Abstract:

SafetyAnalyst is a set of state-of-the-art software tools that integrates all the steps in the roadway safety management process. The software automates the advanced empirical Bayes (EB) analysis procedures, requiring agencies to only need minimum statistical knowledge. Agencies that have implemented SafetyAnalyst have consistently identified converting local data into SafetyAnalyst import files as the most challenging step in deploying the software. This paper summarizes the Florida’s efforts in implementing SafetyAnalyst for its state road network. The SafetyAnalyst application process was first introduced. The process integrates the SafetyAnalyst tools, a data conversion tool developed to automatically generate SafetyAnalyst import files, and a Geographic Information System (GIS) tool used to spatially display high crash locations. The procedure employed to generate SafetyAnalyst import files for the state road network in Florida was then presented. A major effort was to collect the data variables that are required by SafetyAnalyst and are currently unavailable in Florida databases. A second major effort involved the conversion of local attribute codes to the standard codes required by SafetyAnalyst. Moreover, a sizeable amount of roadway network data was assigned to the user-defined Florida-specific site subtypes as the data do not match the SafetyAnalyst’s default subtypes. Another undertaking was to manipulate the roadway network data since Florida data has several unique characteristics that could not be directly accommodated within SafetyAnalyst. The experience documented in this paper should help provide useful information for agencies that have just gotten started with SafetyAnalyst or are contemplating its implementation.
