How many trips a NEMT van can do in a day: the math and the limits

The short answer: minutes per leg decide it

A van’s daily trip count is its working minutes divided by the minutes each trip leg really takes. Everything else is detail about what goes into those two numbers. Planning around a guessed figure can leave you a van short on busy mornings and paying a driver to sit through slow afternoons.

Count one-way legs, not round trips. Taking a rider to dialysis and bringing them home counts as two legs, and brokers schedule, pay, and score them separately. For example, the Virginia handbook MTM Health approved on August 10, 2026, for fee-for-service rides from October 1, 2026 onward, gives the first pickup of a scheduled trip, the A leg, its own pickup window.

The four pieces of every leg

Each leg a van runs is made of four blocks of time:

1. Pickup stop. Parking, announcing arrival, waiting for the rider, giving the assistance on the manifest, and securing the rider. The pickup and drop-off guide breaks this block down by mobility level.
2. Loaded drive. The ride itself, from pickup to destination.
3. Drop-off stop. Unloading, walking the rider in, and any check-in the service level requires.
4. Empty drive. The drive from this drop-off to wherever the next rider waits. These are your deadhead miles, and they cost the same fuel and wages as loaded ones.

Add the four and you have minutes per leg. Two of the blocks depend on the rider and two depend on geography, which is why the same van produces very different counts in a city and in the country.

Working minutes in a shift

Start from the shift, then take out the time the van cannot carry riders.

• Meal and rest time. Federal wage law does not require breaks. The Department of Labor counts short breaks as paid work time, and it describes them as usually 5 to 20 minutes long. Meal periods of at least 30 minutes are unpaid. Many states add their own rules. California requires a 30-minute meal period when work runs more than 5 hours, and a second one past 10 hours.
• The vehicle check and the first drive. A pre-trip inspection and the drive from your lot to the first pickup use shift time before any leg starts.
• The end of the day. The last drop-off is rarely at your lot, so the drive back belongs in the shift too.

For the examples below, a 10-hour shift keeps 570 working minutes after a 30-minute meal period. The inspection and the drives to and from the lot fall into the allowance in the table below.

Worked examples: urban, suburban, rural, and stretcher

These are examples with assumed times, not benchmarks. Replace every number with your own averages once you have a few weeks of trip records.

The last row is the realistic one. The 80% allowance covers time the van spends neither carrying a rider nor heading to one: early arrivals it cannot board yet, gaps between the morning and afternoon rushes, will-call holds, and no-shows. It is an assumption. Your own share comes from your records: completed legs times your average minutes per leg, divided by the shift’s working minutes.

Read the results this way: about 12 or 13 legs for the urban ambulatory van, about 8 for the suburban wheelchair van, and 5 or 6 for rural or stretcher work. Rural and stretcher vans land in the same place for different reasons. The rural van spends its time driving, while the stretcher van spends it at the curb and in the building.

A public benchmark helps as a sanity check. In report year 2024, the Federal Transit Administration’s National Transit Database shows demand-response services reported by transit agencies logging about 139.7 million boardings and 72.6 million hours of revenue service, which works out to roughly 1.9 boardings for every revenue hour. Those services often carry several riders at once, and revenue hours exclude deadhead travel, such as trips between the garage and the first or last stop. A van carrying one rider at a time and measured against its whole shift should expect a lower figure.

Why appointments cap the day before the shift does

Most NEMT demand arrives in bunches, and a van can only be in one place during the rush. Payer rules make the bunching tighter:

• Arrival deadlines. MTM Health’s Virginia handbook has riders dropped off by the appointment time at the latest, with time left over for entering the building and checking in.
• No early boarding. The same handbook, Georgia’s manual, and CareOregon’s manual all bar drivers from making a rider leave ahead of the scheduled pickup time. A van that arrives early waits.
• Will-call returns. Virginia gives the van 45 minutes from the rider’s call to arrive, and Georgia gives it one hour. Meeting that often means keeping a van near the clinic instead of running other legs. The will-call guide explains where to stage vans for it.
• Dialysis chair times. NIDDK notes that people treated at a center are given a set slot, typically on three days a week, with treatments of roughly 4 hours. Arrivals for a shift bunch at its start and departures at its end.

