Minimum green time is dependent on which factors?

Minimum green time is influenced significantly by the location of the detector. The detector is responsible for sensing the presence of vehicles at the intersection, and its placement can affect how effectively it gathers data about traffic demand. When the detector is positioned correctly, it can accurately assess the volume and types of vehicles waiting to cross the intersection, allowing for an appropriate adjustment of the minimum green time to accommodate the traffic flow.

The efficiency of the traffic signal depends on how well it responds to the detected traffic, making the detector's location critical in determining how long the green phase should last to ensure safe and efficient movement of vehicles. This is particularly important in areas with varying traffic patterns, as an optimally located detector provides real-time data that helps minimize unnecessary delays while maintaining safety.

Considering other factors, while severity of traffic, time of day, and type of vehicles can all play a role in traffic signal timing, the immediate and direct impact on minimum green time is most closely tied to the effective functionality and positioning of the detector.
