Spatial analysis of transportation infrastructure distribution in Adamawa State, Nigeria: A location quotient perspective

Abstract

Transportation constitutes one of the pivotal systems crucial to the advancement of so-cioeconomic conditions. However, numerous communities, particularly in Nigeria, face a multitude of transportation challenges. The primary objective of this study is to examine the spatial arrangement of transportation facilities in Adamawa State, Nigeria, with the intention of identifying spatial-related challenges confronting the transportation sector and the socioeconomic development of the state. During the period spanning 2018 to 2019, an investigation into the spatial distribution pattern of transport facilities within the state was conducted. To gather data pertaining to the geographical concentration and developmental trajectory of the transportation system in the state, the ArcGIS 10.5 Length Calculation Module, Google Earth Pro, and questionnaire administration were employed. Data were subjected to inferential statistical analysis, results were tabulated, and maps were generated. The findings unveiled three distinct modes of transit, namely road, water, and air, with roads emerging as the most prominent option. Furthermore, the state exhibited a higher prevalence of paved (engineered but untarred) roads compared to tarred roads. Moreover, an analysis of the spatial pattern encompassing the state’s population and road network revealed that the length and density of tarred roads were greater in less populated Local Government Areas as opposed to the more populated ones. Ultimately, the road network pattern has yielded negative consequences for the state’s development. In light of these findings, the study puts forth recommendations that emphasize the urgent need to tar the numerous paved roads within the state in order to enhance connectivity with markets and other urban-centric facilities.
