基于POI数据的天津市汽车充电站布局优化

Layout Optimization of Tianjin Automobile Charging Station Based on POI Data

针对城市充电站布局不合理、绿色能源车充电困难的问题,利用Python语言,通过高德API获取天津市重要场所热点数据,基于ArcGIS核密度分析、缓冲区分析等方法,研究天津市汽车充电站的均衡性、可达性、配建率等。研究发现,天津市汽车充电站布局较为均衡,天津市核心区域已实现汽车充电站的全覆盖;5 km服务半径时,远郊6区相对覆盖率较低,其中宝坻区和蓟州区覆盖率最低,未超过50%;3 km服务半径时,环城4区覆盖率均未达到90%;远郊6区相对覆盖率除武清区为50.43%,其余均未达到50%。停车场充电站的配建率仅为3.41%。因此,天津市应加强汽车充电站的建设,尤其是城市周边区域,应根据区域热点需求分析,扩大汽车充电站建设,以满足广大市民的汽车充电需求。

The layout of urban charging stations is unreasonable,and it is difficult to charge green energy vehicles.Based on the above problems,the equalization,accessibility,allocation and construction rate of Tianjin Automobile Charging Station are studied.Firstly,the hot data of important places,charging stations and parking lots are obtained in Tianjin through Gaode API,then ArcGIS kernel density analysis,buffer analysis and other methods are used to study.The study found that the layout of automobile charging stations in Tianjin is relatively balanced,and the core area of Tianjin has achieved full coverage of automobile charging stations.When the service radius is 5 km,the relative coverage rate of the six outer suburbs is relatively low,of which Baodi District and Jizhou District have the lowest coverage rate,not exceeding 50%.When the service radius is 3 km,the coverage rate of the four districts around the city does not reach 90%,and the relative coverage rate of the six districts in the outer suburbs,except Wuqing District,is 50.43%,does not reach 50%.The allocation rate of charging stations in the parking lot is only 3.41%.Therefore,Tianjin should strengthen the construction of automobile charging stations,especially in the surrounding areas of the city.The construction of automobile charging stations should be expanded according to the regional hot spot demand analysis to meet the automobile charging needs of the general public.
