多模式下不同停车驾驶行为的尾气排放规律研究

Research on Exhaust Emission Rules Under Different Parking Driving Behaviors in Multiple Modes

为研究停车场内不同驾驶行为对尾气排放的影响,经过实地调查和数据处理,获取机动车在停车场范围内速度、加速度等参数。通过机动车在不同的停车位的停车方式和驾驶模式变化,划分为8种不同的驾驶行为。使用MOVES软件计算不同驾驶行为下机动车尾气排放污染物的排放速率。结果表明:相同的驾驶模式下,平行式停车位进行停车时的尾气排放量普遍大于在垂直式停车位进行停车;车位相同的情况下啊驾驶模式为减速尾气排放量相对最低,驾驶模式为多次减速加速直至减速的情况下尾气排放量相对较高。

In order to study the influence of different driving behaviors on exhaust emissions in parking lots,the speed and acceleration parameters of motor vehicles in parking lots were obtained through field investigation and data processing.Through the change of parking mode and driving mode of motor vehicles in different parking Spaces,it is divided into 8 different driving behaviors.The MOVES software is used to calculate the emission rate of vehicle exhaust pollutants under different driving behaviors.The results show that the exhaust emissions of parallel parking Spaces are generally greater than that of vertical parking Spaces under the same driving mode.In the case of the same parking space,the emission of exhaust gas is relatively low when the driving mode is decelerating,and the emission of exhaust gas is relatively high when the driving mode is decelerating and accelerating until decelerating.
