摘要
在公路可行性研究或项目评估时,同一通道内高速公路与平行辅路交通量分担比例在交通量预测中非常重要,以交通运输的基本机理和追求的目标为分析的出发点,系统的分析了交通运输行为主体和公路属性的各方面对该比例的影响,包括地区的经济水平、不同车型的差异性、高速公路与平行辅路的里程差、等级和路况的对比、通道的交通饱和程度、收费水平等因素,这些因素的分析对实践中该比例的确定具有较强的指导意义.
It is very important of share ratio of freeway and other parallel highway in the same transportation corridor for the traffic forecast. This paper has analyzed the basic mechanism, its pursued goal and the action object. The highway properties have also been discussed, including the economic level, the vehicle difference, the length difference between freeway and parallel highway, the grade difference, the traffic flow level, the traffic fee and so on. The factors analysis is very directive to define the ratio in practice.
