| 摘 要： | 为研究不同的客货分离改造方案的适用环境，为中国高速公路的客货分离改造提供依据和指导，提出以延误、事故率、改造费用等指标构成的指标体系，采用主成分分析法对该指标体系进行降维，得出客货分离改造方案的选择和评价方法，并通过序列总和理论对当前主流的各种综合评价方法的有效性进行验证.试验结果表明：采用PCA法对客货分离改造方案进行综合评价的有效性优于其他主流的综合评价方法.

| Abstract: | To study the condition of different reforming plans for separating trucks from passenger vehicles and provide guidance for reforming, an index system was proposed in this paper including the indexes of delay, times of changing lanes, coefficient of speed variance etc. The principle component analysis was used to simplify this index system and a selection and evaluation method for separating trucks and passenger vehicles was provided. Then, the effectiveness of this method was testified by applying the theory of serial number summation. The result shows that this method is superior to other current methods in the literature. |
