Solar Powered Autonomous Emergency Road Signing Waterlogged System in Highways

Abstract

An emergency road signing system is an important device to prevent road disasters, especially during jeopardize conditions. In this project, it is focused on the shallow depth of water from 10cm to 30cm that can slow down the vehicles or even causes the collision. Arduino UNO microcontroller is utilized to detect the waterlogged and shows the of water depth on the road sign to allow the drivers to make a decision ahead for passing through the waterlogged. Furthermore, ZigBee wireless module is used to interface the sensor and display to increase the movability of the display from the waterlogged location. The system is powered up by the PV panel to support green technology and protect the environment as well. From results, it is found that placing the three signboards before the waterlogged location is more effective for drivers to respond.
