Container Terminal Yard Capacity, Dwell Time & Truck Gate Congestion Tool

Forecast container accumulation, identify yard blocks approaching their practical limits, and test truck-gate appointment and landside-handling capacity. See when a berth discharge surge, longer dwell or a concentrated trucking peak creates queues, overflow, and additional operating costs.

Assessment basis

Fast terminal pressure screen: 12 inputsEstimates a 14-day container inventory trajectory and representative gate queue. The peak-arrival multiplier is a planning shape, not a measured arrival distribution.

Yard Flow & Dwell

Gate Demand & Service

Integrated yard + gate operations modelEdit terminal capacity, yard blocks, vessel surge days and truck appointment windows. Each schedule uses the same inventory and gate algorithms, so scenario differences are traceable.

Model scope: Occupancy uses user-entered TEU-equivalent space capacity, not stack-slot geometry or dangerous-goods segregation. Gate results approximate a fluid first-in/first-out queue with 15-minute intervals, not discrete truck dispatch or individual truck turnaround. The World Bank CPPI measures vessel time in port and is not the score used here.

Yard Block & Inventory Register

Capacity, current occupied TEU, daily inward volume, average dwell and maximum daily departures are independently editable. Use categories rather than actual container IDs.

Use	Block / cargo group	Capacity TEU	Occupied TEU	Arrivals TEU/day	Avg dwell days	Max outflow TEU/day	Day 1 occupancy	Remove

Vessel Discharge / Special Flow Register

Enter incremental arrivals or additional removals for a particular day and yard block. These adjust normal daily flows; outflow remains subject to the block's available inventory and capacity.

Use	Day (1 = first day)	Yard block	Extra inward TEU	Extra release TEU capacity	Operation / reason	Remove

Truck Appointment, Gate & Yard Service Windows

Representative operating day. Enter hours from opening (0–24), trucks arriving in each window, lanes available and the landside handling rate. Overlapping windows are invalid. Gaps imply zero arrivals and zero processing.

Use	From hour	To hour	Arriving trucks	Gate lanes open	Trucks/hr/lane	Yard service trucks/hr	Notes	Remove

Operational Readiness & Control Register

Track yard equipment, truck gates, interchange/TOS availability and exceptional operating limits. Failed or unverified critical items create escalation flags independent of modeled throughput.

Use	Verification item	Area	Critical	Status	Responsible discipline	Remove
