In areas surrounding school zones, incidents of vehicles failing to slow down or running red lights pose a significant threat to pedestrians, especially young students. "Guardian of Safety" is an intelligent pedestrian protection system designed to enhance crosswalk safety, integrating three core functions: visual alerts, physical barriers, and automatic control to create a dynamic and proactive safety mechanism. The system features a pneumatic lift mechanism synchronized with traffic signals; during a red light, a physical barrier rises from the center of the speed bump, accompanied by a red light warning, effectively preventing vehicles from encroaching on pedestrian zones and increasing drivers' awareness and violation costs. Emphasizing modular deployment and seamless urban integration, it is particularly suited for high-foot-traffic areas such as schools and hospitals. With all-weather operation and low maintenance requirements, "Urban Safety Patrol" offers a practical and forward-thinking solution to urban traffic safety challenges.
