Abstract

The objective of this study is to develop a safety analysis system that integrates crash data and roadway related information. This system is developed in a Geographic Information System (GIS) environment. It includes customized user interfaces to support queries to analyze data and to display results either in graphical or tabular formats. The system also affords the capabilities to export such results. The system permits analyses to be performed either at individual locations such as intersections, or for roadway segments. These analyses are based on data fields included in the crash database. The queries may be based on individual attributes recorded in the crash database or by combining multiple attributes from the database. The system also contains a module to identify high crash locations based on methods identified from the published literature. The methods range from those based on simple crash frequency to more complex methods which incorporate different weights for crashed based on the crash outcomes. An application of the system is illustrated using data from the Las Vegas metropolitan are in the state of Nevada; The system can be used to identify safety issues in a region, and to plan and deploy appropriate countermeasures to enhance safety. It also can be used to monitor the effectiveness of traffic safety programs. Such a system could also be used to screen projects and operational strategies to be funded in through appropriate funding processes.
