摘要：

为提高网格化机动车排放清单的精度，对时间分配模型进行改进和优化。将反应实际交通运行状况的拥堵延时指数与交通流三参数模型相结合，提出了新的基于拥堵延时指数的时间分配模型，并以济南市为验证区进行分析和验证。结果表明：经该文构建的时间分配模型分配后的污染物排放量的月、日、时的变化趋势与监测数据的变化趋势一致；基于新模型分配后的网格化NO2排放清单，采用空气质量模型（CMAQ）模拟的效果得到了显著提升，归一化平均偏差、归一化平均误差分别减少约21.6%和23.7%。该文提出的时间分配模型反应实际的交通流状况，弥补了抽样调查数据的不足，且符合交通流三参数模型，对机动车排放的精准管控、污染治理等都具有重要的参考意义。

Abstract:

The time allocation model was improved and optimized to improve the accuracy of gridded vehicle emission inventory. Based on the congestion delay index, a new time allocation model was proposed by combining the congestion delay index which reflects the actual traffic conditions with the three-parameter traffic flow model, and Jinan city was taken as the test area for analysis and verification. The results show that the monthly, daily and hourly variation trends of pollutant emissions allocated by the time allocation model are consistent with those of the monitoring data. Based on the grid NO2 emission inventory allocated with the constructed model in this paper, the simulation effect of the Community Multiscale Air Quality Modle(CMAQ) has been significantly improved, and the normalized mean deviation and normalized mean error are reduced by about 21.6% and 23.7%, respectively. The proposed time allocation model reflects the actual traffic flow situation, makes up for the shortage of sample survey data, and conforms to the three-parameter traffic flow model, showing that it has important reference significance for the accurate control of vehicle emissions and pollution control.

Key words: vehicle emission, temporal allocation, congestion delay index, gridding emission inventory
