The NHTSA released early estimates of motor vehicle traffic fatalities in 2015 today and the news is not good. This looks only at fatalities involving a car, so it doesn't count single bike crashes or crashes with pedestrians, trains or other cyclists. Other fatalities are not included as well. Still,
Analysis to generate gross estimates of changes reveals significant increases in motorcyclist and nonoccupant (pedestrian and pedalcyclist) deaths for the Nation in 2015 as compared to 2014.
Estimates based on the data coded thus far into FARS for 2015 reveals that most of the Nation saw significant increases in motorcyclist (9% increase), pedestrian (10% increase) and pedalcyclist fatalities (13% increase). Fatalities to drivers and passengers also increased (6% and 7%, respectively)
They don't give a number, but since there were 726 pedalcyclist fatalities in 2014, 13% more would be 820, making last year the most deadly for cyclists since 1995. While fatalities have been increasing somewhat steadily for the last few years, so has the number of people biking and at a faster rate. Meaning that fatalities as a percentage of bike commuters has been dropping since 2005. But unless there is an unprecedented rise in bike commuters this year, it looks like the trend is going up this year.
