Abstract: The paper analyzes some transit measure of urban roads’
intersection including balusters，overbridges，signal equipments，tunnels and crossroads with AHP along with some related targets. Ensuring about the security of road transit, at the same time, the paper focuses on transit
capacity as well as factors such as enforcement cost，compatibility with circumstances and urban landscape, and selects casualty reduce，economic loss minimum, urban landscape, enforcement cost and transit capacity as indices on the evaluation. AHP is introduced to set up judge matrixes， calculate the eigenvectors，and check up consistency by latent roots. The results are accepted only when consistency check are fulfilled. In the end, the paper gives a comprehensive analysis and evaluation of usual transit measure of urban roads’ intersection, and then provides a choice of schemes for the reference of related department.

Key words: intersection, target, comprehensive evaluation, AHP

摘要： 通过对城市道路交叉口的守护栏杆、人行天桥、信号设备、地下通道、立交桥等5种通行措施进行分析，在实现道路通行安全性的同时，兼顾车流通行能力，此外还考虑了系统的实施费用、与周边环境的协调、城市景观等因素，从而选择了减少伤亡人数、减少经济损失、城市景观、实施费用和车流通行能力等五个影响道路交叉口通行措施评价的指标，运用层次分析法(AHP)，建立判断矩阵并计算特征向量，并通过计算判断矩阵的最大特征根来检验判断矩阵的一致性.在层次单排序判断矩阵与层次总排序判断矩阵的一致性检验均符合要求后，方案总排序的结果才可以接受.最后，对方案总排序的结果进行了综合分析评价，并得出了可供相关部门参考的评价结果.
