以广东省境内丘陵区、平原区、山区三种地形条件下的粤赣高速、开阳高速、京珠高速公路粤北段等典型高速公路的实地采集数据为基础,统计分析了其交通运行特性,结果显示广东省典型高速公路的交通量在各断面分布稳定,交通量方向分布均匀;各车型组成比例在时间、空间分布上基本稳定,其中小客车和大型货车占据主导地位,且发现车型组成比例的变化会带来交通量大小的变化;小型车速度明显高于大型车速度,道路线形、交通组成及周围环境等都会影响车速,且对不同车型车速的影响情况相似。这些调查结果将为高速公路的交通管理工作提供具有价值的参考资料,为交通问题的解决提供可靠的数据支持,使交通调查分析得到更广泛的应用。
Taking the collected data of Guangdong-Jiangxi Expressway, Kaiyang Expressway and Yuebei Section of the Beijing-Zhuhai Expressway under the three terrain conditions of hilly area, plain area and mountainous area of Guangdong Province, based on the collected data of the typical expressways, the traffic characteristics The results show that the traffic volume of typical expressways in Guangdong Province is stable in all sections and evenly distributed in the direction of traffic volume. The proportion of each model is basically stable in terms of time and space distribution, and the passenger cars and large trucks occupy the leading position. The change of proportion will bring the change of traffic volume. The speed of small vehicle is obviously higher than the speed of large vehicle. The road shape, traffic composition and surrounding environment will affect the speed of vehicle, and the influence on the speed of different vehicles is similar. These findings will provide valuable reference materials for expressway traffic management, provide reliable data support for the traffic problem solving and make the traffic survey analysis be more widely used.
