摘　　要：采用实地监测的方法,对天津市典型区域(中心城区、远郊区)、典型道路(快速路、主干路、次干路、支路、集疏港公路)机动车实际活动水平特征进行调查和统计分析。各道路的车流量和车速小时变化趋势均分别呈现出较明显的"M"型和"W"型特征,与人们日常出行规律相符。中心城区同类型道路车流量高于远郊区,同类型道路车速与远郊区基本相当。不同类型道路车队构成存在较大差异,但小型客车仍为各类型道路主流车型,均占80%以上,远郊区货车比例相对较高。集疏港公路具有显著的"潮汐交通"特点,"客货混行"造成"港城交通矛盾"突出。The real vehicle activity characteristics of typical roads(express roads,artery roads,secondary roads,local roads and port highway)and typical districts(central city and outer suburb)in Tianjin were recorded and analyzed with a method of field investigation.The variation trends of hourly traffic flow and speed of each road showed the characteristics of relatively obvious“M”and“W”curves respectively,which were coincidence with people’s regular daily travel pattern.The traffic volumes of the central city were much higher than that of the same types of roads of the outer suburb,while the speeds were approximately equal.The traffic fleet compositions of different types of roads had great differences,but the light-duty vehicles were still the mainstream of all roads with a proportion of more than 80%,and the proportion of trucks of the outer suburb was higher than that of the central city.In particular,for the port highway,it showed a remarkable feature of“tidal traffic”,and the city-port traffic conflict was outstanding because of the mixed traffic flow of the passenger cars and logistics trucks.
