山地城市道路排放测算研究现状

为测算山地城市在坡弯地形下的排放问题，从面向排放的交通路网量化方法、车辆排放量化方法、以及耦合交通与排放的量化参数三个方面，分析国内外道路排放测算研究现状与趋势，在此基础上，结合山地城市的特殊地形对排放的影响，分析出测算山地城市道路排放的现状与缺陷：排放模型统计粒径开始细化，山地城市缺乏对应模型；缺乏交叉口实际运行状态的运行模式分布模型。

Research Status of Road Emission Measurement and Calculation in Mountain Cities

In order to calculate the emission of mountain cities under sloping terrain, the research status and trend of road emission measurement at home and abroad are analyzed from three aspects: the quantitative method of road network for emission, the quantitative method of vehicle emission and the quantitative parameters of coupling traffic and emission. On this basis, combined with the special terrain of mountain cities, the research status and trend of road emission measurement at home and abroad are analyzed. Based on the analysis of the impact of emissions, the present situation and shortcomings of road emission measurement in mountainous cities are analyzed: the statistical size of emission model is beginning to refine, there is no corresponding model in mountainous cities, and there is no operational mode distribution model for the actual operation status of intersections.
