| 摘 要： | 通过对深圳市机动车典型路段的车流量、行驶速度的监测调查，发现轿车是深圳车流量最大的，并呈现出了双峰分布，而不同路段总的车流量也呈现双峰分布，出现的时段分别为上午9：00和下午18：00，车辆行驶速度在不同路段和时间段变化显著，市区平均车辆行驶速度约为25km／h．利用林格曼黑度表征尾气的超标状况，发现柴油车超标远远大于汽油车．

| Abstract: | Having monitored and surveyed the traffic flow magnitude and driving speed in the typical road sections,we discovered thar the car's traffic is the biggest flow and presents the split-blip distribution.the total traffic flow magnitude of different road sections also presents the split-blip distribution.Rush hours are respectively 9am and 18pm.The change of vehicles' moving speeds when in different road sections and different time is remarkable.The average speed in the downtown areas is about 25KM/h.Using the Germann blackness to represent exhaust excess condition,we discovered the diesel engines by far exceed the gasoline motorcars in exhaustexcess. |
