摘要
为提高交通管理水平,降低城市道路交通能耗,引入了经济油耗饱和度的概念,提出了道路交通燃油经济性评价参数,研究了交通流状态与道路交通经济性的关系.在大量道路油耗实测数据的基础上,分别针对快速路、主干路、次干路、和支路建立了道路路段交通燃油经济性评价模型,并计算出哈尔滨市以上类别道路的经济油耗饱和度.验证表明,所建模型能够准确地刻画交通流状态与燃油经济性的关系,为从节能角度提高交通管理水平提供了理论依据.
In order to improve traffic management and reduce energy consumption in urban road traffic, the rela-tionship between the traffic flow status and the fuel economy of road traffic is investigated by introducing the concept of economical fuel-consumption saturation and presenting the evaluation parameter of fuel economy. Then, based on a large number of field-measured data of fuel consumption, the evaluation models of fuel economy are established respectively for expressway, trunk road, secondary trunk road and branch, and the economical fuel-consumption saturation for the above four types of roads in Harbin is figured out. The results of model validation show that the proposed models can accurately describe the relationship between the traffic flow status and fuel economy, thus providing the theoretical basis for the improvement of traffic management from the viewpoint of energy saving.
