Best Practices for Road Weather Management Version 2.0
Reunion Island's Merlin Project: An ITS Implementation Success Story
In response to rock falls triggered by torrential rains and high winds over a 13 km coastal road on Reunion Island (a French territory) in the Indian Ocean, traffic managers use automatic lane closure barriers on lanes near cliff and movable barriers to delineate travel lanes on remainder of road. From the TCC, they collect traffic and weather data and disseminate information via VMS. This technique increases safety by separating opposing traffic flows, reducing speed limits, and reducing incident response times.
