Abstract: ABSTRACT CONTEXT-AWARE ROAD-RISK ADAPTIVE ACOUSTIC HAZARD WARNING SYSTEM FOR DISTRACTED PEDESTRIANS An on-device pedestrian hazard warning system for a mobile device includes an IMU (110) generating motion data, an activity-recognition module (112) determining a walking state, and a phone-interaction module (114) determining an active-use state. A gating module (140) enables an acoustic sensing pipeline including a MEMS microphone (130), an audio embedding model (160), and a hazard classifier (162) when both states are satisfied. A GPS receiver (120) acquires a current geographic position on demand, a road-network feature extraction (150) extracts road-network features, and a road-risk scoring module (152) computes a numeric road-risk score. An adaptive threshold controller (170) sets a decision threshold applied by the hazard classifier (162) in an inverse relationship to the road-risk score. An alert module (180) generates, when a hazard probability exceeds the decision threshold, a synchronized notification via a display (182), a speaker (186), and a haptic actuator (184). (Fig. 1)
