The Flooded Roads Smart Warning System (FRSWS) project uses smart technology to provide both proactive and reactive mechaims to enhance road safety during flood episodes. The FRSWS minimises the risk of drivers inadvertantly driving into flooded roads by using advance warning signs that only activate in flood conditions. The innovative design and programming of these signs allows real time mapping and information for each road location with a FRSWS to be provided to disaster management entities and the community through a range of communication methods. Data collected from activation of FRSWS signs is integrated into open data platforms to support planning and design considersations for both roads and flood modelling.
