摘要
沈山高速公路(编号G1)是国家高速公路网中由北京出发的七条放射状路线之一,是东北地区公路交通运输的大动脉,由于现状交通量较大,计划对其进行改扩建,为了确定多车道高速公路的适应交通量,必须对影响通行能力的交通量参数,如设计小时时位、车辆折算系数、通行能力等相关内容进行准确把握,提出更加符合现状交通组成特性、交通分布特点以及车辆状况等相关指标值。主要针对单车道通行能力值进行研究,分析其与车道数的关系,为沈山高速改扩建技术标准选取提供理论依据。
Shenshan Expressway （ No. G1 ） is one of seven radial ways from Beijing in national expressway network, which is a main artery in highway traffic transportation in northeast China. Due to the large traffic volume at present, we plan to perform reorganization and expansion. In order to let the multilane expressway be adapted to the traffic volume, we must know the parameters of traffic volume influencing the traffic capacity correctly like design chroneme of hour, vehicle convert coefficient, traffic capacity and so on, so as to put forward relevant index values that more conform to traffic composition characteristics at present, traffic distribution features and vehicle status and so on. The traffic capacity value of single lane is mainly studied, and the relationship between the value and number of lane is analyzed, thus providing theoretical basis for selection of technical standard of reorganization and expansion of Shenshan Expressway.
