Providing An Intelligent Traffic Signal

Disclosed is a method and system for providing an intelligent traffic signal. The intelligent traffic signal is used to activate green arrows based on vehicle turn signals.

The system includes a camera positioned at the center of a road or on a traffic light pole to detect vehicle turn signals, whether the vehicles in traffic are moving straight or turning.

The Figure illustrates a method flow for providing an intelligent traffic signal.

Figure

As illustrated in the Figure, the method and system enables a motion sensor to determine whether any vehicle in a left lane is successfully taking a left turn or not. If the vehicle is taking a left turn, the system detects a predetermined number of vehicles queued in the traffic before switching the traffic light from red to green. Subsequently, the system identifies whether any vehicle in the predetermined number of vehicles have activated the left turn signal and enables the green arrow by blocking the oncoming vehicles from continuing straight. Conversely, if the vehicle is in the left lane not taking

a left turn, the system activates a left turn green arrow for a predefined number of seconds and further switches to a red light. Further, if the camera does not detect any left turn signal from the predetermined number of vehicles, the system does not enable the green arrow and allows the traffic in the oncoming lane to continue straight without any unnecessary dela...
