An Evaluation Method of Airport Accessibility Considering Land-Side and Air-Side Transport System
将机场可达性分为陆侧和空侧两部分，基于中国141个民航机场的陆路交通网络和航班时刻数据分别计算，分析时空分布特征，为机场选址和运营管理提供科学依据。
To measure airport accessibility,this paper divides it into two parts,which are land-side accessibility and air-side accessibility.The former indicator is introduced to evaluate the convenience degree of air travelers to access the airport within the catchment area,and the latter one is to evaluate the level of service airport can provide for air travelers to visit the destinations.This paper takes 141 civil airports in China as our evaluation objects.The land transport network of airport is built on the platform of SAGA GIS,and an aviation spatial-temporal service network is built according to airport flight schedule information.And thus the land-side and air-side accessibility is calculated respectively.The distribution characteristics of airport accessibility is analyzed and compared in the spatial and temporal dimension.The proposed evaluation method encourages the airport planners and operational managers having a deeper understanding about how to locating an airport and assign aviation resources,and meanwhile,it ensures the scientific validity of airport location decisions and operation and management schemes.
