HLSR: Hybrid Live Forecast Selective Dynamic Vehicle Rerouting for Real-Time Congestion Avoidance

HLSR is a selective hybrid live‑forecast vehicle rerouting framework designed to reduce urban traffic congestion. It combines live edge speeds with short‑horizon forecasts, using dual‑threshold congestion detection, calibrated upstream selection, and driver‑tailored travel‑time prediction. The method introduces approaching‑vehicle expansion, travel‑time‑weighted k‑shortest‑path generation, and a horizon‑dependent hybrid live‑forecast segment speed for multi‑cost route allocation.
