A GIS APPLICATION FOR THE MANAGEMENT OF ROAD INFRASTRUCTURE MAINTENANCE PLAN A CASE OF SAWULA TOWN, GOFA ZONE

Abstract

Effective road asset management is essential for reducing the economic impact of road deterioration, particularly for municipal roads. It helps extend the lifespan of infrastructure, lowers maintenance costs, and ensures timely repairs. Geographic Information System (GIS) technology plays a vital role in enhancing decision-making, resource allocation, and prioritizing maintenance for local authorities overseeing infrastructure. Sawula town faces significant challenges in managing its 71.55 kilometers of municipal roads due to the absence of a modern asset management system. Nearly 50% of these roads require maintenance, but the current system is inadequate. This study explores the feasibility of implementing a GIS-based asset management system specifically for Sawula's municipal roads (excluding federal and regional roads). The research evaluates existing management practices, identifies key factors affecting road maintenance, and develops a GIS framework through stakeholder interviews, surveys, and visual inspections. The findings reveal that Sawula's road management relies heavily on paper-based documentation, which is confimed by 75% of respondents. Of the 71.55 kilometers of roads, only 3% are paved, while 97% remain unpaved. Condition assessments show that only 21% of roads are in "very good" condition, 24% in "good" condition, 6% in "fair" condition, 32% in "poor" condition, and 13% in "very poor" condition. GIS technology can provide accurate, real-time data on road conditions, improving planning and maintenance prioritization. Key factors contributing to road deterioration include inadequate drainage, water project expansions, and heavy truck traffic, which result in shifting cobblestones and potholes. Recommendations for Sawula include establishing regular maintenance schedules, designing effective drainage systems, and implementing climate-responsive maintenance plans. A centralized database for road data would further enhance analysis and decision making. Overall, the proposed GIS framework is expected to significantly improve the management of Sawula’s municipal roads, offering a cost-effective solution for small towns with limited resources and promoting the sustainability of local infrastructure.
