COMPUTER PROGRAMS FOR SAFETY ANALYSIS. FINAL REPORT

This report summarizes the results of a study to assess the needs of transportation agencies for computer software to aid in the analysis of accident data. Two computer programs were developed to meet the identified needs of local (city, county, regional) transportation agencies. The programs will operate on microcomputers and are user friendly, thus requiring minimal user training. The first program, "Highway Safety Analysis and Monitoring" (HISAM), is used to enter, edit, and maintain accident records, street inventory data, and traffic volume data. It also contains subroutines for identifying high-accident locations, analyzing accident characteristics, and producing standard accident analysis reports. The second program, "Highway Safety Evaluation" (HISAFE), is used to perform safety evaluations of completed safety projects. The program contains subroutines to aid the user in selecting the appropriate experimental design for the evaluation, computing the accident rates and percent changes resulting from the safety improvements being evaluated, performing statistical significance testing, and conducting an economic evaluation of the effects of the safety improvement. These programs are fully documented in their respective Users Manuals and Operators Guides.
