Methodology: Most Dangerous Intersections in New England 2014

Monday, February 24, 2014

 

To rank the Most Dangerous Intersections in New England, GoLocalProv began with every state's listings of their most dangerous intersections.

Those intersections were defined by each state as to whether they included off-ramp and on-ramp areas on highways as well as traditional four-corner intersections in urban and suburban areas. GoLocal's researchers utilized accident data provided by each state's Department of Transportation, and assessed four factors:

 • Total number of accidents
 • Fatalities
 • Injuries
 • Property damage only

Because states offered lists of varying lengths, GoLocalProv utilized the Top 10 worst intersections from each state for its comparison and ranking.

Different states chose different time spans in which to accumulate their data (3-10 years), therefore GoLocal standardized the tallies to a 3-year sum.

GoLocalProv created a ranking formula that weighted each of the 3 categories of crashes based on the "danger" of the outcome (fatalities were weighted more than injuries, which were weighted more than property damage only), which yielded the final ranking order.
