The invention discloses a method for measuring and calculating carbon emission of a motor vehicle under a road blocking condition, which is suitable for unsmooth traffic under various working conditions, such as road blocking conditions caused by intersection signal control, road maintenance construction or traffic accidents and the like, including road traffic flow conditions of free flow, limited flow, forced flow and bypass flow. According to a mode of dividing observation time periods according to specific conditions, after multiple factors such as road blocking conditions and traffic flow characteristics are analyzed, unequal time period division is carried out on the measurement and calculation time periods; traffic states are divided, speed fluctuation and inter-vehicle interference in the vehicle running process are considered, and a speed slight fluctuation influence sub-function or coefficient and a vehicle interference influence sub-function or coefficient are introduced. The carbon emission calculation is effectively simplified, parameters are simplified, and the calculation time and cost are reduced on the premise of ensuring that the calculation result is effective.
本发明公开了一种道路受阻情况下机动车碳排放测算方法,适用多种工况下的交通不畅,如交叉口信号控制、道路养护施工或交通事故等原因出现的道路受阻情况,包括:自由流、受限流、强制流和绕行流的道路交通流情况,并根据特定情况对观测时段划分的方式,分析道路受阻情况、交通流特点等多因素后,对测算时段进行不等时段划分;对交通状态进行划分,并且考虑车辆运行过程中的速度波动及车辆间干扰,引入速度轻微波动影响子函数或系数和车辆干扰影响子函数或系数。有效简化碳排放计算对参数进行简化,保证计算结果有效的前提下,降低计算时间和成本。
