A school bus sensing traffic light changer designed to ensure the safety of students entering or exiting a school bus at an intersection. When a school bus stops at a traffic light, the driver can activate a control panel on the dashboard to send a wireless signal from a signaling device mounted on the bus roof. This signal is received by a sensor on the traffic light, which then interfaces with the traffic signal control panel to change all traffic lights at the intersection to red and crosswalk signals to walk. The control panels are connected through communication wires to facilitate this process. A visual indicator on the sensor confirms the signal reception, ensuring that the lights change accordingly. Once the students have safely crossed, the driver can deactivate the signal, allowing the traffic lights to return to their normal operation.

When a pedestrian moving toward the crosswalk is present, the controller determines whether a pedestrian who halts at an entry of the crosswalk in the vicinity of a border in the crosswalk between a footpath and the crosswalk is present. Based on a result of the determination, the controller determines whether the vehicle 1 is allowed to move slowly and pass the crosswalk or the vehicle 1 is brought to a halt. When a pedestrian moving toward the crosswalk is absent, the controller determines that the vehicle 1 is allowed to move slowly and pass the crosswalk.SELECTED DRAWING: Figure 1
