For example, the chances of survival for an unprotected pedestrian hit by a vehicle diminish rapidly at speeds greater than 30 km/h, whereas for a properly restrained motor vehicle occupant the critical impact speed is 50 km/h (for side impact crashes) and 70 km/h (for head-on crashes). This threshold will vary from crash scenario to crash scenario, depending upon the level of protection offered to the road users involved. The basic strategy of a Safe System approach is to ensure that in the event of a crash, the impact energies remain below the threshold likely to produce either death or serious injury. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, horse riders, and passengers of on-road public transport (mainly buses and trams).īest practices in modern road safety strategy: ![]() Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. ![]() Sacrifices to the Modern Moloch, a 1922 cartoon published in The New York Times, criticizing the apparent acceptance by society of increasing automobile-related fatalities Sidewalks, curbs and traffic signals in Hagerstown, Maryland, United States Speed limits in different areas, unusually with only a "recommended" limit (130 km/h) for the Autobahn DRIP variable message sign guiding traffic on the Dutch A13 motorway Vehicles experiencing a breakdown or an emergency can stop in the emergency lane these lanes may themselves present risks to traffic.
