Innovative methodology to maintain the nighttime visibility of road traffic signs as part of an integrated approach for road safety

Improving road safety is a key element of road networks management. Any organization in charge of the management and operation of road networks should be able to diagnose problems related to drivers safety. Mobile inspection systems for horizontal road markings are established since decades and support road authorities in their aim to maintain minimum visibility levels and road safety. Similar mobile systems for the assessment of vertical traffic sign conditions are not available, or only in embryonic stage. To date, the inspection and measure of vertical traffic signs is done with handheld equipment (retroreflectometers), which limits their use to a few number of signs in a certain stretch of road. This paper discusses the development and features of the "VISUALIZE‟ system as a solution to the traffic sign inspection process focused on visibility and the safety of drivers. It is a tool that allows us to know the traffic sign condition, in respect to the corresponding traffic code or regulation. The system is a dynamic inspection method for traffic signs, which can perform inspection tasks from a moving vehicle at normal driving speed by using computer vision techniques. First it will provide a better knowledge about sign condition in the complete road network, second it will improve safety planning and decision making.
