Abstract
Traffic accidents are a serious problem in every society. Traffic safety is a science that analyzes road accidents with material damage, lightly injured, severely injured and killed persons. This paper proposes that road safety investment can be optimised by the development of a road safety management model. Road safety strategies typically include a basket of engineering, enforcement and education/training measures but there does not appear to be any management model which permits the optimisation of road safety investment. The proposed model utilises linear programming to predict changes in road safety resulting from safety interventions. It is mainly based on research in the areas of engineering and enforcement since there is little published research on the correlation between education and accident reduction. The model output provides the accident reduction and associated costs resulting from feasible road safety strategies. This should benefit policy makers when allocating resources. This example will be good experience for Traffic safety management system in the Republic of Macedonia.
Highlights
Traffic safety management is a systemic approach to reducing traffic accidents and the consequences of them
This paper proposes a linear programming technique to assist in the optimization of resources
In the case of road safety management, linear programming is used to maximise the average cost saved by preventing road traffic accidents subject to the implementation costs, geometrical constraints imposed by the road and resource constraints
Summary
Traffic safety management is a systemic approach to reducing traffic accidents and the consequences of them. The positive experiences from the developed countries that have achieved a high level of traffic safety as the draft models for traffic safety management should be used. The three countries with the safest roads in Europe, Sweden, the United Kingdom and the Netherlands, implement comprehensive road safety strategies that involve local authorities, road users, emergency services, enforcement agencies, etc. Such strategies require a management system to optimize road safety levels. The selection of safety performance indicators is discussed Both safety countermeasures and performance indicators are used in a linear programming model
