What does trips per hour mean in NEMT?
Trips per hour is a NEMT productivity measure: completed one-way trips divided by the hours a vehicle or driver was in service. A van that finishes 10 trip legs in an 8-hour shift runs 1.25 trips per hour. It shows how much billable work each paid hour produces, and it drops when deadhead, long waits, and no-shows eat the day.

How to calculate trips per hour
The formula is simple:
Trips per hour = completed one-way trips ÷ hours in service
The choices behind the two numbers matter more than the division.
- Count legs, not round trips. A round trip is two legs. MTM assigns every trip as an A leg and a B leg, so leg counts line up with broker reports.
- Count only completed legs. A no-show or a late cancellation used time but produced nothing to bill.
- Pick one definition of hours and keep it. Shift hours, from clock-in to clock-out, tie the number to what you pay drivers. They include deadhead, waits, and breaks.
Transit agencies measure a narrower version. The FTA’s National Transit Database counts vehicle revenue hours, the hours vehicles travel in revenue service, and excludes deadhead. For a NEMT business, shift hours are the more honest base, because you pay for every one of them.
A worked example
Here are three hypothetical drivers on the same day. These are illustrations, not benchmarks.
| Driver | Work | Shift hours | Completed legs | Trips per hour |
|---|---|---|---|---|
| A | Urban ambulatory | 8.0 | 12 | 1.50 |
| B | Suburban wheelchair | 8.0 | 9 | 1.13 |
| C | Rural stretcher | 10.0 | 5 | 0.50 |
Driver C is not the weak performer here. Long rural legs pay more mileage, so C may earn as much per hour as A. That is why trips per hour belongs next to revenue per hour, not in place of it.
What moves the number
- Trip length and deadhead. Every empty mile between legs is time with no trip in progress.
- Loading time. Securing a wheelchair or loading a stretcher takes longer at each stop than an ambulatory pickup.
- Waits and no-shows. MTM’s general handbook sets a 10-minute wait before a no-show, and CareOregon sets at least 15. A few no-shows a day add up.
- Will-calls. A driver held near a clinic for a return is not completing trips.
- Appointment windows. Louisiana requires arrival at least 15 minutes and no more than two hours before an appointment, which limits how tightly you can stack morning trips.
- Multi-loading. Two riders on one run complete two legs in one drive, which raises the number when rider mix and ride-time limits allow it.
Trips per hour is one of the core NEMT KPIs. Read it alongside vehicle utilization, and use the profit per vehicle calculator to see what a change is worth in dollars.
Measuring it from real shifts
HealthRide’s driver activity and timecard reports take hours from real clock-ins and trips from the actual schedule, so both numbers you divide come from what drivers did, not estimates.
Frequently asked questions
- What is a good trips per hour number for NEMT?
- There is no universal benchmark, because the number depends on trip length, service level, and how spread out your riders are. A rural stretcher operation and an urban ambulatory one will not look alike. Compare each driver and route against its own history and against similar work in your fleet.
- Should a round trip count as one trip or two?
- Count legs. A round trip is two one-way legs, and brokers such as MTM assign them that way. Counting round trips as one hides half the work and makes your numbers impossible to compare with broker reports.
- Should no-shows count as trips?
- No. Count only completed legs. Track no-shows and cancellations separately, since each one used time without producing a billable trip. That gap is exactly what the measure should reveal.
