Trade & Routing

Busiest Sea-Lanes

The busiest port-to-port lanes our routing layer covers, ranked by a transparent traffic proxy that blends port throughput at each end with observed destination demand and the length of the haul. The index is a relative popularity score, not a surveyed vessel count. Tap any lane to price the voyage in the route planner.

Ulsan → Port of Busan

Of the 400 ranked lanes, Port of Rotterdam is an endpoint of 94 and Port of Singapore of 81 — two harbours anchor 43% of the covered network. A corroborating demand signal reaches 98% of these lanes; the remaining 8 rank on port throughput alone.

Top 12 lanes by traffic index

The relative popularity index (busiest covered lane = 100). It ranks lanes consistently within a snapshot — the order and the trend are the trustworthy signal, not the magnitude.

Ports that anchor the network

Ranked lanes touching each port at either endpoint. A lane counts toward both its ports, so these shares are per-endpoint, not a partition of the network.

Method & caveats

What this is. A ranking of the busiest port-to-port lanes our routing layer covers. Distances are our own navigable sea distances (Suez / Panama / Malacca aware).
Traffic index scores a lane high when a busy load port feeds a busy / observed-demand discharge port over a short haul, rescaled to 0–100 within the snapshot. It is a relative popularity index, not a surveyed vessel count.
Inputs. Port throughput at each end (30-day mean); the discharge end is additionally weighted by the observed destination pull toward it — the count of distinct vessels seen heading to that port, not their dwell time. Distance is discounted so long-haul trades stay comparable to short dense ones.
Segment is the coarse class both ports agree on from their trade composition, else Mixed — mirroring the canonical classifier.
Confidence is never “high”: a ✓ marks lanes where both ends carry port-trade rows and the discharge end has an observed destination signal (the demand pull is corroborated). The rest are inferred from throughput alone. True origin→destination matched voyages would be needed for a surveyed count, which we do not yet hold.
