定距离的出行而言,保持高速较为节能.加速工况下燃油消耗占总油耗的53%,且其相对瞬时油耗和百公里油耗也较高;匀速工况居中,保持匀速是驾驶节能的较好选择.三因素对油耗影响程度大小为:交通条件运行工况道路条件,表明驾驶出行时,为减少行程油耗应尽量提前规划路线,绕避拥堵路段;同时,也表明缓解道路拥堵将能有效减少道路交通能耗排放.
[Abstract]:In order to analyze the distribution characteristics and influencing factors of fuel consumption of urban road vehicles and to assist in the formulation and implementation of traffic energy saving and emission reduction control strategies, the actual operation data of urban expressway taxis in Beijing are classified according to road, traffic and working conditions. Taking cumulative fuel consumption percentage, cumulative operation time percentage, relative instantaneous fuel consumption and 100 km fuel consumption as indexes, the characteristics of taxi fuel consumption under the influence of various conditions were studied by means of comparative analysis and variance analysis. The results show that the longitudinal slope of the road has a significant effect on the fuel consumption of vehicles, the relative instantaneous fuel consumption and 100 km fuel consumption of the uphill slope is higher than that of the lower slope, while the plane alignment has no significant effect on the fuel consumption. The fuel consumption of the road section is proportional to the running time of the vehicle. Therefore, alleviating the road congestion and reducing the travel time will bring about a greater energy saving effect. Under the condition of high-speed traffic, the contribution rate of fuel consumption is nearly 50%, and the relative instantaneous fuel consumption is relatively high. However, the fuel consumption of 100 km is the lowest. Therefore, it is more energy-saving to keep the high speed for the travel with fixed distance. Fuel consumption accounts for 53% of the total fuel consumption under accelerated operation, and its relative instantaneous fuel consumption and 100 km fuel consumption are also higher. The influence degree of the three factors on fuel consumption is as follows: traffic condition operating condition road condition indicates that in order to reduce travel fuel consumption we should plan the route ahead of time and avoid the congestion section as far as possible; At the same time, it also shows that reducing road congestion will effectively reduce the energy consumption emissions of road traffic.
