C12: Roadway Surface Conditions

Definition:

The roadway surface condition at the time and place of a crash.

(From a State Police Instruction Manual): The intent of this data element is to best describe the condition of the roadway at the crash scene. It should be coded WITHOUT regard to whether or not road surface conditions contributed to causing the crash.

Element Attributes

(From a State Police Instruction Manual): if the code "Other" is used it is recommended that it be explained in the narrative.

Note that the attributes recorded in Roadway Surface Condition in most cases should work in conjunction with Weather Conditions (C10) to describe the crash environment.

Rationale:

Important to identify and correct high wet-surface crash locations and provide information for setting coefficient of pavement friction standards. Critical for prevention programs and engineering evaluations.
