Adaptive Approach Gate
First-line vehicle screening at the port boundary. Multi-lane ANPR identifies every approaching vehicle before they reach the gate.
Four lenses on every approaching vehicle.
Adaptive Approach Gate captures four streams of data in a single pass — long before a vehicle reaches the gate. The result: every truck, car, and bus is already classified and timed when the gate opens.
Every approaching vehicle is measured in motion — height, width, and length captured by LiDAR, its class identified, and its speed and direction clocked on the run. The full profile is known before the vehicle reaches the gate, ready for tariff, oversize checks, and deck planning.
01
Multi-lane ANPR Recognition
Read every license plate across every lane simultaneously, day and night, at a constant 30 to 70 km/h.
02
Vehicle Classification
Distinguish trucks, vans, cars, buses, and motorcycles automatically — feeding lane logic and tariff systems downstream.
03
Speed Measurement on Approach
Live velocity readings let the system anticipate arrival timing and flag vehicles outside the safe approach envelope.
04
Dimension Capture
Height, width, and length captured in motion — ready for tariff calculation, oversize detection, and deck planning.
From approach to record — in under a second.
THE RECORD
What one approach pass captures.
A single free-flow pass produces one record, and this is its shape: images, identity, class, geometry and motion, all bound to the same event. Everything below is delivered through documented APIs — nothing is locked in a proprietary export.
Values shown are one illustrative event. Fields marked as an option are fitted only where a site asks for them.
What every crossing writes to GDS.
One free-flow pass produces one complete, time-stamped event record. Reads are guaranteed in free flow from 30 to 70 km/h, with no stopping and no tailgating required. What matters is a constant speed through the gate: accelerating or braking under the gantry is what costs accuracy, not the speed itself.
| Data | What's recorded | Delivery KPI |
|---|---|---|
| Event metadata | Site, lane, event ID, timestamp — the backbone every other field hangs on. | 99.5% counting |
| Number plate | Front and rear plate with country of registration. | 99.7% read · 99.7% nationality |
| Make & model | Manufacturer and model recognised per vehicle. | per event |
| Vehicle class | Classified into vehicle categories. | 98% |
| Dimensions | Height, width, and length measured by LiDAR in the same pass. | per event |
| Speed & direction | Lane-accurate speed and direction of travel. | ±5 km/h |
| Axle weights | Optional weigh-in-motion: gross weight, per-axle weight, axle spacing. | optional · where fitted |
| Image evidence | Front and rear overview plus plate close-ups, attached to the event. | every event |
KPIs are the acceptance thresholds our deployments are contracted to meet — not lab bests. Vehicles outside the measurement envelope are still recorded; the contracted accuracy figures simply no longer apply. Rows marked optional are fitted only where a site asks for them — weigh-in-motion above all, which several of our approach gates run entirely without, and which is third-party equipment procured separately.
Operating envelope
Deployment footprint: gantry mounting with sensors at 5 m or higher, lane widths from 2.5 to 3.75 m, and one gate control PC per 2 lanes. Options: weigh-in-motion, OBU/DSRC reader, and dual-direction operation with wrong-way alerts.
THE CAMERA · VIDAR ANPR
The camera doing the reading: Vidar.
Every plate, class, and dimension in the event package starts here. Vidar is Adaptive Recognition's all-in-one ANPR camera — more than two decades of R&D condensed into a single weatherproof unit that images, decodes, and classifies vehicles on the move, with the Carmen engine running on board. One device covers up to two lanes, triggers itself, and streams finished reads straight to the Globessey Data Server.
Carmen ANPR + MMR on board
The only ANPR camera that runs the Carmen engine itself — plate, make, model, and country resolved in-camera, with no separate recognition server in the loop.
Reads at real traffic speed
Free-flow recognition from a standstill to full lane speed, day or night, on coloured, reflective, and non-reflective plates alike.
Two lanes, one camera
A single Vidar covers up to two lanes and detects vehicles on its own — built-in hardware and software triggers, no external ground loop required.
