A conceptual framework for development of safety performance functions for rural roads in Indonesia

Abstract

Road safety policies provide important guidance for actions to enhance road safety, but often absence an extensive conceptual framework, system theory, and evidence-based study and practice. One effort to enhance road safety is to decrease the number of road accidents. By knowing the accident data at a location, transportation planners can conduct analysis so that they can provide recommendations for improving road safety. However, the prediction model in Indonesia in some studies is more local purposes. Meanwhile, the prediction model used in various countries needs to be adapted to the conditions of Indonesia. The objective of this paper is to integrate all components that contribute to accidents. The work identifies tools that are most and least widely used for components. This framework also provides guidance for developing safety performance functions, what the model is like, what the variables are and what conditions need to be considered according to Indonesian conditions. It is expected that the developed framework can be applied to improve the development of safety performance functions for rural roads in Indonesia.
