墨西哥城的快速公交网络Metrobus的引入是为了减少拥堵，提高城市交通效率和减少空气污染排放。2005年6月，首都圈第一条BRT线路开始运营。我们使用差异中的差异技术，使第一个定量评估的政策影响的BRT系统对空气污染排放。考虑的空气污染物是一氧化碳（CO）、氮氧化物（NOx）、小于10 μ m的颗粒物（PM10）和二氧化硫（SO2）。事后分析使用BRT实施前后空气质量监测站的真实的现场数据。结果表明，BRT构成了一个有效的环境政策，减少排放的CO，NOx和PM10。
Mexico City's bus rapid transit (BRT) network, Metrobus, was introduced in an attempt to reduce congestion, increase city transport efficiency and cut air polluting emissions. In June 2005, the first BRT line in the metropolitan area began service. We use the differences-in-differences technique to make the first quantitative assessment of the policy impact of a BRT system on air polluting emissions. The air pollutants considered are carbon monoxide (CO), nitrogen oxides (NOx), particulate matter of less than 10 mu m (PM10), and sulfur dioxide (SO2). The ex-post analysis uses real field data from air quality monitoring stations for periods before and after BRT implementation. Results show that BRT constitutes an effective environmental policy, reducing emissions of CO, NOx, and PM10.
