基于层次分析法的成都双流机场T2航站楼外部区域交通标志有效性研究

Effectiveness Research of Traffic Signs at the Exterior Zone of Chengdu Shuangliu Airport Terminal 2 Based on Analytic Hierarchy Process(AHP)

综合交通枢纽外部区域交通标志的设计与设置将影响驾驶员对路径的选择,从而影响枢纽的运营效率。本文基于层次分析法(AHP),对成都双流机场T2航站楼外部区域交通标志的有效性进行分析。通过研究发现,影响T2航站楼外部区域的交通标志有效性的最主要因素是标志信息准确性、标志连贯程度、标志设置和驾驶员遵从标志指示的服从度。T2航站楼外部区域的标志信息准确性和标志设置的问题较突出,本文提出了相应的改进措施。

Designing and setting traffic signs at the exterior zones of a comprehensive transportation junction will affect the path＇s choice, and the operating efficiency of the junction. In this paper, based on the analytic hierarchy process（AHP）, the effectiveness of traffic signs in the exterior zone of Chengdu Shuangliu airport terminal 2 was analyzed. Study found that the most important factors affecting the traffic sign effectiveness at this zone were information accuracy, coherent degree, sign setting and compliance degree that driver followed the sign indicates. The problems of sign information accuracy and sign setting were outstanding in the zone. Then, some corresponding improvement measures were put forward.
