The Safety Analysis application helps users produce Highway Safety Manual (HSM) powered benefit-cost calculations in seconds. Safety Analysis helps organizations calculate how each dollar spent on countermeasures affects the specified crashes, and helps allocate safety funds with maximum effectiveness. The Safety Analysis application has 4 key features: Recommendations, Applying Treatments, Project Overview, and Reports.

Note - The Safety Analysis - Intersections Application is sold separately from the Safety Analysis - Segments Application. To find out more about Safety Analysis - Intersections, please contact your Numetric representative.

Safety Analysis - Route/Intersection Selection and analysis
