摘　　要：投影决策方法是一种基于矢量投影原理建立的综合评价方法,通过比较各方案投影值的大小来区分各方案的优劣。利用投影决策方法建立城市轨道交通线网规划评价与决策模型,并通过实例验证,说明该方法较直观、计算简单,能全面分析指标间的相互关系,反映整个因素指标空间的影响,提高轨道交通线网规划评价的合理性。The projection decision-making method is a comprehensive evaluation method which is based on the vector projection principle, and could differentiate the quality of various plans through comparing the size of various plans＇ projection value. The paper suggests that the urban rail transit network evaluation and the decision-making model could be established by using the projection decision-making method. The model is testified that the method is easily to understand and calculate, could fully analyze the relationship between indices, reflect the affection of whole factor index space, and increase the rationality of planning evaluation for urban rail transit network.
