summary

Claim: intersections are urban bottlenecks whose throughput and delay are set by cycle length, phase durations and offsets. Uses detector logs and historical phase durations, models actuated logic as min green / extension / gap-out, predicts remaining green by the conditional expectation of residual duration from past cycles, and computes eco‑driving speed profiles by dynamic programming. Experiments and simulations report an eco‑driving fuel reduction of up to ~20%, while dynamic offsets remain hard to solve in networks.
