Tracing and controlling vehicles emissions present a great challenge in reducing air pollution and improving air quality in Beijing. On-road emissions (CO and NOx) and fuel consumption (FC) characteristics of tourist-oriented heavy duty diesel vehicles were analyzed based on 63,226 records of instantaneous data obtained in Beijing using PEMS. The results revealed that CO and NOx emission factors and FC dropped from 2.87 g/km, 10.30 g/km, and 164.86 g/km to 2.44 g/km, 9.45 g/km, and 149.79 g/km respectively, when eight stop-and-go actions were eliminated. These reductions indicated that each stop contributes 1.86% of CO, 1.03% of NOx, and 1.14% of FC respectively to the total emission and FC of a test run. Furthermore, CO emission rate was highest at the moderate speed, while NOx emission rate and FC rate grows with the increase of average speed. These findings provided a base reference to the accurate estimation of the emissions and FC of diesel vehicles in Beijing.
