According to the abstract released by the Intellectual Property India: "Honk-Aware Contextual Lane-Adaptive Traffic Signal Control with Fairness and Behavioural Penalties This invention describes an intelligent traffic-signal control system and method are disclosed for honk-aware, context-weighted, lane-wise adaptive signal timing at regulated intersections. The system detects lane-attributed honk events and extracts multi-feature honk metrics including honk rate, intensity above ambient, inter-honk gap structure, and temporal clustering. A Honk Behaviour Index (HBI) is computed per lane from the metrics and is scaled by a Context Modifier (CM) to reflect contextual traffic conditions. In parallel, a capacity-normalized Lane Load Index (LLI) is determined from real-time lane-wise vehicle density or count. The system fuses the context-adjusted HBI and the LLI to compute an Adjusted Honk Behaviour Index (AHBI), from which lane priorities are derived to allocate green time proportionally within a cycle. A round-robin minimum-green fairness policy guarantees baseline service to each lane to prevent starvation. A selective bounded nonlinear penalty is applied only to lanes exhibiting persistent excessive honking by reducing discretionary priority or green time in subsequent cycles, thereby reducing noise pollution and improving traffic discipline and throughput."
