Review of Road Safety Theories

Many researchers have investigated road safety and its contributing factors from different aspects, such as economics, engineering and public health, including the design of vehicles and roads, care and treatment of victims in crashes, and enforcement of traffic safety legislation. In order to reduce crashes we need to understand road safety theories. These theories are: engineering, economic, public health, physiological and risk compensation theories. Study of these theories showed that motorization is strongly correlated with income as the rate of motorization is higher in the developed countries with a comparatively high level of per capita economics. It has been found that crashes decreased in the countries with higher economics. On the other hand, implementation of an organized trauma care system will considerably reduce traffic fatalities. Driver fatigue and drowsiness are also related to traffic occurrence, as indicated by the physiological theory of road safety, whereas, technology is not always used for safety but also used as incentives for safety and health.
