【摘要】 本文系统研究了道路立体交叉的类型，从不同角度对立交类型进行了划分，在详细论述立交交通量预测模型的基础上，针对四阶段预测法中适合立交特点的主要数学模型做了深入研究，建立了道路立交各基本组成部分通行能力的数学模型，并按照立交的性质及人们对立交的要求，对立交服务水平进了研究，确立了道路立交的服务水平标准，提出了道路立交交通适应性指标，建立了道路立交适应性指标体系，并由多人层次分析法确定了各指标的相对权重。本文通过对立交通行能力的研究，提出了合理的立交交通适应性指标和方案评价模式，实例表明方法正确可行，可为工程应用参考。更多还原

【Abstract】 In this paper, different overpass type has been researched. On the basis of forecast model of traffic volume discussing, the mathematic model for the basic parts of road overpass was built up through the research on main mathematical model which suit for overpass in four-stage forecast method. According to the properties and the requirements of the user, by working on the service level, the standard of service level has been defined. The adaptability index of traffic for road overpass was put forward and an adaptability index of traffic system was established. The relative weight of the indexes is determined by multi-person analytic hierarchy process(AHP). The research on traffic capacity of the overpass and the traffic adaptability index indicating the method in this paper are suitable for engineering application by the example in the paper and the method has potentially applied valuation to practical engineering.更多还原
