摘 要: 为体现客货分离高速公路在通行能力方面的优势,对客车专用高速公路和一般高速公路进行对比分析。从客车专用高速公路的定义及评价标准出发,运用数学分析方法和对比分析方法,分析客车专用高速公路和一般高速公路的设计通行能力,并在此基础上对他们的实际通行能力进行对比分析。研究结果表明:车道数为8车道时,客车专用高速公路的实际通行能力比一般高速公路的实际通行能力提高13%以上;车道数为6车道时,客车专用高速公路的实际通行能力比一般高速公路的实际通行能力提高15%以上;在交通量组成一定的情况下,采用新建1条4车道客车高速公路比现状一般4车道高速公路进行4改8有明显优势。结果表明:修建客车专用高速公路比一般的高速公路更能满足通行能力的要求,说明高速公路客货分离拥有良好的发展前景,为评价客货分离高速公路服务水平及技术指标的选取奠定了理论基础。

Abstract:In order to reflect the advantages of the separation expressway of passenger and freight in the aspect of traffic capacity, this paper compared and analyzed the passenger dedicated expressway and normal expressway. This paper begins with the definition and evaluation criteria of the passenger dedicated expressway, and analyzes the design capacity of the passenger dedicated expressway and normal expressway by using the method of mathematical analysis and comparison. The results show that the actual capacity of the dedicated expressway is more than 13% higher than that of the ordinary expressway when the lane number is eight; when the number of lanes is six, the actual capacity of the dedicated expressway is more than 15% higher than that of the ordinary expressway; In a certain traffic volume situation, comparing with the general four lanes expressway to eight lanes expressway, building a new four dedicated lanes expressway has obvious advantages. Analysis results show that the passenger dedicated expressway is more suitable for the capacity requirements than normal expressway, in other words, expressway separation of passenger and freight has good prospects for development, and provides theoretical basis for evaluation of service level and the selection of the technical indexes of the separation expressway.
