宁波市区道路汽车行驶工况调查研究

Research of Vehicle Driving Cycle on the Road in Ninbo City

利用GPS调查了宁波市不同道路汽车行驶工况,记录了实际道路汽车行驶瞬时速度的大量数据.根据这些调查数据进行了不同道路汽车行驶工况的解析,分别建立起适合宁波市汽车排放污染物测量的一般道路汽车行驶工况、快速道路汽车行驶工况、城区综合道路汽车行驶工况的监测系统.

Driving patterns of automobile are investigated on different roads in Ninbo city, using advanced instruments （GPS）. Large amount of testing data of speed under realistic road condition are obtained.On the basis of these investigation data, analyses of driving cycles are conducted. The typical driving cycles used for in-use vehicle emission factor test are developed, which include the driving cycles for ordinary roads with traffic-light, fast highway without traffic-light, comprehensive urban road, respectively.
