How to Investigate Capacity Utilization Across Routes

Capacity is only valuable if it is used on freight that pays. Comparing each route’s share of miles with its share of contribution shows where capacity is working hard and where it is not.

1. The business problem

Are we putting our capacity where it earns the most?

A fleet’s capacity is divided among lanes, often by habit or by customer demand. Over time some lanes grow and others shrink, and capacity may not follow profit.

Comparing share of miles with share of contribution shows whether capacity is earning its keep, and where moving it would help.

2. What the evidence can reveal

A capacity allocation view compares two shares for each route:

  • Calculated Share of loaded miles: how much of the fleet’s capacity the route uses.
  • Calculated Share of contribution: how much of the profit pool it earns.
  • Calculated The ratio of the two: above 1 means the route earns more than its share.
  • Information gap Whether capacity could actually be moved, which depends on customers, equipment type and driver base.

The aim is to find routes where capacity is under-earning relative to alternatives that could absorb it.

3. Investigate the problem

In the synthetic carrier, Calculated cross-country spot used about 17% of loaded miles (1,260 thousand of 7,350 thousand) but earned only about 9% of the contribution ($400K of roughly $4.6 million). Its share of miles is growing: miles rose 14.5%.

Calculated The opposite pattern shows in Regional LTL and Port drayage. LTL used about 11% of loaded miles and earned $830K of contribution, about 18%. Port drayage used about 9% of miles and earned $900K, about 19%.

Hypothesis Capacity may be flowing to lanes where freight is easiest to find, not where it earns the most. Information gap Whether capacity could shift to LTL or port work depends on demand there, equipment types and driver familiarity, none of which is in the demo. The finding is a question to test, not a conclusion.

4. Explore the interactive experience

Investigate it yourself.

Fleet Economics Dashboard: a lane-level dashboard with empty-mile share, a scenario simulator for rate, fuel, miles and empty miles, evidence-linked answers from APIS, and a sample brief, all on synthetic data.

The experience below is built on a synthetic carrier, “Demo Freight Co.,” analyzed by lane. It has no customer-level, vehicle-level or delivery-level records, so lanes are used to show the method. Nothing in it is real.

  1. In the lane table, compare Loaded miles (000) with Contribution across lanes. Which lanes use the most capacity for the least return?
  2. In the Scenario tab, raise loaded miles by 5%. How much does the extra volume add if the margin stays as it is?
  3. Ask APIS which lanes warrant a closer review.

5. Evaluate possible solutions

Reallocating capacity needs demand, equipment and drivers to line up.

Shift capacity toward higher-margin lanes

When it may fit: Demand exists in better lanes.

Evidence needed: Demand and customer capacity.

Trade-off: Equipment and drivers may not fit.

Reprice low-contribution lanes

When it may fit: Capacity is held by weak lanes.

Evidence needed: Lane cost and market rates.

Trade-off: May lose volume.

Set capacity limits by lane

When it may fit: Weak lanes expand by default.

Evidence needed: Target shares of capacity.

Trade-off: Reduces flexibility.

Grow capacity only for high-margin lanes

When it may fit: New capacity would otherwise be spread thin.

Evidence needed: Return on new capacity by lane.

Trade-off: Capital and hiring.

6. What leadership should do next

Questions to answer

  • Which lanes earn more than their share of capacity?
  • Which earn less?
  • Can capacity move?
  • Where is demand?

Data to gather

  • Miles and contribution by lane
  • Demand pipeline by lane
  • Equipment suitability
  • Driver skills and preferences

Steps to take

  1. Compare shares of miles and contribution.
  2. Pick one reallocation test.
  3. Measure for a quarter.
  4. Repeat.

7. Engage Two Pillars

Understand the Economics of Your Fleet

Two Pillars can help carriers, fleet operators, brokers and logistics businesses investigate lane, vehicle, customer, cost and expansion economics using your own data. A good first step is a capacity-allocation review comparing miles and contribution by lane.
