Identifying Black Spots Based on Safety Potential - A Suitable Approach to Accident Reduction in Developing Countries

抄録

In improving road safety, identifying black spots based on safety potential is also known as identifying locations with potential saving in accident costs. Such identification is an attempt to make the selection of black spots which are most suitable to treat out of the identified ones. This paper intends to introduce an approach to identifying locations with potential saving in accident costs. In such approach, the key parameter used to assess the safety performance of road spots is the safety potential. This approach enables the identification of the black spots for which safety improvement measures are expected to have the greatest economical effectiveness. As a result, the approach is of great use to accident reduction in developing countries facing limited budgets for road safety improvement.
