Abstract

Abstract Cities serve as hubs for various activities that necessitate comprehensive transportation connectivity. This study examines the decadal urban agglomeration patterns from 2001 to 2020 and critically assesses the relationship between freeway developments, industrial relocation, and population density in the DFW (Dallas Fort Worth) metropolitan area. Landsat satellite imageries, US census, and open-source GIS datasets have been utilized in the study. The Maximum Likelihood Classification (MLC) algorithm helped generate the vector database, using which Land Use/Land Cover (LULC) variations were assessed. The calculated overall accuracies of the classified images for 2001, 2011, and 2020 were 93.12%, 91.87%, and 93.12%, respectively. Eventually, buffer generation techniques and summary statistics helped detect potential boom hotspots. Our results indicate that the highway advancement project lures industries, leading to population migration. The LULC variations suggest that the increase in highway infrastructure resulted in a surge in built-up and a decrease in open spaces in District-3 of DFW. From our study, we find that 79.16% of old industries are located near old freeways, while 78.84% of new industries are located near new freeways. Further, our industrial area to road area comparison clearly shows that industrial relocation was driven by transportation advancements over time. Our results also confirm that this relocation of industries fostered a massive population influx during the following decades.

交通走廊推进对集聚和产业转移的影响——以美国达拉斯沃斯堡为例
城市是各种活动的枢纽,需要全面的交通连接。本研究考察了2001年至2020年的城市群年代际格局,并批判性地评估了DFW(达拉斯沃斯堡)大都市区高速公路发展、工业搬迁和人口密度之间的关系。研究中使用了陆地卫星图像、美国人口普查和开源GIS数据集。最大似然分类(MLC)算法帮助生成矢量数据库,使用该数据库评估土地利用/土地覆盖(LULC)变化。计算得到2001年、2011年和2020年分类图像的总体准确率分别为93.12%、91.87%和93.12%。最终,缓冲区生成技术和汇总统计帮助发现了潜在的繁荣热点。研究结果表明,高速公路推进工程对产业的吸引,导致了人口的迁移。LULC的变化表明,公路基础设施的增加导致了DFW第3区建筑面积的激增和开放空间的减少。从我们的研究中,我们发现79.16%的老工业位于旧高速公路附近,而78.84%的新工业位于新高速公路附近。此外,我们的工业区与道路面积的比较清楚地表明,随着时间的推移,工业迁移是由交通进步驱动的。我们的研究结果还证实,在接下来的几十年里,这种产业的迁移促进了大量人口的涌入。
