Wireless Active Guardrail System for environmental measurements

Abstract

The paper presents the design and implementation of a Wireless Active Guardrail System (WAGS), that adds to the typical passive protection of guardrails the capability of monitoring both traffic and environment along the roads. The general overview of a WAGS, intended to be applied on highways, is presented and the measured quantities are discussed. The architecture of a sensor node for environmental monitoring experimentally validated in laboratory is presented and future improvements and features are suggested.
