Abstract
This study examined spatial pattern of petrol service station using nearest neighbor analysis, the inventory of service stations in terms of marketing official rank and mapping of petrol service stations with a view to providing a framework for the safety of citizen from fire hazards and to protect the immediate environment from fire menace. The data used for this research work was obtained from both primary and secondary data. Primary data included the coordinate point of both the petrol service stations and fire service stations using Global Positioning System (GPS) receiver. Secondary data included land use map of the study area, Administrative Map of Ado–Odo Ota and the list of petrol service station. The data were analyzed using geographic information techniques. From the data survey carried out, the result of the analysis showed that Ado- Odo Ota has one hundred and thirty-four (134) petrol service stations and one fire service station and most of these petrol service stations were located along the major road that passes through the centre of Atan Ota, Iyana Ota, Onipanu Ota, Ojuore Junction, Lagos - Abeokuta highway. The nearest neighbor analysis (NNA) for the spatial pattern of petrol service stations in each region revealed three major spatial distributions. The spatial pattern in Iju to Iyana and Iyana to Ojuore showed dispersed pattern, Abeokuta highway showed random pattern, while Sango Ota showed clustered pattern.