Here is how the peak caps a van, using the urban example. If most arrivals fall between 7:30 and 10:30 a.m., a van at 36 minutes per leg fits about 5 of them into those 3 hours, however long the shift is. A book with 30 morning arrivals needs 6 vans in that window, even if the whole day’s legs would fit on fewer. The fleet size calculator runs this peak check for a whole schedule.

Bunching also creates chances. When one dialysis shift ends close to when the next begins, a van can drop off an arriving rider and collect a departing one at the same door, with no empty drive between the two legs.

Why wheelchair and stretcher vans run fewer legs

The loaded drive is the same whatever the rider’s mobility. The stops are not.

• Wheelchair legs. MTM Health’s Virginia handbook calls for a full set of four working securements at every wheelchair position, each with a lap and shoulder belt fixed to the van, and drivers must check that every wheelchair and its rider are tied down before the van moves. Add the lift cycle at both ends and a wheelchair stop runs well past the time it takes to seat a rider who walks.
• Stretcher legs. Virginia’s handbook has riders loaded headfirst and strapped at the chest, hips, knees, and upper body on a crash-tested stretcher mount. The provider also brings a scoop, Reeves, or stair chair stretcher whenever a rider needs that equipment. A hospital discharge adds the walk to the unit: CareOregon’s manual sends the driver to the nurse’s station with the right equipment.
• Door service in buildings. New York’s Medicaid transportation manual has ambulette staff collect riders at their own front door, even a nursing home room several floors up, and take them to the doctor’s door, however many stairs that takes.

Fewer legs do not have to mean less money. These legs are billed under their own codes, A0130 for a wheelchair van and T2005 for a stretcher van, so fee schedules price them apart from ambulatory rides. Judge a wheelchair or stretcher van by revenue per vehicle hour, not by how many legs it runs.

How to fit more legs into the same shift

Each of these cuts minutes from the average leg or fills minutes the van now spends waiting:

1. Chain drop-offs to nearby pickups. The empty drive is the easiest block to shrink. The deadhead guide lists the tactics.
2. Start drivers where the work is. Staggered starts near the first pickups cut the morning drive from the lot and match vans to the rush. See building driver shifts.
3. Fill the midday gap. Same-day requests, hospital discharges, and pharmacy runs can fill the hours between the morning and afternoon peaks. Virginia’s handbook tells providers to keep vehicles and drivers in reserve so they can take urgent trips assigned on short notice.
4. Cut no-shows. Each one costs the wait before the driver may leave (10 minutes in Georgia, at least 15 under CareOregon’s manual) plus an empty drive to the next rider. Reminder calls and texts protect those minutes; see reducing no-shows.
5. Share rides if the payer permits it. Keep each rider within the 45-minute extra ride time that Virginia and Georgia allow on shared runs. The multiloading guide shows how to plan them.
6. Work in zones. Keeping each van in one area shortens both the loaded and empty drives. See zone dispatching.
7. Ask facilities to spread their times. A dialysis center or day program that staggers arrivals by 15 minutes can take a van off your morning peak.

Check the estimate against real shifts

An estimate is only a starting point. Each week, compare legs completed with working hours for every van, and look at the four blocks separately so you know which one to fix. Trips per hour is the simplest version of that measure, and it belongs on your list of NEMT KPIs next to on-time performance.

The same records tell you when to buy another van. If your vans already run full through the morning rush and you still turn down or run late on trips in that window, you need more capacity, and the trips you turn away show which kind: ambulatory, wheelchair, or stretcher. If the lost time sits in midday gaps, long empty drives, or waits, fix the schedule first. A new van added to a loose schedule mostly adds cost.

Planning the day with software

In HealthRide, Ryder Go lets you plan your whole day in one click, and each rider’s wheelchair, stretcher, or oxygen needs go to a vehicle that can carry them. The driver and timecard reports then set completed trips against real clock-in hours, so every assumption in this guide can give way to your own numbers.
