Towards a risk assessment model for the road traffic environment

De Vries, ID, Kockott, SR 29 April 2010 (has links)
After World War II, which lasted from 1939 to 1945, the economies of many countries worldwide experienced a boom period. Many people were able to buy private motor vehicles. A consequence of this, however, was that the number of road traffic accidents in these countries has also increased dramatically. From reports over decades it became clear that traffic safety programs that were implemented did not have the desired effect. To evaluate success, countries normally used accident rates or indices based on mathematical formulas. Rates and indices were and are still used to compare accident situations among countries – normally on an annual basis. It seems that motorised countries try to determine a “winner” by recording the lowest accident rates and indices in a specific year. The approaches followed are uncoordinated. In addition to trend analysis, the municipal police managers or road transport and traffic safety fraternity authorities in the various countries could also focus on risk analysis. Risk analysis is used in the industry with its many role players and security and safety can be promoted through this approach in a more scientific manner. Although risks are normally formulated in terms of probability theory, a Risk Score Value model could be of further benefit to road traffic managers. The Risk Score Value could be used to assist authorities to conduct cost effectiveness studies and to prioritize and optimise countermeasures in a holistic integrated manner with a view to reduce road operation risks to an acceptable level.

Road Traffic Safety Problem Based Learning Module

David, Iuliana January 2008 (has links)
Road traffic safety has increasingly become in need of educated road safety professionals, as the number of accidents in the World Health Organization member countries exceeds one million. The profession itself is transitioning from experience based decision making to empirical, theoretical and mathematical based solutions. However, road traffic safety is a multidiscipline, crossing over many fields and requiring a high degree of communication between different institutions. There are very few institutions that provide programs in the field; furthermore, they employ traditional lecture-based teaching methods. The traditional teaching environment does not fulfill the educational needs of future traffic safety professionals due to its rigidity and lack of problem solving exercises. An alternative method, namely problem based learning, is recommended as an alternative teaching method in this paper. The thesis is constructed in such a way as to develop a complete road traffic safety educational module at graduate and post graduate level. The theoretical basis on which a road traffic safety module is later built is presented in the first part of the thesis. Major concepts in road traffic safety, as well as problem based learning methods are investigated. In addition, a literature review SWOT analysis based on literature is conducted.The module development consists of establishing the road traffic safety learning goals for each segment in the module, appropriate assessment criteria and group work format. The module contains gradual difficulty level problems, starting from the easiest topic and easiest format (closed ended problem) and ending with the hardest topic and hardest format (open ended problem). The last section employs the SWOT analysis findings in the theoretical section to develop a SWOT analysis of the road traffic safety module presented in the thesis.

Prehospital Staffing and Road Traffic Accidents: Physician Versus Trained Nonphysician Responders

Grant, Timothy A. 01 January 2015 (has links)
Road traffic deaths, which affect people in their productive years, are projected to be the third leading cause of death by the year 2030. While most studies have focused on road infrastructure and vehicle safety, this study examined something new: the impact of prehospital response to road traffic accidents on the rate of death. Some countries send physicians to the scene of an accident; some send paramedics or registered nurses. The question this research sought to answer was whether the use of physician responders resulted in a lower rate of death compared to the use of nonphysician responders. The literature makes it clear that rate of road traffic death is related to country income and governance indicators, so first those variables needed to be equalized. My conceptual framework for this cross-sectional correlation study was the Haddon matrix, which organizes injuries by temporal (pre-event, event, and postevent) and epidemiological (host, agent, and environment) factors. Using World Health Organization data on road traffic injury and country income, World Bank data on governance indicators, and a literature search of 67 countries' prehospital response profiles, significant negative correlations (p > 0.001) were found for road traffic deaths and income, r (65) = -0.68, and governance indicators, r (65) = -0.646. No significant difference in the rate of road traffic death was found between physician and nonphysician prehospital staffing. Because increasing countries' income and improving governance are long-term, ambitious goals for developing countries, training nonphysician prehospital responders appears to be the most effective social change to decrease the burden of road traffic deaths.
