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.

This was an investigation into the impact of road traffic collisions in Mafikeng. The study revealed that community members in Mafikeng were aware of the fact that road traffic collisions had a number of impacts on the lives of the public in Mafikeng. These included loss of human life, damage to vehicles, medical costs, travel delays, insurance costs and effects on dependants. Various types of vehicles were involved in these collisions. The respondent community members had the view that the quality of the road in the Mafikeng Local Municipality was the main contributor to road traffic collisions. This was attributed to pot holes on the roads. They were all in favour of introducing Road safety Programmes in the municipality. The study recommends the following: • Accident Report forms should be printed with serial codes in order to create a database of all traffic collision accidents in the local municipality. Currently there are no accurate data. • The use of ICT techniques and facilities should be increased in order to improve efficiency and effectiveness of data capturing and preservation. • There must be uniformity in the soft ware used to capture and preserve data collected. • Road Safety awareness should be introduced in the school system at all levels to build a culture of road safety among the public. • The government programme of Arrive Alive Campaign should not be promoted only during festive season. It must be a campaign conducted throughout the year. / Thesis (MBA) North-West University, Mafikeng Campus, 2010

Road barriers were traffic violations which affects traffic order, safety, and life quality. The behavior of bullying disadvantaged groups via traffic barriers harms human dignity, social justice, and the city's and nation¡¦s image. Although the Traffic Executive Law has reached maturity, road barriers are still all over the place. In order to fully understand these phenomena and come up with right decisions, the social, political, economic, and legal dimensions should be included and studied. Based on theory and practice, this study conducts literature review and data collection and analysis from road barriers removal perspective, especially in Kaohsiung City. According to the basic principles of Traffic Executive Law, the structure of this study is divided into five parts: Establishment Principle, Administrative Organization, Administrative Authority-Limits, Administrative Remedy,and Administrative Supervision. In our diverse and democratic society, the government authority has become more liberal and road barriers cases are endless. To pay attention to people¡¦s opinions and feelings and create the win-win situation, the authority should integrate department¡¦s resources, implement administrative measures efficiently, legally, and rationally. Therefore, the administrative purposes of ¡§people obey the law¡¨ and "Traffic are in an orderly manner and smooth" can be reached.

The principal excitation to a vehicle's chassis system is the road profile. Simulating a vehicle traversing long roads is impractical and a method to produce short roads with given characteristics must be developed. By understanding the characteristics of the road, a reduced set of models can be created from which appropriate representations of the terrain can be synthesized. Understanding the characteristics of the terrain requires the ability to accurately measure the terrain topology. It is only by increasing the fidelity and resolution of terrain topology data that application of these data can be advanced. The first part of this work presents the development of a high fidelity 3-D laser terrain measurement system. The system is developed for both on-highway and off-road measurement. It is capable of measuring terrain in three dimensions, whereas current systems measure separate 2-D profiles in each wheel path of the vehicle. The equipment setup and signal processing techniques are discussed, as well as future improvements and applications of this enabling technology. The second part of this work develops a method of characterizing non-stationary road profile data using ARIMA (Autoregressive Integrated Moving Average) modeling techniques. The first step is to consider the road to be a realization of an underlying stochastic process. The model identification techniques are demonstrated. Statistical techniques are developed and used to examine the distribution of the residual process and the results are demonstrated. The use of the ARIMA model parameters and residual distributions in classifying road profiles is also discussed. By classifying various road profiles according to given model parameters, any synthetic road realized from a given class of model parameters will represent all roads in that set, resulting in a timely and efficient simulation of a vehicle traversing any given type of road. / Master of Science
