Abstract

This paper aims to present two sensor node prototypes designed to collect information about roadlevel climate. These prototypes are part of a Wireless Active Guardrail System (WAGS). One node was designed to perform multi-sensor measurements, which can provide information about the road surface state, such as dry, wet or iced. The second node was developed to provide a quantitative estimation of visibility grade in presence of fog. In the paper, the detailed hardware structures, the sensing mechanisms and several on-field tests are described and discussed.
