汽車尾氣對大氣的污染已經成為主要公害，直接危害人類的健康，也破壞著自然界的生態平衡，引起了各國的重視。高速公路收費站尾氣污染的評價對工程建設和已有收費站的環境評價有著重要的意義，設計一個可視化的評價系統對高速公路收費站的工程建設及其已有收費站的環境評價有較大的實用價值。
本文以高速公路收費站為研究對象，討論了CO、NOx、VOC排放量的計算方法。首先分析了車輛尾氣污染評價方法的國內外研究現狀，就目前應用較為廣泛的美國和歐洲的幾種模型做了簡要介紹和對比。參考COPERTⅢ模型中的車輛分類方法和計算公式，得到小客車、大客車、輕型貨車、重型貨車四種類型車輛在不同行駛速度下的CO、NOx、VOC排放量計算公式。運用Visual Studio 2010平臺開發出一個可視化的評價系統，計算出建立收費站前與建立收費站后的排放數據，并將兩項數據進行對比，得到高速公路收費站尾氣污染評價數據。本文還以京珠高速珠海收費站為例進行了尾氣污染評價。

ABSTRACT
Automobile exhaust pollution of the atmosphere has become a major nuisance, endanger human health directly, but also destroy the ecological balance of nature, has attracted national attention. Exhaust pollution, highway toll station construction and eva luation of toll station of the environmental assessment has been of great significance to design a visual eva luation system for highway toll station construction and the environmental assessment has been a toll station Great practical value.
In this paper, highway toll station for the study, discussed the CO, NOx, VOC emissions calculation. First analyzes the eva luation method of vehicle exhaust pollution research status at home and abroad, is widely used on the current model of the United States and Europe COPERT MOBILE model gives a brief introduction and comparison. Reference COPERT Ⅲ model vehicle classification methods and formulas, are small passenger cars, buses, light goods vehicles, heavy goods vehicles are four types of vehicles traveling at different speeds of CO, NOx, VOC emissions formula. Platform using Visual Studio 2010 to develop a visual eva luation system, calculated to establish toll booths before and after the establishment of emission data, and compare the two data obtained highway toll station exhaust pollution assessment data. This article also in Zhuhai, Beijing-Zhuhai Expressway toll station as an example to exhaust pollution assessment.
Key words：Exhaust pollution eva luation system Toll Station COPERT Ⅲ CO NOx VOC VS2010
