Deployment of intelligent advanced stop warning signs in New Zealand

Each year, hundreds of crashes occur where a driver fails to notice a priority-controlled intersection and drives through without stopping. In the Selwyn District of New Zealand, this problem is particularly prevalent due to the flat, straight roads which intersect regularly across the district. To counter this issue, a new intelligent stop sign has been trialed which warns drivers of the approaching intersection via flashing lights as they approach the intersection. The trial was successful, so a nationwide analysis was conducted which identified 50 sites where this technology may prevent crashes and save lives.
