Direct Vehicle-to-Pedestrian (V2P) Safety Communications
Vehicle2Pedestrian establishes a high-reliability direct radio link between moving vehicles and pedestrians' personal smartphones. By computing mutual collision cones every 100 milliseconds over PC5 sidelink, it activates emergency automatic braking and triggers intense phone vibrations before tragedy strikes.

Central Controller: V2P Safety Arbitrator — PC5 / Direct Radio Core
Zonal Control Units & TSN Ring
- Mutual Collision-Cone Calculator
- Smartphone D2D Sidelink Transceiver
- Pedestrian Acoustic / Haptic Alert Trigger
- Zonal Brake-by-Wire Autonomous Interlock
- Low-Power GNSS Differential Correction Pipe
Giving Both Driver and Pedestrian Equal Warning in Critical Blind Spots
Autonomous emergency braking (AEB) systems work only when the vehicle can see the pedestrian; in dense urban alleys or night-time country roads, by the time headlights illuminate the victim, kinetic physics makes stopping impossible. Vehicle2Pedestrian provides dual-ended warnings: the vehicle initiates braking while the pedestrian's phone screams an emergency warning tone, prompting both parties to take evasive action simultaneously.
Core Engineering Areas
- Mutual Collision-Cone Kinematics — Computing velocity vectors and dynamic boundary envelopes every 100 milliseconds to identify if vehicle and pedestrian trajectories will intersect within a 2.5-second horizon.
- Smartphone Audio-Haptic Alerting — Triggering immediate haptic vibration patterns, flashing camera strobe LEDs, and high-frequency acoustic warning tones on the pedestrian's phone even if set to 'Do Not Disturb'.
- Low-Power D2D Beaconing — Using step-counter hardware interrupts and low-power GPS geofences so the phone only broadcasts safety beacons when the user is moving outdoors near roads.
