A new smart highway technology trial will begin in the Upper Hunter to improve safety at a busy rural intersection.
The Rural Intersection Speed Zone (RISZ) system will be trialled at the intersection of Ulan Road and the Golden Highway near Cassilis, between Merriwa and Dunedoo. It will be the first trial of its kind in New South Wales.
The system uses radar technology to detect vehicles approaching the intersection on Ulan Road. When a vehicle is detected, the system will temporarily reduce the speed limit on the Golden Highway using electronic speed signs.
The lower speed limit will create safer gaps in traffic. This will give drivers more time to respond and help larger vehicles, including trucks and other slow-moving vehicles, enter the highway more safely.
The technology is designed for rural intersections where permanent speed reductions may not be needed. It aims to reduce the risk and severity of crashes while keeping major roads efficient.
The fully self-contained system uses solar power and combines vehicle detection, variable speed signs, communication technology, and remote monitoring. It is controlled through a central management system.
The technology was designed and built in New South Wales. Similar systems are already used in other states, but this will be the first trial in NSW.
The 12-month trial is expected to begin in early August. It is part of the Smarter Highways program, which uses new technology to improve road safety, reliability, and network performance across regional NSW.
The trial will focus on using technology to address common safety risks and improve conditions for drivers, freight operators, and local communities.
