Safety is about preventing the creation of harmful states which may lead to injury or loss of life or unintentional environmental damage. Incidents can arise as a result of human error, environmental factors, physical or system issues, or a combination of these. However, the design of systems and the extent which it takes into consideration relevant environmental factors can impact of the occurrence of human errors.
In the case of road infrastructure, the manner in which the highway is managed and the way it relates to, and makes sense in light of, the environment by which it is surrounded, makes unsafe actions performed by road users more or less likely. Its condition can assist or hinder the user, and its infrastructure can increase or decrease the severity of the outcome when an incident occurs.
We can help with developing holistic safety measures which take into consideration behavioural, environmental and system factors.
