Abstract

Efficient Advancements in intelligent transportation systems increasingly demand multimodal sensing frameworks capable of operating reliably under noisy, unpredictable real-world conditions. This research presents a Smart Car Audio Intelligence framework that leverages Machine Learn- ing (ML) and Reinforcement Learning (RL) to enhance real-time vehicle perception, safety, and situational awareness. Unlike traditional single-modality or static audio models, our approach integrates four specialized submodules - Emergency, Alert, Environmental/Human sounds, and Accident detection models which are each optimized through a combination of Transformer, CLAP, and CRNN architectures, augmented with adaptive RL agents. The ML models achieved strong baseline performance across all categories, with up to 99% accuracy and 0.99 AUC, while the integration of RL (DQN and PPO) further improved decision timing, adaptability, and robustness under fluctuating noise and overlapping sound events. Reward-driven optimization reduced false-positive rates by up to 66% and decreased detection latency by more than 60%, enabling the system to react faster and more confidently to critical acoustic events such as sirens, collisions, and in-vehicle alerts. Deployed through framework which supports large-scale fleet integration, real-time dashboard reporting, and continuous learning across distributed edge agents. The proposed hybrid ML-RL audio framework thus transforms conventional vehicle monitoring into an adaptive, self-improving decision system, bridging the gap between static classification and real-world autonomous driving intelligence.