Serious on-board compute
Two four-core CPUs run high-FPS video, ANPR, make-and-model, and data streaming in parallel — nothing queues behind anything else.
Self-adjusting optics
An on-board gyroscope, accelerometer, and laser keep zoom and focus sharp as conditions change — no manual re-tuning after install.
Built to integrate
A documented API with PUSH and PULL data streams drops the finished read into GDS, your TOS, or a tolling backend without custom glue.
The hardware and software behind Adaptive Approach Gate.
THE HARDWARE
Vidar ANPR Camera
All-in-one ANPR camera with the Carmen engine on board, IR illumination, and up to five-megapixel imaging. Two four-core CPUs stream video, read plates, and recognise make-and-model in parallel — one weatherproof unit covering up to two lanes, engineered for outdoor 24/7 operation.
THE ENGINE
Carmen FreeFlow
Adaptive Recognition's ANPR engine — proven in over 100,000 systems worldwide. Reads plates without zones or triggers, in any orientation, and adds make, model and colour. Engine updates ship four times a year, so new plate designs are covered without touching the hardware.
THE ENGINE · CARMEN FREEFLOW
One engine reads them all.
Carmen FreeFlow is the recognition core inside every Adaptive Approach Gate — the same OCR engine proven in over 100,000 systems worldwide. It reads more than 60,000 plate types across 160+ countries, in Latin, Arabic, Cyrillic, and Thai scripts, and returns make, model, and colour alongside the plate. Engine updates ship four times a year, so new plate designs are covered without touching the hardware in the field.
160+ countries, 60,000+ plate types
One library covers the mixed international traffic a ferry or Ro-Ro port actually sees — no per-market retuning.
Make, model & colour recognition
Beyond the plate: the vehicle is described, so the record can be matched to the booking and cross-checked for fraud.
Dangerous-goods & container codes
ADR hazard plates and ISO container codes are read in the same pass — freight is flagged before it reaches the gate.
Built for enforcement-grade accuracy
Low false-positive rates suit tolling and speed enforcement, where a wrong read costs more than a missed one.
ADR & container codes
Hazmat spotted at the boundary, not at the booth.
Carmen's ADR module reads the orange dangerous-goods placards — hazard number and UN number — and ISO container codes straight off the approaching vehicle. Freight carrying regulated cargo is identified and routed the moment it enters the approach, so it never surprises the gate crew or holds up the vessel call.
SCOPE OF SUPPLY
What we deliver — and what stays yours.
We supply the recognition layer: the cameras, the readers, the engines that turn a moving vehicle into a record, and the data platform underneath. The lane itself — its civils, its power, its steel and its screens — is procured and installed by you or your integrator, to your own standards and suppliers.
Delivered by Adaptive Recognition
- Vidar ANPR cameras, with the Carmen recognition engine licensed on board
- The triggering unit and the profiling sensor the lane is designed around
- The industrial gate control PC that runs the lane
- Globessey Data Server, on your own hardware (optional)
Provided by the port or its integrator
- Gantry, foundations and all civil works
- Electrical cabinet, power supply, cabling and network
- Traffic-control display, barrier or traffic lamp, where the lane needs them
- Weigh-in-motion equipment, where the site weighs at all — procured separately
- Integration into your ticketing system or TOS
We deliver the reading, not the ruling. The record lands in your data layer complete; what happens next — clearing a booking, opening a barrier, raising a tariff — is decided by your own systems.
Where Adaptive Approach Gate earns its keep.
Wherever vehicles cross a boundary at volume, Adaptive Approach Gate gives operators the data they need before the first wheel reaches the gate.
Ferry Terminals
Identify every vehicle joining the queue so check-in staff can match plates to reservations before the booth — no idling, no surprises.
Ro-Ro Ports
Read trailer plates and hazmat codes on arrival so freight rolls through gate validation without slowing the convoy or holding up the next vessel call.
Peak-Season Surge
Pre-identify every vehicle in the approach queue at peak departures so check-in throughput tracks the sailing schedule, not the manual booth rate.
