Perceptions and usability of road impact mitigation measures: a case study of Northern Bypass road project.

Abstract

Flyovers, also known as pedestrian overpasses, are vital components of modern urban infrastructure designed to enhance traffic management, reduce congestion, and improve pedestrian safety. However, there is a limited understanding of the actual utilization and effectiveness of flyovers, particularly in developing countries like Uganda. This study aims to bridge this knowledge gap by investigating the factors influencing flyover usage and its impact on pedestrian safety in Kampala city. The study aimed to generate knowledge on the efficacy of mitigation measures used to reduce the impact of road infrastructural projects in Uganda. The research objectives were focused on determining the use rate of a flyover facility by different categories of road users, assessing the factors determining the decision to use the flyover, and determining the perception of people on the usability of the flyover. The study used exploratory and descriptive designs involving both qualitative and quantitative research methods. The study's findings reveal that flyover usage is significantly influenced by population density and activity levels. Areas with high population density and more activities, such as the Kalerwe flyover, exhibit higher usage rates due to traffic avoidance and time-saving advantages. Time of day and gender play a critical role in determining how pedestrians choose to use flyovers. Morning and evening rush hours witness higher flyover usage. The findings showed that the use of flyovers as road impact mitigation measures is perceived positively by road users. The study also found that the factors determining the decision to use the flyover include convenience, safety, and time-saving. The study recommends that decision-makers in Uganda national roads authority and other road construction companies should provide road frameworks that minimize pedestrian road accidents like construction of flyovers in places where they are likely to be used.
