Abstract
:By virtue of their variability, mass and speed have important roles in transferring energies during a crash incidence (kinetic energy). The sum of kinetic energy is important in determining an injury severity and that is equal to one half of the vehicle mass multiplied by the square of the vehicle speed. To meet the Vision Zero policy (a traffic safety policy) prevention activities should be focused on vehicle speed management. Understanding the role of kinetic energy will help to develop measures to reduce the generation, distribution, and effects of this energy during a road traffic crash. Road traffic injury preventive activities necessitate Kinetic energy management to improve road user safety.
Highlights
I n the concept of road traffic injury (RTI), mass and speed are properties of all the energy that can be transferred during a crash; and the two properties are connected to kinetic energy
This means that the kinetic energy during a collision greatly increases due to velocity rather than mass and small increases in vehicle speed will result in major increases in the risk of injury.[2]
Despite speed playing the most critical role in RTIs, the extent of bodily injury, depends on the shape of the objects involved and their rigidity as well as on what safety equipment is available.[2]. This is why kinetic energy management needs to focus more on speed, which can be an important implication in RTIs prevention
Summary
I n the concept of road traffic injury (RTI), mass and speed are properties of all the energy that can be transferred during a crash; and the two properties are connected to kinetic (mechanical) energy. Despite speed playing the most critical role in RTIs, the extent of bodily injury, depends on the shape of the objects involved and their rigidity as well as on what safety equipment is available.[2] This is why kinetic energy management needs to focus more on speed, which can be an important implication in RTIs prevention.
