摘要: 通过数据融合的方法,利用交通管理系统产生的公交车运行数据和尾气排放试验产生的测试数据,以细分的 速度区间作为融合通道计算出公交车对应HC、CO、NOx排放物的分时段排放速率(g/s)和全天排放总量,并对数据 融合的原理以及适用性、代表性、融合通道的选择等问题进行了讨论。提供了可以与车流量结合,对机动车排放的 时空分布进行估算的一种方法。

Abstract: The operating data of buses generated by traffic management system and the data obtained by emission tests were used. With speed range as data fusion channel,the data were joined together by data fusion method. The emission rate( g / s) of HC,CO and NOx emissions of sub-periods and toltal emission of a day were calculated. The principle of the data fusion and the related issues such as fusion channel selection,applicability,representative were discussed. Combined with vehicle flow data,the method presented can be further used to estimate temporal and spatial distribution of motor vehicle emissions.

Key words: city buses, emission rate, data fusion
