基于潜能模型的粤港澳大湾区民用机场公路交通网络可达性研究

Research on Accessibility of Highway Traffic Network of Civil Airports in the Guangdong-Hong Kong-Macao Greater Bay Area Based on Potential Model

针对粤港澳大湾区机场布局优化和服务能力评估等问题,依托全省高速公路联网收费数据、国省道调查数据,在深入分析湾区城市间出行特征的基础上,提出了民用机场可达范围与服务人口两项指标,建立了基于潜能模型的机场可达性综合评价方法,运用ArcGIS的空间网络分析模块挖掘了民用机场区域交通可达性的空间特征,并从"6+1"民用机场格局、2035年规划公路网两个因素比较湾区内民用机场可达性的变化情况。研究表明,广州白云机场可达性系数最高,珠海金湾机场可达性系数最低。"6+1"民用机场和2035年规划公路网变化将使湾区民用机场可达范围、服务人口和可达潜能得到有效提升,验证了上述方法的可靠性和适用性。

In view of the optimization of airport layout and evaluation of service capacity in Guangdong-Hong Kong-Macao Greater Bay Area,by analyzing the trip characteristics of bay area cities based on expressway networking toll data,national and provincial highway survey data in the entire Guangdong Province,two indicators,namely,the reachable range and the served population are proposed,a comprehensive evaluation method of accessibility based on potential model is established.The spatial characteristics of regional traffic accessibility of civil airports are deeply excavated by using the spatial network analysis module of ArcGIS.Then,comparing the changes of civil airport accessibility in the bay area from two factors of"6+1"pattern of civil airport and the planned highway network in 2035.The results show that Guangzhou Baiyun Airport has the highest accessibility coefficient and Zhuhai Jinwan Airport has the lowest,and the growth of two factors have brought about the improvement of civil airport accessibility,service population and accessibility potential in the Bay Area of Guangdong,Hong Kong and Macao,which verifies the reliability and applicability of the above method.
