摘　　要：为研究公交车辆在停靠站停靠时尾气排放的规律,文章通过现场调查公交车停靠过程,使用MOVES2014a模型对公交停靠过程中尾气污染物(包括主要三种尾气污染物CO、NOx、HC)的排放规律进行模拟仿真模拟。发现在停靠过程中,三种排放物中NOx排放量最大,并随着速度的减小各污染物排放因子不断增大,尤其在怠速阶段公交车尾气排放量达到最大。在三种运行工况下,怠速工况对公交车尾气排放影响最大,加速工况下次之,减速工况下最小。In order to study the emission law of bus exhaust during parking, this paper investigates the process of bus parking on the spot, and simulates the emission law of exhaust pollutants (including CO, NOx, HC) in the process of bus parking using MOVES 2014a system. It is found that among the three emissions, NOx emission is the largest in the process of bus parking. As the speed decreases, the emission rate of pollutants increases, especially in the idle stage, the emission of bus exhaust reaches the maximum, and the idle situation caused by repeated car-following will significantly increase the time of the whole parking process, resulting in the increase of bus exhaust emissions. In order to study the emission law of bus exhaust during bus stopping, this paper investigates the process of bus stopping on the spot and simulates the emission law of exhaust pollutants (including CO, NOx, HC) in the process of bus parking by using MOVES2014a model. It is found that among the three emissions, NOx emission is the largest in the process of bus parking. With the decrease of speed, the emission factors of pollutants increase continuously, especially in the idle stage, the emission of bus exhaust reaches the maximum. Under three operating conditions, idle condition has the greatest impact on bus exhaust emission, acceleration condition next, and deceleration condition least.
