What those two numbers mean

Passengers aboard is passenger miles divided by vehicle miles: how many people are on board on average, at any moment. It is the missing term in cost per ride. A service carrying twenty people per vehicle mile and one carrying half a person can spend the same on fuel and wages and arrive at wildly different costs per passenger.

Average speed is vehicle miles divided by vehicle hours, including every stop and every red light. It is the hidden term in cost per mile, because cost per mile is cost per hour divided by speed. A bus network slowing from 13 mph to 11 becomes a fifth more expensive per mile with no change in wages and no change in service.

Why cost per ride moved

Indexed to FY2015 = 100

Cost per ride is the cost of an hour of service divided by the riders carried in that hour. It can only rise for two reasons: service got dearer to produce, or fewer people rode it.

Since FY2015 an hour of service costs +125.3% more to run, while carrying -25.2% as many riders. Most of the rise in cost per ride is the service itself getting dearer.

Where the money goes

Operating cost by function

Who pays for it

Federal, state and local funding, 1991 to 2024

Operating and capital money together, in the dollars of each year. Fares are not in this file — FTA took them out of the funding series in 2022 — so "directly generated" here means advertising, concessions, park and ride and taxes the agency levies itself. The farebox is charted above.

Capital

Capital spending

What was spent on building, rebuilding and replacing, shown beside the cost of running the service rather than folded into it.

Cost per ride including the vehicles

An estimate, and the only part of capital this data can honestly support.

Operating cost per ride
$13.88
Plus fleet consumed per ride
$1.31
Cost per ride including vehicles
$15.19
$84.3M of fleet consumed a year

How this is worked out. FTA publishes what every agency spent on rolling stock each year since 1992. Restate all 33 years in today's money and average them over 14 years, the working life of this agency's vehicles, and the result is what the fleet costs to keep going each year. That is straight-line depreciation, and the series covers more than two full replacement cycles.

How much to trust it here. Very little of this agency's fleet spending falls in the last 4 years. Replacement has slowed, so the average rests on older purchases and probably understates what replacing this fleet would now cost.

What it leaves out. Every tunnel, track mile, bridge and station. Those last forty to a hundred years and the data goes back 33, so averaging it would measure recent investment policy rather than what the infrastructure costs. The honest ceiling on this data is operating cost plus vehicles, and this is it.

Capital spending since 1992

In 2024 dollars, so the years can be compared. This is the series the estimate above is built from.

Operating and capital, per ride

Stacked, but counted separately. The two are different kinds of number.

Building, or keeping what exists

FY2024. NTD records which of the two every dollar was reported under.

Who pays for what

FY2024. Running the service and building it are funded by different governments.

Total Federal State Local Fares and own revenue
operating $1.03B 5% 0.1% 1.3% 14.3%
capital $54.7M 18.8% 9.4% 0% 0%

Fares offset the cost of running the service. They do not meaningfully offset capital, which is why subsidy per ride on this site is an operating figure and stays one.

What these capital figures are not

Spending is not the same as cost
NTD reports what an agency spent on capital in a year, not what its capital cost it that year. Those differ: a system opened in 1904 spends almost nothing on tunnels while consuming an enormous inherited asset every day, and an agency that bought a fleet last year spent a fortune once and will spend nothing for a decade.
Vehicles can be depreciated. Everything else cannot.
FTA's capital series runs from 1992, which covers a bus fleet's working life more than twice over, so averaging rolling-stock spending across one replacement cycle gives a defensible figure for what the fleet costs each year. Track, tunnels, bridges and stations last forty to a hundred years or more. Thirty-three years of spending on those measures recent investment policy, not consumption, so no figure is published for them.
The vehicle figure is an estimate
Cost per ride including vehicles is arithmetic on published spending rather than a published number, and it assumes the agency has been replacing vehicles at roughly the rate it wears them out. Each agency's page says how far that assumption holds for it. It covers vehicles only: no track, no tunnels, no stations.
Year-by-year capital is lumpy
Capital arrives in bursts. A single year of it says more about where an agency sits in its replacement cycle than about the cost of carrying a passenger, which is why the per-ride averages here run across every year available.
Fares do not pay for it
Fare revenue offsets operating cost. It does not meaningfully offset capital, which is funded almost entirely by government. Subsidy per ride on this site is an operating figure and stays that way.

Events by year

All event types, all modes

Events per 100 million revenue miles

This agency against the national rate, on the same axis

Miles rather than boardings, because this series covers 2020: service kept running when riders stopped coming, and a rate per boarding would read that as a collapse in safety. Sitting above the national line is as likely to mean careful reporting as dangerous operation — and rail systems report events on their own right of way that a bus operator never encounters.

The longer record, 2008 to 2024

FTA's threshold-adjusted time series, which reaches back further than the incident file and is built to be compared across years

NTD's reporting threshold changed in 2010, 2015 and 2023. FTA publishes this series adjusted for those changes so the years can be read against each other; the unadjusted counts jump by a third in 2015 on the rule change alone.

Injuries, latest full year

Who died, 2025

The total is not a measure of risk to riders, and NTD gives the breakdown that shows why.

Of 3 deaths, 0 were passengers. Most of the rest were people on the track or the road, and 0 were suicides.

Set against distance travelled, that is deaths per billion passenger miles counting everyone, and counting riders alone — a difference of roughly eight times.

Both are true. They answer different questions: the first is how many people die in connection with transit, the second is the risk of being on board. Quoting the first as the second is the commonest way these figures are misread.

Individual incidents

NTD publishes every major event on its own, with a time and usually a place. 1,594 of them for this agency since 2014, including 5 assaults on transit workers.

How the fleet has aged, 1992 to 2024

Average vehicle age, weighted across every mode the agency runs

A rising line is not automatically bad and a falling one is not automatically good: a fleet gets younger the year an agency takes delivery, and older every year it does not. What the shape shows is whether replacement is steady or comes in bursts. The table below says how many vehicles are actually past the life FTA expects of them.
