Abstract

Urban areas face increasing challenges from traffic congestion and greenhouse gas emissions, often driven by rapid population growth and rising vehicle usage. This demands for significant investigation and analysis to aid improvement and maintenance of road networks. Jabi Bypass, a critical urban route in Abuja, Nigeria, exemplifies these issues due to its high traffic volumes and strategic location. Leading to excessive waiting times and high carbon emissions. To address these challenges, this study employs a simulation-based approach using Simulation of Urban Mobility (SUMO), to analyse traffic patterns and evaluate potential mitigation strategies. Through detailed analysis and scenario-based interventions, including lane expansion and roundabout design, this study demonstrates how targeted infrastructure improvements can lead to a distinct reduction in waiting time, travel delay and Greenhouse gas emissions. The proposed framework can serve as a model for other rapidly growing cities seeking sustainable and cost-effective solutions to urban mobility challenges.
