The StoryMapBy The NumbersData

 

HOW WE DID THIS PROJECT
The Sunday Record analyzed fatal crashes on all roads in Ulster, Sullivan and Orange counties as well as the stretch of the Thruway in Rockland County from 1994 to 2005.

While overall trends were drawn from 1994 to 2005 data (see sidebar), the ranking of our most deadly roads was based only on crashes from 2000-2005.

To assess the roads equally, we applied a mathematical formula that accounts for the roads’ varying lengths and traffic volumes.

That formula results in a rate, expressed in crashes per 100 million miles driven. So while a busy road such as Route 17 might have more fatal crashes in total, its rate does not rank in the top tier because its relatively high number of crashes are spread across many, many miles of driving.

Data was drawn from the a reporting system maintained by the National Highway Traffic Safety Administration.

We invite readers to take a deeper look at the data and suggest stories or trends that they might spot.
