Abstract

Traffic accidents are one of the leading causes of life loss in Europe. Inappropriate or excessive speed is one of the largest contributors to traffic accidents and has a stronger effect on injury severity than almost any other known risk factor. This paper evaluates the possibility of inducing a substantial speed reduction in a hazardous section using perceptual countermeasures to improve safety via a low-cost solution. To validate the solution, the proposed methodology was applied to a road in northern Spain with a significant number of accidents per km including traffic volume effects (a black spot). This paper describes the proposed solution and presents the results, which show that a low-cost solution can reduce traffic speed and accidents.
