5 Investment Projects for Better Road Safety in Chile: Positive Effects on the Generalized Cost of Accidents

This paper evaluates and compares the cost of accidents before and after the execution of 5 investment projects in road safety elements, implemented in central Chile (South America). The projects include the installation of road signs, road markings and guardrails, covering five roads located near the center of the country, in an area with temperate climate (winters are rainy and cool; summers are dry and hot). The roads are bi-directional (two lanes with opposite traffic) and cover terrain that is relatively flat, with some areas of more pronounced vertical and horizontal curves. The average investment is close to USD 10,000 per kilometer. Comparison of the projects’ effectiveness to reduce traffic accidents and their consequences is based on quantitative parameters, focusing on the economic value of accidents’ consequences. Furthermore, the comparison uses indices associated with the roads, the traffic flowing through them and other normalized descriptors based on the roads’ physical and operational characteristics. The main focus is on calculating and presenting the amount of economical savings due to reductions in accidents’ consequences.
