【摘要】：為了分析城市道路車輛油耗分布特征及影響因素,以輔助交通節(jié)能減排控制策略的制定和實施,將北京市城市快速路出租車實際運行數(shù)據(jù)按道路、交通和工況條件進行劃分,以累積油耗百分比、累積運行時間百分比、相對瞬時油耗及百公里油耗為指標(biāo),利用對比分析和方差分析方法,細致研究各條件影響下出租車油耗特征.分析結(jié)果表明:道路縱坡對車輛油耗具有顯著影響,上坡相對瞬時油耗和百公里油耗較高,下坡較低;平面線形對油耗無顯著影響.路段油耗與車輛運行時間成正比,因此,緩解道路擁堵、減少行程時間將帶來較大節(jié)能效果.高速交通條件下油耗貢獻率近50%,相對瞬時油耗較高,然而其百公里油耗最低,因此,對于固定距離的出行而言,保持高速較為節(jié)能.加速工況下燃油消耗占總油耗的53%,且其相對瞬時油耗和百公里油耗也較高;勻速工況居中,保持勻速是駕駛節(jié)能的較好選擇.三因素對油耗影響程度大小為:交通條件運行工況道路條件,表明駕駛出行時,為減少行程油耗應(yīng)盡量提前規(guī)劃路線,繞避擁堵路段;同時,也表明緩解道路擁堵將能有效減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.
