Abstract

Safety Analyst (SA) is a set of software tools that can be used by state and local highway agencies for highway safety management. It includes a set of tools to implement the procedures that will be presented in Parts IV and V of the forthcoming Highway Safety Manual. These tools include: a Network Screening Tool, a Diagnosis Tool, a Countermeasure Selection Tool, an Economic Appraisal Tool, a Priority Ranking tool, and an Evaluation tool. By using these tools, Safety Analyst can automate procedures that are now performed manually by highway agencies. FDOT maintains a very large crash database called Crash Analysis Reporting (CAR) System. The database was originally generated by merging crash data from the Department of Highway Safety and Motor Vehicles (DHSMV) with roadway information from FDOT. The database is updated yearly. All reported crashes with a fatality, an injury, and high property damage occurred on state roads are included in this database. The database basically contains all the information recorded in the long form crash report. This project report mainly presents a method to convert all information being stored in CAR system to a format that can be used by SA. In addition, a program interface is developed, basing on this method, to transfer CAR variables and codes into SA variables and codes automatically. Besides CAR system, information in other databases is also used to meet SA requirements, such as Roadway Characteristics Inventory (RCI) database. The program interface has been tested for its validity, reliability, stability and etc. Also, several crash examples are implemented integrally by SA, which are converted from CAR and other databases.
