An overview of the pedestrian accident problem in South Africa is given, and the engineering solutions implemented to improve pedestrian safety are discussed. The pedestrian problem accounts for part of the road safety problem in South Africa. In recent years there has been a reduction in the number of pedestrian fatalities and injuries. Research findings in the early 1980s showed that inadequate provision was being made for pedestrians in a country where about 80 percent of all trips were made by public transport and by foot. A comprehensive research program has been conducted since 1980 to upgrade all the facilities through the development of warrants for the provisions and guidelines for the correct layout and siting of the various types of pedestrian facilities. The various operational problems encountered at the different types of pedestrian facilities are discussed to provide a safer environment. These problems and solutions are dealt with according to the various traffic engineering approaches adopted to improve pedestrian safety. First, the methods used to integrate pedestrians with vehicular traffic are highlighted, namely through temporal separation (pedestrian crossings, school patrol crossings, traffic lights) and soft separation (traffic calming measures). Second, the technologies developed to segregate pedestrians from vehicular traffic through horizontal separation (pedestrian malls, township layout, sidewalks) and vertical separation (foot bridges and subways) are discussed. Other aspects are pedestrian facilities on rural roads, pedestrian signs and markings, and facilities for disabled pedestrians. Apart from the dissemination to practitioners of individual research reports on pedestrian facilities produced since 1980, the warrants and guidelines developed since 1980 were incorporated into a pedestrian facility manual published in 1993. Technology transfer workshops were conducted throughout South Africa to train road authorities and consulting engineers on use of the manual. It is concluded that the implementation of these warrants and guidelines since the mid-1980s together with a holistic traffic safety management plan have contributed to the reduction in pedestrian fatalities and injuries since 1989.

Because the current research on traffic level has not yet been achieved classification, it cannot timely and effectively provide the basis for the public transportation and safety management of the traffic control department. Introduce traffic safety index based on toll data to evaluate freeway traffic levels. Firstly, combined with the relevant indicators of traffic engineering, put forward the concept of freeway traffic safety index; secondly, calculate the traffic safety index by analyzing real-time toll data; finally, in order to improve the accuracy of evaluation, have an optimization of traffic safety index definition. Application on the Beijing-Hong Kong-Macao freeway shows that traffic safety index can be combined with monitoring data to evaluate the condition of road sections and the road network, and its historical data can be used to predict the road traffic conditions, and provide effective guidance for freeway traffic safety operation.

Worldwide anthropogenic changes influence complex aviation-wildlife relationships. Wildlife Hazard Management (WHM) should include nature conservation. The number of bird strikes continuously increases parallel to growth of air traffic and airport infrastructure. In Poland, ca. 200 bird species have been recorded at aerodromes of which some 30 are considered hazardous to aviation. Analysis of wildlife hazard to aviation should be a part of the preliminary documentation for planned aerodromes. Identification and bird strike risk assessment allow preparation of Wildlife Hazard Management plan which includes pro- and reactive mitigation measures. The measures should consider the most up-to-date available WHM tools, including available radar systems. Operational manuals should include the Wildlife Hazard Management as their inherent part already in the planning phase. This requires systemic and interdisciplinary cooperation both at the airport level and at the level of national air traffic safety management. It should include state authorities but also non-governmental organizations involved in nature protection.

Beneficial Uses

In South Africa the ultimate goal in water quality management is to keep the water resources suitable for all “beneficial uses”. Beneficial uses provides a basis for the derivation of water quality guidelines, which, for South Africa, are defined in Water quality guidelines for the South African coastal zone (DWAF, 1991). The CSIR has developed a practical approach to marine water quality management, taking into account international trends and local experience, which can be applied to any coastal development with potential influence on water quality. The management plan is divided into three logical components, i.e. • site-specific statutory requirements and environmental objectives; • system design with specific reference to influences on water quality; and • monitoring programmes. Within this management approach water quality issues are addressed in a holistic manner, through focused procedures and clear identification of information requirements. This paper describes the procedures and information requirements within each component of the water quality management plan, with specific reference to marine disposal systems. Ideally, the management plan should be implemented from the feasibility and conceptual design phase of a development and the timing of the different procedures within the development process are therefore also highlighted. However, the logical lay-out of procedures allows for easy initiation (even to existing disposal system) at any stage of development.

The analysis of national data on the number of deaths showed that in Poland from 2010 to 2016 it was possible to reduce the number of fatalities by about 22%. The tendency of changes in the number of fatalities, however, is not homogeneous. When data of individual voivodships is analyzed, the situation is different. The largest reduction in fatalities in the analyzed period of time concerned voivodship Świętokrzyskie, where there was more than 45% drop in the number of fatalities. The following voivodships: Łódzkie, Lubelskie and Podkarpackie recorded a decrease in over 30% of fatalities. Unfortunately, at the end of the classification there were four voivodships with a fall below 8%, and what is disturbing voivodship Lubuskie recorded a nearly 5% increase in the number of fatalities. The current traffic safety management at the level of voivodships is often the implementation of central recommendations, which, as results from the analysis of statistical data, are not equally effective in every province. Therefore, models for forecasting changes in road safety are required. Taking into account local characteristics and implemented actions can be used to manage security more effectively at the regional level. This paper presents examples of the use of mathematical models to predict the number of fatalities in individual voivodships depending on the adopted action scenarios. Regression models were developed, taking into account demographic, infrastructural, economic and automotive factors. It turned out that in individual voivodships, various factors affect the level of road safety on roads differently. Therefore, an individual approach to each voivodship is important in order to reliably forecast the level of security.
