Background of the study
Urban traffic congestion and road safety remain persistent challenges in many cities, including Minna LGA. Traditional traffic light systems operate on fixed timers, often resulting in inefficient traffic flow, increased congestion, and a higher likelihood of accidents. The emergence of IoT-based smart intelligent traffic light systems offers an innovative solution to these issues. These systems integrate real-time data from sensors, cameras, and GPS devices to dynamically adjust signal timings based on current traffic conditions (Babatunde, 2023). By continuously monitoring vehicle density, speed, and flow, the system can optimize signal phases to reduce waiting times and improve road safety. Advanced algorithms analyze real-time data to predict traffic patterns and adjust signals accordingly, thereby reducing congestion and minimizing emissions from idling vehicles (Ibrahim, 2024). The smart traffic light system not only enhances operational efficiency but also contributes to sustainable urban development by lowering carbon emissions and improving fuel efficiency. Moreover, the system's integration with emergency response protocols can prioritize traffic flow for ambulances and fire trucks, ensuring faster response times during emergencies. Despite the promising potential of these systems, challenges such as high implementation costs, data integration issues, and cybersecurity vulnerabilities pose significant obstacles to widespread adoption in Minna LGA. This study aims to evaluate the performance of IoT-based intelligent traffic light systems, identify the key challenges in their deployment, and propose strategies to overcome these barriers, thereby paving the way for safer and more efficient urban traffic management (Babatunde, 2023; Ibrahim, 2024).
Statement of the problem
The conventional traffic light system in Minna LGA relies on pre-set timing sequences that do not account for real-time traffic variations. This rigidity leads to inefficient traffic management, resulting in prolonged waiting times, increased congestion, and heightened risks of road accidents. Traditional systems are incapable of adapting to unexpected changes such as traffic surges or road blockages, which exacerbates urban mobility issues. Although IoT-based smart traffic light systems have the potential to mitigate these challenges through dynamic signal adjustments, their implementation is hindered by several factors. High installation and maintenance costs, difficulties in integrating data from various sensors, and cybersecurity risks are significant barriers. Furthermore, a lack of technical expertise among local traffic management authorities complicates the deployment and operation of these advanced systems. The gap between the potential benefits of real-time adaptive traffic control and the limitations of existing infrastructure contributes to ongoing urban traffic inefficiencies and environmental concerns. This study seeks to examine the core challenges in deploying IoT-based traffic light systems in Minna LGA and to evaluate their effectiveness in improving traffic flow and road safety. By addressing these issues, the research aims to develop recommendations that will facilitate the integration of smart traffic technologies into the existing urban framework, thereby enhancing overall transportation efficiency and safety (Babatunde, 2023; Ibrahim, 2024).
