Potential safety benefits associated with speed limit compliance in San Francisco and phoenix

Using novel data from an ADS-equipped vehicle fleet to estimate the travel speed distribution of both the current human driven and a speed compliant fleet, in conjunction with the Elvik speed framework, this study estimated a 30% reduction in fatalities on surface streets in two U.S. cities, highlighting the impact of speed limit compliance on fatality prevention for all road users and building on the existing body of traffic safety literature capturing the deleterious effects of speeding.
