Intelligent Transportation Systems (ITS) have offered a real benefit to the security, safety and communications management of road tunnel infrastructure, acting as an ‘all-seeing eye’. The systems inside the tunnels, can include management, traffic data, speed enforcement, emergency phones, Closed Circuit Television, Automatic Incident Detection, Public Address and Radio Rebroadcast. Outside of these, tunnel systems can include advanced traveller information, barrier gates, Over Height Vehicle Detection, Hazardous Goods Vehicle Detection and Hot Vehicle Detection.
The main objective of these systems is to provide support to the operations of the tunnel and contribute to an integrated, safe, responsible and sustainable transport system and an overall good experience for drivers.
Here, Nitin Wazir, WSP’s Intelligent Transport Executive for NSW, discusses the elements ITS technology that should be considered mission-critical for road tunnels.
He says, “ITS – not only aids with the efficient operations of our road network – but it also enables us to detect incidents earlier, helping to save lives and minimise infrastructure damage.
“For tunnel incidents, time is even more critical as the space is more confined and subject to greater smoke and fire hazards, as well as increased periods of traffic congestion resulting from incidents.
“Because this information is so valuable, tunnel ITS must be resilient to failure and achieve a high degree of full system availability.”
