Appendix A. Intersections with Multiple Countermeasure Considerations

Note to the Reader: Table 36 provides a partial example of the listing of State rural stop-controlled intersections with multiple countermeasure considerations. It shows the number of crashes above the given threshold for a specific countermeasure by intersection. It is created by combining all of the distributions of crashes by intersection, using only those intersections where the number of crashes exceeds the threshold for that given countermeasure. Tables such as these should be prepared for the following types of intersections:

  • State Rural Stop-Controlled Intersections.
  • State Urban Stop-Controlled Intersections.
  • Local Rural Stop-Controlled Intersections.
  • Local Urban Stop-Controlled Intersections.
  • State Rural Signalized Intersections.
  • State Urban Signalized Intersections.
  • Local Rural Signalized Intersections.
  • Local Urban Signalized Intersections.
