It is recommended that safety data is used to complete a safety analysis. Safety data often includes crash records, geometrical features of a roadway facility, proposed safety improvements to a roadway, and roadway characteristics such as ADT. Please see

Section 2.2.1

and

2.2.3

for more information related to collecting geometric data and segment traffic counts. Additional information regarding data collection needs for safety and crash analysis is included in

Chapter 5

and

Chapter 6.

The intent of gathering safety data is to complete a historical or predictive safety analysis that identifies potential locations to improve safety.
