Knowra Road safety Road safety Road safety is the prevention of road crashes and the reduction of death and injury when crashes occur. It combines measures addressing roads, vehicles, speeds, road users, and emergency response.
Safe System approach : A road-safety framework that assumes people make mistakes and designs the transport system to prevent fatal and serious injuries. It organizes road safety around shared responsibility and layers of protection.
Road traffic injury prevention : Measures that prevent injuries and deaths caused by crashes involving road users. It focuses road-safety practice on reducing the human toll of crashes.
Vision Zero : A road-safety policy framework that aims to eliminate deaths and serious injuries in road transport. It applies the principle that preventable traffic deaths are unacceptable.
Road traffic collision : An event involving a moving vehicle on a road that results in injury, death, or property damage. Crashes are the events that road-safety measures seek to prevent or mitigate.
Traffic flow : The movement of vehicles through a road network, often measured by speed, volume, and delay. Optimizing vehicle movement can conflict with reducing speeds and crash severity.
Speed management : Policies and measures that set, enforce, and encourage safe travel speeds. Speed affects both the likelihood of a crash and the severity of its injuries.
Drink-driving : Operating a vehicle after consuming alcohol, which can impair judgment, coordination, and reaction time. Preventing alcohol-impaired driving addresses a major source of crash risk.
Sweden's Vision Zero : Sweden's national road-safety policy, adopted in 1997, that makes eliminating road deaths and serious injuries its long-term goal. Its adoption helped establish Vision Zero as a practical policy model.
Vulnerable road user : A road user, such as a pedestrian or cyclist, who lacks the protection of an enclosed vehicle. Unequal physical protection makes these groups especially exposed to severe injury.
Road capacity : The maximum rate at which a road or transport facility can carry traffic under specified conditions. Capacity expansion can increase exposure and complicate safety goals.
