What is the Road Safety Calculator
The Road Safety Calculator is a tool for road safety policymakers to make an informed decision on planning road safety investments. Currently, the Calculator tool incorporates interventions covering all pillars of road safety (except Vehicle Safety) and helps decision-makers select the most effective road safety strategies for the road safety issues faced by their countries. For this purpose, road crash deaths and injury profiles are used along with Crash Modification Factors derived through systematic reviews. The Calculator allows users to input basic information on current road safety status, road use and behavior status etc. The output from this tool provides estimates of benefits in terms of reductions in deaths and serious injuries, given a road safety intervention is selected and implemented.
This version of Road Safety Calculator covers 10 road safety intervention areas:
- Increase Helmet Use with [strict] enforcement
- Increase Seatbelt Use with [strict] enforcement
- Reduce alcohol-involved casualties
- Install sidewalks along both sides of urban arterial corridors
- Convert uncontrolled intersections to controlled
- Provide comprehensive centerline crossover protection on two-lane high speed roads
- Provide comprehensive run-off-road protection (clear zones and barriers) on high speed roadways
- Reduce speed limits and increase enforcement on high speed roads
- Implement traffic calming treatments on residential collector streets
- Improve post-crash emergency care services.
