【摘要】：随着西安市机动车保有量的爆发式增长,机动车尾气污染已经成为大气污染的主要污染源。通过法规限制和改进单车性能来减少尾气排放成本较大,效率较低,从城市交通运行的角度来研究机动车尾气排放成为新趋势。对比现有的机动车尾气排放量化模型,本文选择美国环保署开发的最新模型MOVES(Motor Vehicle Emission Simulator)来研究西安市机动车尾气排放。在对MOVES模型的结构和原理进行分析后,设置模拟场景,采用控制变量法,得到中观层次上影响机动车尾气排放因子的敏感性参数。在此基础上,输入西安市本地参数,模拟2014年11月西安市晚高峰期间三环内小轿车、轻型客车以及轻型货车的CO、NOx以及THC排放因子,并结合不同标准下北京市各车型排放因子,对模拟的排放因子进行验证、分析和评价。最后,提出了机动车尾气排放量化模型和交通仿真模型的组合。本次研究提炼了MOVES运行的主要模块以及模块之间数据交换的关系,为今后我国自主开发机动车尾气量化模型提供依据;分析了MOVES模型中观层次敏感性因子,为西安市机动车尾气排放因子模拟提供依据,从交通运行的角度研究影响排放的因素,为节能减排提供更高效的途径;使用MOVES对西安市高峰期尾气排放进行模拟、评价和分析,为制定新的尾气排放控制策略提供参考依据;提出交通仿真模型与MOVES模型中观层次和微观层次上的结合,为交通环境影响评价提供新方法。
[Abstract]:With the explosive growth of the motor vehicle ownership in Xi'an, the vehicle exhaust pollution has become the main source of air pollution. Through the regulation and improvement of the performance of the single vehicle to reduce the cost of the exhaust emission and the low efficiency, it is a new trend to study the exhaust emission of the motor vehicle from the point of view of urban traffic operation. The model of vehicle exhaust emission quantized, this paper selects the latest model MOVES (Motor Vehicle Emission Simulator) developed by the United States Environmental Protection Agency (EPA) to study the emission of vehicle exhaust in Xi'an. After analyzing the structure and principle of the MOVES model, the simulation scene is set up and the control variable method is used to get the influence of the vehicle exhaust emission at the middle level. On this basis, the local parameters of Xi'an city are input to simulate the CO, NOx and THC emission factors of the three ring cars, light buses and light trucks during the late peak of Xi'an in November 2014, and the simulation emission factors are verified, analyzed and evaluated in accordance with the emission factors of various models under different standards in Beijing. After that, the combination of vehicle exhaust emission quantification model and traffic simulation model is put forward. The main module of MOVES operation and the relation of data exchange between modules are refined. This study provides the basis for the independent development of vehicle tail gas quantizing model in our country in the future, and analyzes the mid level sensitivity factor of the MOVES model, which is a maneuver for Xi'an city. The vehicle exhaust emission factor simulation provides a basis for the study of the factors affecting the emission from the point of view of the traffic operation, providing a more efficient way for energy saving and emission reduction. Using MOVES to simulate, evaluate and analyze the emission of the tail gas in Xi'an, provide a reference for the formulation of the new exhaust emission control strategy, and put forward the traffic simulation model and the MOVES model. The combination of meso and micro level provides a new method for traffic environmental impact assessment.
