Abstract
Petrol filling stations (PFSs) are not only prime mover of industrial activities but also anessential support in the movement of humans, goods and services in particular and the entire transportation sector worldwide. It locations as well as compliance to established norms and standards are there vital in sustainable urban planning and environment management. The prime motivation of this study is to evaluate the distribution of filling stations in Egor Local Government Area of Edo State, using GIS. Key objectives were to identify and map PFSs, examine the distributional pattern, investigate extent of compliance to 2km and to recommend measures for effective distributional pattern of petrol filling stations in the study area. Global Positioning Systems (GPS) receiver was used to obtain spatial coordinates of PFSs while GIS was used in data analyses and presentations. Also, Nearest Neighbour Analysis (NNA) was used to assess PFSs distributional pattern. The results showed that there are 32 PFSs with 21 (65.6%) and 11 (34.4%) owned by Independent and Major Marketers respectively and are concentrated in the northern part of the LGA. Clustered pattern was also found with NNA of 0.753 at 99% confidence level. One PFS (IOU) complied with the locational standard within 2km radius while 31 others violated the DPR rules. The study recommended appropriate sanctions on PFSs operators/owners who have violated the DPR rules. Remote sensing, GIS and GPS should be deployed in assessing spatial phenomena as it is capable of supporting policies and in making informed decisions.
