Yard & dock glossary
Definitions for the terms gate teams, yard jockeys, dock coordinators, and carriers use — with links to Flodock solution pages where a concept maps to product capability.
YMS overviewA
- Appointment
A scheduled arrival window for a truck visit. In a YMS, appointments become operational visits once confirmed and checked in at the gate.
Carrier appointments- Auto confirm
A site configuration where valid carrier booking requests are confirmed immediately without manual yard review.
Carrier appointments- API-first closeout
Automated ERP and TMS sync via REST APIs and webhooks when visits complete — event-driven architecture for the yard management suite.
Integrations- ASN
Advanced Shipping Notice — inbound shipment data that closeout events from the YMS can confirm at gate-out.
Integrations
B
- Bill of lading (BOL)
Shipping document listing freight contents and parties — captured at gate or dock on the visit record for closeout and dispute resolution.
Freight & documents
C
- Carrier portal
A self-service surface where carriers request visits, submit required data, and follow status from confirmation through gate-out.
Carrier appointments- Check-in
Gate arrival event where driver, trailer, and required documents are captured on the visit record.
Gate & yard check-in- Closeout
Final processing when a visit completes — gate-out timestamp, documents, and structured outputs to ERP or webhooks.
Integrations- Connected yard platform
The unified software layer that orchestrates gate, yard map, dock, dwell intelligence, carrier booking, and ERP closeout on one visit lifecycle — the modern way to run a yard management system.
YMS overview- Carrier self-service
Carriers book visits, submit required data, and follow status without calling the gate — through the carrier portal on the same rules engine the yard uses.
Carrier appointments- Computer vision gate
Camera-based gate capture that reads plates, trailer IDs, and equipment — part of AI yard management when paired with operator-approved workflows on the visit record.
AI yard management- Container yard
A yard that stages and tracks shipping containers and chassis — common at intermodal ramps and port-adjacent facilities — managed on the same visit lifecycle as trailer yards.
Container yard management- Chassis
The wheeled frame that carries a shipping container on the road — captured at gate-in with container ID on intermodal and port-adjacent visits.
Container yard management- Container terminal
A port or rail facility where containers are handled — yard management software tracks gate-through-staging visits; terminal operating systems handle vessel or rail plans.
Container yard management
D
- Demurrage
Penalty charges when equipment or cargo exceeds allowed free time on site. Stage-level dwell visibility helps teams act before demurrage accrues.
Trailer dwell time- Dock assignment
Assigning a specific door to a visit, linked to staging status and warehouse notification on the same record.
Dock & yard management- Dock door
Physical loading/unloading bay. In a YMS, door status ties to visit progress and WMS receiving or shipping tasks.
Dock scheduling- Dock scheduling
Managing appointment queues and door calendars. In yard management software, dock scheduling shares the visit record with gate and yard map.
Dock & yard management- Driver capture
Recording driver identity and credentials at gate-in as part of site-configured required fields.
Gate & yard check-in- Dwell
Time a trailer spends on site, tracked by stage — since gate-in, since staged, since at the door.
Trailer dwell time- Dwell alert
Notification fired when a visit exceeds a site-configured time threshold at a given stage.
Trailer dwell time- Detention
Carrier penalty when equipment exceeds agreed free time — predictive dwell and yard intelligence help teams act before detention accrues.
Trailer dwell time- Digital twin yard
Live digital model of yard occupancy and equipment positions — the yard map view of spots, zones, and trailers updated as moves happen on site.
AI yard management- Dock appointment
Scheduled dock door window for a visit — linked to carrier booking, gate check-in, and staging status on the same record.
Dock scheduling- Drop trailer
Trailer left on site without the tractor — tracked as a visit or equipment record with dwell from drop time through pickup or gate-out.
Trailer yard tracking
E
- ERP integration
Sending structured closeout events from the YMS to SAP, Oracle, NetSuite, Dynamics, or custom endpoints.
Integrations- Exception management
Queue of open yard issues — missing documents, lane pressure, stalled closeouts — surfaced on the intelligence panel with age and recommended next action.
AI yard management- Event payload
Structured JSON fields sent at gate-out or other visit milestones via webhook or API — PO, dwell, documents, departure timestamp.
Integrations
F
- Freight capture
Recording load type, PO, seal, and document references at gate or dock — feeds closeout payloads to ERP and dispute audits.
Freight & documents
G
- Gate capture
Structured data collection at arrival and departure: trailer, driver, lane, PO, freight, and documents.
Gate & yard check-in- Gate-in
The event when a truck enters the facility and is recorded on the visit timeline with capture timestamp.
Gate & yard check-in- Gate-out
Departure event closing the visit — final timestamp and audit history for finance and carriers.
Gate & yard check-in- Gate team
Staff at the entrance who check trucks in and out, enforce required fields, and initiate the visit record.
Gate & yard check-in
I

Trailer yard tracking
L
- Live occupancy
