Abstract

Abstract: Evaluation for the city road traffic safety is a comprehensive subject.It is indispensable to improve the city road traffic safety and make the road traffic work smoothly.By using the method of principal component analysis（PCA），several main safety indexes are selected，and the safety coefficients of several different roads are calculated by the mathematics software.The bigger the value is，the more dangerous the road is.Comparing the result with the existing reference，in which using the method of Fuzzy Comprehensive Evaluation，the result validates the PCA is in availability，which is suitable for evaluating the rationality of transportation planning in a city area，and the PCA owns its advantages in some special occasions.

Key words: city road traffic, traffic safety, principal component analysis

摘要： 城市道路交通安全评价是一个综合性的课题，是改善道路交通安全、实现城市交通安全快捷不可或缺的部分。利用主成分分析的方法，选定几个评价其安全的主要指标，利用数学软件计算得出不同的几条路面的综合安全系数，得分越大表明危险系数越高；然后将所得结果与已有的参考文献中利用模糊综合评价法得出的结果比较，得出主成分法是可行的，而且能利用到实际的测评中来衡量某个城市区域交通规划的合理性，并在一些特定场合有其特有的优越性。
