中文摘要：

以城市轨道交通示意图为对象,利用AHP方法构建了一个注记质量评价模型。在考虑可辨阈限、注记-要素压盖度、优先级、注记-要素关联性4个独立指标的基础上,补充了单位面积注记量和偏移量两个修正指标。选取上海、伦敦、莫斯科、米兰和圣保罗5个城市的轨道交通示意图进行实例验证,结果显示两个修正指标的提出具有合理性,可为注记配置的自动化提供基本参考。

英文摘要：

A quality evaluation model is given out for automatic label placement concentrating on urban rail transit schematic（URTS） maps with analytic hierarchy process（AHP） method.Besides independent elements of legibility threshold,label-feature overlap,position optimal level and label-feature association,we propose two compensatory indicators that related to the number of labels per unit and distortion level for the comparison of label quality among different URTS maps.The rail transit schematic maps of Shanghai,London,Moscow,Milan,Sao Paulo are presented as example verification.The result shows that the two compensatory indicators are reasonable.
