Way geometry and cross-sectional design, roadside and area features, traffic control, and more Types.â The approach âsupplements and complements traditional site analysisâ and proactivelyĪddresses locations that exhibit high-crash potential due to location attributes such as road. Mented improvements based on high risk roadway features correlated with specific severe crash Safety, as described in the Systemic Tool, is an âapproach to safety involves widely imple. The systemic safety management approach to traffic The Systemic Tool does not actually include any software components, but recentlyįHWA developed a tool that can be used to generate crash tree diagrams based on FARS or To support implementation of the systemic safety management approach to highway safety,įHWA published the Systemic Safety Project Selection Tool (Preston et al., 2013) guidanceĭocument to outline the systemic safety process and to support agency implementation of theĪpproach.

While describing the variousĪpplications of the systemic safety management approaches, data requirements are described Â¢ Application of the usRAP methodology, using the associated ViDA software.Įach of the three approaches is described in more detail below. Â¢ Application of SPFs, using in-house tools or Safety Analyst.

Â¢ Application of the FHWA Systemic Tool methodology, customized to local data availability This section describes three primaryĪpproaches that agencies have used to implement systemic safety management: Differences in crash data availability, roadwayĬharacteristic inventory availability, and scope of the systemic safety program may affect howĪn agency applies a systemic safety management approach. The general purpose and methodology for performing a systemic safety management analysisĪre explained in part 2.3 in Section 2, but agencies use a variety of implementation approachesįor their systemic safety management programs.
