Dynamic Road Segmentation of Part of Bosso Local Government Area, Niger State.

Abstract

Dynamic road segmentation (DRS) data model finds maximum application in GIS Transportation (GIS-T) studies and analysis; serving as a data model that splits linear features into new set of segments wherever its attributes change. Attempt has been made by this research to carry out the Dynamic road segmentation of part of Bosso Local Government Area of Minna using an IKONOS image of 1-m Pan-sharpened spatial resolution and other field survey acquired data. Geometric data was acquired using Handheld GPS receivers while the attribute data was acquired via the social survey approach (administration of questionnaires, direct observations and on-site interviews). A Geo-database was designed and created within the Arc GIS 10.0 version software environment. Analysis and queries were also performed to solve some pertinent issues concerning the route segments and to highlight the closest infrastructural facility in case of emergencies. The result highlighted the present road pavement condition of the considered road segments, adjacent land use, traffic congestion rate, notable crime spots and accident hotspots. It also suggested that the building up of traffic congestion along the Kpakungun round about axis is due to the road width (8m), high traffic volume and the dilapidating state of the road’s pavement.
