Based on the cruise control limit model,this paper studies the effects of speed humps on the emission of traffic flow system.The simulation results under periodic boundary conditions show that when vehicle density is low,the increase of speed humps leads to a significant increase in carbon dioxide(CO2)and particulate matter(PM)emissions.If the vehicle densi-ty is high enough,the speed humps has little effect on the emissions of the system.Compared with the calculation results ob-tainned in the NaSch model,when the road traffic flow density is low and the number of speed humps is set reasonably,the ad-vantage is that the system has greater traffic flow and driving speed,with less CO2 and PM emissions.
