Abstract: Enforcing vehicle speed limits is paramount for road safety. This paper pioneers an innovative approach by synergizing signal processing and Convolutional Neural Networks (CNNs) to detect speeding violations, addressing a critical aspect of traffic management. While traditional methods have shown efficacy, the potential synergy of signal processing and AI techniques remains largely unexplored. We bridge this gap by harnessing Mel spectrograms extracted from vehicle recordings, representing intricate audio features. These spectrograms serve as inputs to a tailored CNN architecture, meticulously designed for pattern recognition in speeding-related audio cues. An altered variant of the crayfish optimization algorithm (COA) was employed to tune the CNN model. Our methodology aims to discriminate between normal driving sounds and instances of speed limit breaches. Notably absent from previous literature, our fusion method yields promising initial results, demonstrating its potential to accurately identify speeding violations. This contribution not only enhances traffic safety and management but also provides a pioneering framework for integrating signal processing and AI techniques in innovative ways, with implications extending to broader audio analysis domains.
