The Safety Highway Geometry Based on Unbalanced Centripetal Acceleration
Road accidents take a significant part in the human lives losses and financial resources in worldwide sense. In order to devise new strategies to combat this problem there is a continuous search for new approaches from researchers, dealers and government agencies. Recent changes in the Brazilian traffic code, such as the increase of the score limit on the driver qualification and the restrictions on speed enforcement, imposed a new operational scenario. Speeding should increase and, consequently, reflecting more accidents and severity. A proposed model in this work has several equations, correlating road geometry parameters and accident record indexes. This model can be applied as an objective policy tool of physical improvements and speed reduction focusing on accident severity and amount. It was taken the unbalanced centripetal acceleration on horizontal curves as the main derived term, generated mainly by excess of speed in relation to the allowed one, under the Physics and human restrictions criteria. There were selected some Brazilian road segments to apply this model, conceiving specific equations and evaluating confidence under determination coefficient, that resulted a good level to the selected place.
