为探究多车道高速公路互通立交合流区车辆速度驾驶行为特性，为合流区安全设计提供现实依据，文中选择沪宁多车道高速公路互通立交（群）作为远场观测试验实体工程，采用 MC5600型气压管式车辆分型统计与测速系统采集现场数据及 SPSS Statistics软件处理数据信息。试验表明，多车道高速公路合流区客车、货车速度与出现频率之间可采用正态分布曲线拟合。双车道匝道端部客车平均速度为60～70 km/h，运行速度（v85）为80～90 km/h；双车道匝道端部货车平均速度为60～65 km/h，运行速度（v85）为65～75 km/h；单车道匝道端部货车平均速度为50～60 km/h，运行速度（v85）为60～70 km/h。

In order to explore and research the characteristic of vehicles'speed driving behavior in a multi-lane freeway interchange diverging area,and provide realistic basis for safety design of diverging area,this paper choosed Shanghai-Nanjing multi-lane freeway interchange (groups)as a field observa-tion engineering,and used MC5600 vehicle type pneumatic tube system statistics and field velocity da-ta and SPSS Statistics software processing data.Tests showed that:the relationship between the fre-quency and the velocity of cars and trucks is the normal distribution.Two-lane ramp terminal average speed of cars is 60~70 km/h,and the operating speed (V85 )of cars is 80~90 km/h;Two-lane ramp terminal average speed of trucks is 60~65 km/h,and the operating speed (V85 )of trucks is 65~75 km/h;the single lane ramp terminal average speed of trucks is 50~60 km/h,and the operating speed (V85 )of trucks is 60~70 km/h.
