Road Condition Monitoring of Major and Minor Route in Part of Ibadan Metropolis Using Geo-spatial Approach

Abstract

Major and minor road conditions of part of Ibadan metropolis was assessed to analyze the effectiveness and efficiency of the road network system. The major objectives of the study are to locate and identify the road networks within the study area, evaluate the road conditions such as an area with defects such as potholes and crack, evaluate the features that observe and did not observe the right of way using geospatial approach. Single-frequency Hi-target differential global positioning system (DGPS), a steel tape was used for field observations and measurements. Google earth satellite imagery was used to determine the route and spatial location of potholes and cracks within the study area. Generally from the study, it revealed a total number of 81 potholes, 29 cracks and the result from the right of way showed that none of the features observed the specification of right of way thou some of those features exists before converting the road into two lanes for easy passage and flow of vehicle in order to avoid constant traffic congestions. Therefore, proper monitoring should be done by State and local government agency in charge of road construction/maintenance to avoid the improper location of features by an individual, corporate organization etc. along both the major and minor route from time to time and adequate checking on roads.
