Road Safety Audit (RSA)IntroductionIn the past, the Bureau of Transportation Safety and Technology conducted traffic studies from a reactive position, reviewing only a specific location of concern based on a request. While this process worked, it was not efficient and hindered the bureau from effectively addressing the entire state highway system. In an attempt to provide a more comprehensive and thorough review, and to immediately attend to locations which may require safety improvements, the bureau began conducting countywide road safety audits (RSA). RSAA RSA is a proactive and thorough process to complete a traffic study of the Kansas state highway system county by county. The purpose of the RSA is to give the Kansas Department of Transportation (KDOT) an effective and powerful tool to actively recognize and immediately attend to locations which may need safety improvements. The audit is broken down into three phases: office review, field review, and report. Office ReviewThe office review phase consists of analyzing the crashes along all state routes in a county. This includes the Kansas routes, the United States routes, and the Interstate routes (excluding the Turnpike). The crash analysis can help reveal high crash locations and definable crash patterns which may be corrected through changes in roadway geometry or the use of traffic control devices. The office review phase also entails soliciting information from the county, cities, and local KDOT personnel regarding locations of concern, as well as reviewing video-log, past traffic study files, and traffic control resolutions. Field ReviewIn the field review phase, an engineer drives the state highway system in the county. The engineer will observe and record information on a variety of trafficrelated categories including roadway characteristics, geometry, railroads, speed limits, sight distance, pavement markings, signing, and other traffic control devices. The engineer may visit with city officials, county officials, and KDOT district/area personnel to gain insight on locations to be reviewed and to answer any questions. ReportOnce the field review is complete, necessary traffic field data (traffic counts, speed data, school data, etc.) will be obtained. The data will be analyzed, and presented in a final report along with recommendations. The report is sent to the county, cities, and KDOT offices both for information and the implementation of recommendations. ScheduleThe Bureau of Transportation Safety and Technology is in the process of reviewing all counties. After the state is completely reviewed, the bureau will continue to do RSAs with the goal being to complete follow-up reviews every five years. Requests for Specific Traffic StudiesWhen a study request is received, an engineer reviews the location on video-log or on site, and analyzes the crash history. If the crash rate is above average, or if an unusual condition exists, a traffic study is initiated for the spot location. If not, the request is kept on file until a RSA for that county is started. BenefitsA well-managed road safety audit program can have many positive effects:
