Junction Warning System

Targeting the most dangerous parts of the network will yield the biggest improvement in making roads safer for users. Junctions are one such dangerous area and improvements in junction safety can result in a significant drop in accidents.

Our junction warning system uses intelligent vehicle activated signs (VAS) to alert drivers to vehicles waiting turn onto the carriageway. Using vehicle detection technology, we determine when a vehicle is waiting to turn and, only then, activate the warning sign. Such dynamic signage is more effective than static warning signs, which regular drivers of the route will fail to notice over time.

Efficient use of the same intelligent VAS will improve junction safety further by presenting speeding drivers with a slow down message when there isn’t a vehicle waiting to turn. The threshold for triggering the slow down message can even be tailored to the vehicle class and the associated speed limit.
