Transit Signal Priority (TSP)

Traffic congestion, poorly allocated signal timings, and frequent accidents are major challenges in urban areas today. A robust Traffic Signal Monitoring System (TMS) is essential for managing urban traffic, particularly in densely populated cities. Modern TMS solutions leverage next-generation technologies such as Information and Communication Technology (ICT) and the Internet of Things (IoT) to address these challenges effectively. Challenges and the Need for Smarter Systems Urban mobility is becoming increasingly difficult to control due to high vehicular density and complex road networks. Emergency vehicles like ambulances and fire brigades face significant delays when navigating through heavy traffic to reach their destinations on time. Existing traffic systems often struggle to manage blockages and congestion at signals or on roads, necessitating the development of centralized and intelligent traffic management solutions.

Bus Signal Priority (BSP) systems are designed to enhance the efficiency and reliability of transit operations by adjusting traffic signal timing to prioritize buses at intersections. This technology minimizes delays, improves travel times, and ensures smoother traffic flow for public transportation. The BSP system works by interrupting standard traffic signal operations at both isolated and coordinated intersections. When a bus equipped with the system approaches, it can either extend the green light on its route or shorten the red light to provide an uninterrupted path. In some cases, the system adjusts the entire signal cycle to ensure minimal disruptions to overall traffic flow. Key Features of Bus Signal Priority Green Band for Buses: Ensures a clear path for buses by creating a green signal along their route. Adaptive Timing Adjustments: Modifies signal timing dynamically to minimize delays for public transit vehicles. Safer Operations: Facilitates smoother traffic interactions,...
