1. (a)

   1. (1) Crash data for an appropriate safety analysis as part of the IJR should include at least the three (3) most recent years data is available.
   2. (2) The proposing entity should request this data from the Arkansas Department of Transportation.

2. (b) The type of information that is typically relevant to the safety analysis includes:

   1. (1) Crash location;
   2. (2) Crash frequency;
   3. (3) Crash type;
   4. (4) Crash severity;
   5. (5) Work zone related;
   6. (6) Time of day; and

3. (c)

   1. (1) Currently, crash data on nonstate highways in Arkansas is normally not locatable in the crash database.
   2. (2) There is currently a statewide effort through the Division of Arkansas State Police to require the location coding of crashes on functionally classified nonstate highways.
   3. (3) Once this effort is complete, crashes on nonstate highways within the safety influence area of interchanges should be locatable.
   4. (4) Until then, if the crossroad or frontage road is a nonstate highway or not maintained by the department, reliable and useful crash data may not be available.
