A Safe System approach to speed would involve setting appropriate limits, enforcing those limits consistently, implementing new vehicle technology and modifying our road infrastructure.
First, adjusting speed limits to prioritize safety. We can focus on preventing injury to all road users, including pedestrians and cyclists. Second, enforcement to give teeth to those limits. Speed cameras are a proven strategy for this and can minimize encounters between police and violators.
Third, vehicle technology. Many commercial fleets in the U.S. have speed limiters. But technology that prevents or discourages speeding has yet to be widely adopted in private passenger vehicles. Finally, traffic-calming solutions such as narrowing lanes, reducing their number or installing speed humps can coax drivers into easing off the gas pedal.
