JS837: SmartCross - Steps That Trigger Safety

Thessmitra Suresh SJKT Sg Renggam

SmartCross is an intelligent, sensor-driven pedestrian safety system designed to prevent traffic accidents and protect vulnerable road users, particularly students and pedestrians crossing in low-visibility or nighttime conditions.

The system utilizes a dual-sensor architecture, combining motion sensors and pressure sensors embedded at the crosswalk. By cross-referencing movement and weight data, SmartCross employs an advanced filtering mechanism to ensure that the system is triggered exclusively by human presence, preventing false alarms caused by animals or debris.

Upon detecting a pedestrian entering the zebra crossing, the system seamlessly coordinates a multi-stage safety protocol:

  • Signal Preemption: It automatically triggers the traffic light to turn red, legally halting oncoming traffic.
  • Visual Alert: It simultaneously activates high-intensity flashing LED lights directed toward approaching vehicles to maximize driver awareness.

By bridge-linking automated sensing with active traffic signaling, SmartCross provides a robust, reliable, and fail-safe environment for pedestrians, significantly reducing nighttime crosswalk hazards and enhancing urban road safety.
