Abstract:

The Highway Safety Analysis and Monitoring (HISAM) software was developed under a Federal Highway Administration research contract and is designed to aid local agencies with data base development and accident analysis. The package of programs is designed to enter, retrieve, process, and analyze traffic accident report data, link description data, and node description data. The City of Charlotte, North Carolina, with a population of 350,000, was chosen as the test site for the developed software. The average 20,000 accidents per year provided an excellent data base with which the software could be tested. By the end of the test phase the City was able to identify high-accident locations based on accident frequencies, accident rates, or EPDO indexes and rates. This paper describes both the data input and the report output of HISAM as well as the City's experience with the software.
