基于信息地理学的ETC移动空间时空变化特征——以中国台湾为例

Spatial-temporal Variation Characteristics of ETC Movement Space Based on Information Geography:A Case Study of Taiwan,China

随着信息地理学原理的发展和高速公路电子自动收费系统的广泛使用,运用信息地理学分析高速公路数据成为研究移动空间和信息地理学的重要方向。基于2015—2022年中国台湾岛高速公路数据采用时间分异特征、空间自相关分析等信息转换方法解释其在人文世界中的时空特征,结果显示:1)时间上,“双流”移动空间具有普遍规律并能在特殊性情况下进行自我修复,时间尺度越小,出行规律越明显,各时间尺度下所形成规律受人文和自然世界不同要素影响。2)空间上,“双流”移动空间构成稳定的多核心三梯度圈层结构,具有正相关特征,形成内部联系紧密、外部联系相对稀疏的关联结构。3)形成以新北市、台北市、桃园市、台中市、高雄市为网络核心,台南市、彰化县为次核心,多个县市之间联络线为联系骨架的网络关系。4)根据“双流”移动空间的空间特征可凝练出串联、发散和核心-边缘演化结构。

The use of information geography approaches to analyze highway data has emerged as a key area of research in the study of virtual transportation space and information geography.The reason is because the thorough development of the principles of information geography and the widespread adoption of highway electronic toll collection systems.The highway data of Taiwan Island during 2015—2022,has used to reflect the spatial-temporal architecture in the human world by adopting information conversion methods such as time differentiation and spatial auto-correlation for the information expression.The findings indicate that,1)from the time perspective,the logistical flow and mobile space of a vehicle have a universal rule and may self-repair in the specific scenario.With a smaller time scale,the more apparent travel law,the traffic flow and logistics travel patterns at various time scales are influenced by different factors in the human and natural worlds.2)From the spatial perspective,logistics and traffic flow create a stable three-gradient circle distribution structure with multiple cores,exhibiting significant spatial positive correlation characteristics.The transportation network has gradually created an association structure with close internal connections and sparse external connections.3)The spatial formation of the transportation system,with New Taipei City,Taoyuan City,Kaohsiung City,Taichung City,and Taipei City serving as the network's core,Changhua County and Tainan City serving as its sub-core,and the connections between other counties and cities serving as the network's connecting skeleton.4)Based on the spatial properties of the vehicular and logistics transportation network,the tandem evolution structure,core-edge evolution structure,and dispersion evolution structure may all be compressed.
