Summary
This study examines road maintenance management in Kano Metropolitan, Nigeria, focusing on the Kano State Road Maintenance Agency (KARMA). The research was motivated by the critical role of road transport in Nigeria’s economy and the persistent deterioration of road networks despite significant financial investments. The authors aimed to identify prevalent road defects, determine contributing factors, assess road user satisfaction with KARMA’s maintenance efforts, and analyze deficiencies in the agency’s defect reporting and documentation systems. The methodology involved a mixed-methods approach comprising questionnaires, interviews, and maintenance report reviews. Data were collected from 25 professionals within KARMA, the Kano State Urban Planning and Development Agency (KNUPDA), and the Ministry of Works, as well as 53 road users. The survey instruments were analyzed using SPSS and the Average Index method, with reliability confirmed via Cronbach’s Alpha coefficients (0.737 for professionals and 0.801 for users). Interviews with eight KARMA staff members provided qualitative insights into operational procedures. The findings identified potholes, patching, utility cut reinstatement, edge cracks, and depression as the most frequent road defects. Professionals attributed these deteriorations primarily to traffic load and volume, structural failures due to poor design and construction, inadequate maintenance policies and standards, poor construction conditions, and insufficient drainage systems. Road user satisfaction was overwhelmingly negative; the overall satisfaction index with KARMA’s performance was 2.48, indicating dissatisfaction. Users were particularly dissatisfied with the quality of defect patching, the speed and efficiency of repairs, accident clean-up times, and the complaint redressal system. Furthermore, the study revealed that KARMA relies on a traditional, manual reporting system where repairs are often delayed pending government funding approval, and there is no prioritization mechanism for urgent defects like potholes. The study concludes that the current maintenance management in Kano Metropolitan is ineffective, characterized by poor infrastructure quality, inadequate policy implementation, and an unsatisfactory reporting system. The authors imply that the reliance on traditional, non-systematic reporting methods contributes to delays and increased road deterioration. The findings suggest a need for improved maintenance standards, better drainage infrastructure, and the adoption of more efficient, possibly technology-driven, reporting and inspection systems to enhance road utility and user satisfaction.
