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) _____________________________________________________________________________________________________ *Corresponding author: Email: [email protected]; Ogunyemi et al.; ARJASS, 2(1): 1-11, 2017; Article no.ARJASS.30048 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. Keywords: Nearest neighbor analysis; dispersed; clustered; petrol service station; spatial analysis. 1. INTRODUCTION use of automobiles (Cars etc), generators and other petroleum demanding plants.
