Abstract:

This study developed a comprehensive database system to provide data to multiple traffic safety applications with focus on Safety Analyst. A number of data management tools were developed to extract, collect, transform, integrate, and load the data. In addition, the proposed system includes consistency-checking capabilities to ensure the adequate insertion and update of data into the database. This system focused on data from roadways, ramps, intersections, and traffic characteristics data for Safety Analyst; it was developed to evaluate Clark County, the largest county in Nevada including the cities of Las Vegas, Henderson, Boulder City, and North Las Vegas. The database was used to identify the sites with potential for safety improvements based on various analyses. This study specifically examined the results from two case studies. The first case identified sites with potential for safety improvements with respect to fatal and all injury crashes, specifically regarding intersections; it included all roadways elements, and used default and calibrated Safety Performance Functions (SPFs). The second case study identified sites having a potential for safety improvements with respect to fatal and all injury crashes, specifically regarding intersections; it used default and calibrated SPFs as well. Conclusions were developed for the calibration of safety performance functions and the classification of site subtypes. Guidelines were provided about the selection of a particular network screening type or performance measure for network screening. In general, this study addressed barriers associated with the use of Safety Analyst.
