Transport managers are being told that the number of fatalities is up again.
That’s the message from the Department of Transportation’s National Transportation Safety Board, which released a report Monday that shows workplace fatalities increased in the second quarter.
In the first quarter, the board said, there were 6.4 more fatalities than in the same period last year.
But it added that the rate of fatalities in the first half of this year was up.
The board did not break out the numbers of fatalities by type of vehicle.
The data, it said, is based on data collected from more than 400 transportation organizations and the National Transportation Institute.
Transport organizations are the largest employers in the country and the most important employer of workers in the U.s. government, the report said.
The increase in fatalities came despite the fact that the board reported that there were 9,700 fewer workers in 2015 than in 2014.
But some experts said the numbers do not tell the whole story.
“This is the largest increase in the last 10 years,” said Robert Lipski, the president of the National Association of Transportation Administrators.
“It’s also the largest year of increase in any single year in the history of transportation.”
Lipski said there is still much to be learned about the causes of the increase in deaths and the types of injuries.
The number of workers who were injured in a crash increased more than 20 percent from 2014 to 2015, the study found.
The number of people who died in crashes increased even more, from 4,721 to 5,766, the National Safety Council found.
The increase in injury deaths is the second-highest since 1999.
The last time there was a record was the early 1990s, the government said.
There were 9.6 million workplace fatalities in 2015, up from 8.4 million in 2014, the NTSB said.
That number was a 1.6 percent increase from the year before, which also marked the first year of a nationwide reduction in deaths.
The NTSB did not say how many of the workers were in the truckers, drivers or passengers categories.
The study also found that injuries related to transportation accidents are rising, with 8.2 million workers in workplace accidents, up 12.5 percent from the 7.2 percent increase in 2014 and the 11.1 percent increase last year, the agency said.
