Road network is one of the infrastructures used to transport goods from one area to another within and outside the country. In Tanzania, road networks are categorized into three: trunk roads, regional roads as well as urban roads and feeder roads. The first two (trunk and regional roads) are managed by TANROADS while TARURA manages the later (urban and feeder roads).
The agencies use two different systems to manage maintenance works of roads, with TANROADS using Road Maintenance, Management System and TARURA using District Road Management System.
This research study aimed at developing a model for maintenance priority setting in road maintenance works in TANROADS only, in an attempt to address the shortcomings/challenges facing the current TANROADS system. Employing both qualitative and quantitative research methods, the study data were collected using questionnaires, interviews and literature review. Primary and secondary data was analysed by using Statistics Package for Social Science (SPSS v. 20). These were used to develop the maintenance priority setting model to improve priority setting in the planning stage of roads maintenance.
The study found RMMS to have a problem in prioritization process during road maintenance at planning stage by using road surface condition, maintenance budgets, industrial area, road connectivity (linking) and traffic loading. These have high impact in road during maintenance planning stage. The proposed model assists in planning the road maintenance by following aspects or variables identified. The modified system in priority setting model increases effectiveness of the system and decreases political biasness in road maintenance. The study had limitation on developing model, for further study researcher recommends the model be tested in the TANROADS system as module for priority setting during maintenance planning of road networks. |
