Smart Emergency Traffic Light System Using IoT

Created using ChatSlide

Explore an innovative IoT Traffic Light System aimed at reducing emergency response delays through a simulated solution on Contiki-OS. The system architecture enables ambulance requests that adjust traffic lights using sensor nodes. The Cooja simulation demonstrates network setup with Sky motes, enabling signal pre-emption for emergencies. Addressed STRIDE security threats include spoofing, GPS tampering, and Denial of Service, with countermeasures like cryptographic authentication and...
