机动车尾气扩散模型研究进展

机动车尾气扩散模型作为一种重要的工具被用于评估城市空气质量、为污染控制战略以及交通规划决策制定提供支持。对国内外机动车尾气扩散模式进行了回顾,结合各种模式的特征,将其分为综合扩散模式、开阔道路线源扩散模式、交叉口道路扩散模式以及街道峡谷扩散模式,分别对模式的优缺点以及其适用性进行了分析,针对我国道路交通特征,提出了模型本土化所需解决的问题和未来的研究趋势。

Research progress of vehicle exhaust diffusion model

Vehicle exhaust diffusion model plays an important role in urban air quality evaluation and policy-making for pollution control and transport planning. This paper presents a review of domestic and international vehicle exhaust diffusion models based on their characteristics, including comprehensive diffusion models, open road line source diffusion models, intersection diffusion models, and street canyon diffusion models. The advantages, disadvantages, and application scope of each model are also introduced. Meanwhile, the localization and developing tendency of the vehicle exhaust diffusion models based on the traffic characteristics in China are discussed.
