AN EVALUATION OF ACCIDENT SURROGATES FOR SAFETY ANALYSIS OF RURAL HIGHWAYS. FINAL REPORT. VOLUME III. APPENDIXES

The objective of this study was to validate the use of accident surrogate measures for analyzing safety on rural highways. Emphasized were inexpensive, quickly obtained measures. They were tested for isolated horizontal curves and unsignalized intersections on two lane state highways. This volume contains eight appendixes which supplement information presented in summary form in the technical report. Appendixes A through E provide data collection details including the data forms, equipment, the training manual and training program, and accident data collection. Appendixes F and G contain the algorithms used to derive selected surrogate measures and the results of the regression analyses. Appendix H presents a synopsis of the problems encountered when operational variables were collected at night.

• Supplemental Notes:
  • This volume is the third in a series. The other volumes are Volume I - FHWA-RD-86-127 - Executive Summary and Volume II - FHWA-RD-86-128 - Technical Report.
