Yard KPIs & Metrics to Track

A yard without metrics runs on anecdote — the loudest complaint about a late truck gets attention, while a slow, systemic problem goes unnoticed for months. A focused set of yard KPIs turns the daily chaos of gate traffic, dock assignments, and trailer moves into numbers that show whether the yard is actually getting faster, slower, or staying the same.

Time-based metrics are the foundation because almost every yard cost — detention, labor, missed appointments — is a function of how long something sits or waits. The two most important are dwell time and gate-to-dock time.

• Trailer dwell time — total time a trailer spends in the yard from check-in to check-out, broken down by loaded/empty and by reason (waiting for dock, waiting for product, waiting for paperwork)
• Gate-to-dock time — elapsed time from gate check-in to the trailer being spotted at an assigned door
• Dock occupancy time — how long a trailer actually occupies a door once spotted, versus the planned slot duration
• Detention-triggering dwell — percentage of trailers exceeding the free-time threshold that triggers carrier detention charges

Throughput metrics answer "how much is moving through the yard" while utilization metrics answer "how well are we using what we have." Both matter — a yard can have great throughput and still be inefficient if it takes twice the trailer fleet it should need to achieve that volume.

• Trailers processed per day/shift, by dock and by yard overall
• Dock door utilization — percentage of available dock-hours actually occupied by a trailer being loaded/unloaded
• Yard jockey moves per hour and non-productive move ratio
• Appointment adherence rate — percentage of arrivals within the scheduling grace window

Time and throughput metrics eventually convert into money and risk. Detention and demurrage cost by carrier shows where poor scheduling or slow processing is generating avoidable expense. Seal exception rate and gate compliance rate (percentage of gate checks completed to full checklist standard) show whether security processes are being followed under normal operating pressure, not just during audits.

• Detention/demurrage cost, total and by carrier
• Seal exception rate per 1,000 trailers processed
• Gate check completion rate against the full checklist
• Yard accident/near-miss rate — a lagging but critical safety indicator

The value of KPIs comes from consistent tracking and visible trends, not from a single snapshot. A useful yard dashboard shows current-shift numbers next to a rolling 7- and 30-day trend, with thresholds that turn a metric red when it crosses an agreed limit (for example, average dwell time exceeding two hours). Reviewing the same five or six numbers daily in a short stand-up meeting does more to improve yard performance than a monthly report that arrives after the problem has already cost money.

• Pick 5-8 metrics maximum for the daily dashboard — more becomes noise
• Show trend, not just current value, so improvement or decline is visible
• Assign a metric owner responsible for investigating red thresholds
• Revisit target thresholds quarterly as the yard's baseline performance changes
