Every trailer on the plot. Every dock booking true.
Yard and trailer management RTLS — find the trailer before the dock window dies. Identity reconciled to YMS so every booking is true.
Yard RTLS fails when the yard board and the WMS disagree on what is on site.
Check-in truth
If gate check-in is verbal, the map starts wrong. Automate identity at the gate before you optimise parking slots.
Detention maths
Detention and demurrage claims need timestamps the carrier accepts. Design the evidence pack, not only the pretty map.
Spot discipline
Without enforced slot assignment, drivers park by habit and the RTLS only documents chaos. Process first, radios second.
Yard & trailer management: how it works, and what it pays back.
The right radio for the job — chosen, never sold — mapped to your use case. That is what makes the ROI fast.
1 · Tag & gate
Trailers carry GPS/BLE tags; gate reads log every entry and exit automatically.
2 · Locate & time
The yard map shows each trailer's slot and live dwell, so detention risk surfaces early.
3 · Sequence
Dock and shunt moves are sequenced to the WMS — right trailer, right door, right time.
GPS → outdoor yard · RFID → gate & slot reads
Which technology actually fits.
Paid only by you. Hardware stays on the vendor’s paper.
BLE/GPS
Yard-wide trailer location.
Passive RFID
Automated gate check-in.
Integration
Live feed to TMS/YMS.
Industries this solution suits
The right trailer at the right door.
A 3PL tags its trailers and automates gate reads. The yard map shows each trailer's slot and live dwell, detention risk surfaces early, and dock and shunt moves are sequenced straight to the WMS.
Typically bought by: Yard / transport managers, 3PL operations, dock supervisors.
Relevant case studies
Where this solution wins — examples by sector.
3PL multi-yard operations (logistics)
Yards holding hundreds of trailers; GNSS or LoRaWAN trackers reduce search time 90%+.
Retail DC yard management (retail)
DC-to-store and DC-to-DC trailer flow.
Cold-chain yard with refrigerated trailers (logistics)
Refrigerated trailer monitoring + yard visibility combined.
Automotive finished-vehicle yards (automotive)
Thousands of vehicles awaiting dispatch.
Container terminal yard management (logistics)
Container yards at ports with thousands of moves per day.
Who needs this kind of programme.
3PL, retail DC and manufacturing yards burning money on detention, wrong-door shunts and lost trailers.
Transport and yard managers whose whiteboard or radio culture cannot scale peak volume.
WMS/YMS owners who need gate and slot truth that matches the warehouse system of record.
What buyers compare in this market.
The market splits between classic YMS platforms (Kaleris/C3-class) that integrate RFID/GPS/IoT, RAIN portal vendors (Impinj/Zebra dock and gate reads), GNSS trailer tags (u-blox and telematics peers), and newer vision/AI yard systems that reduce tagging. Pure software YMS without physical identity still depends on human check-in; pure GPS without dock portals still mis-assigns doors.
TRACIO scopes which events must be automatic (gate in/out, dock occupancy, dwell timers) and which technology mix keeps the yard board and WMS aligned.
Why yard programmes fail.
YMS and WMS disagree. Two inventories of “what is on site” guarantee detention arguments.
Hardware without shunt rituals. A live map that dispatchers ignore is expensive art.
Carrier exception blind. Drop-and-hook partners outside your process recreate the lost-trailer problem overnight.
Independent. Vendor-neutral.
We sell no YMS licences and no portal kits. We advise RFID vs GNSS vs vision for your yard geometry, and integrate events into the WMS/TMS you already run.

Frequently asked questions
What problem does yard and trailer management solve?
The 'lost trailer' yard - hunting for units, idle drivers, and detention charges. Real-time location of trailers and assets turns the yard into a visible, scheduled operation.
How are trailers and the yard tracked?
A mix of GPS or cellular or RTLS tags on trailers, plus gate RFID and dock sensors, gives live position, dock status and dwell across the whole yard.
Can it automate gate and dock processes?
Yes - automatic gate check-in and out, dock-door assignment and dwell timing remove manual paperwork and surface detention before it costs you.
How does it integrate with our YMS, WMS or TMS?
Yard events feed your YMS, WMS and TMS via API so trailers and appointments are coordinated end to end with the warehouse.
What is the payback?
Less driver and shunter time hunting, lower detention and demurrage, faster dock turnaround, and accurate trailer inventory - a quick win for busy DCs.
