Game-changing technology to design traffic lights that absorb kinetic energy, stopping them from crumpling when hit by a vehicle, will prevent thousands of fatalities and injuries each year and make our roads much safer. That's the prediction from University of South Australia (uniSA) senior lecturer and research lead Dr Mohammad Uddin, who is partnering with manufacturing company impact Absorbing Systems (lAS) on a new project to minimise collision-related injuries as well as damage to traffic lights and vehicles. The $640,000 project, partially funded by the innovative Manufacturing CRC (iMCRC), will leverage IAS's expertise in road safety and UniSA's engineering design and advanced manufacturing skills to ensure traffic lights absorb a high-impact crash, remain undamaged and operational, and save pedestrian and motorists' lives. The technology involves replicating existing IAS- fabricated energy absorbing bollards and tuning the design to better suit the shape, length and size of common traffic lights, while satisfying regulatory standards. ' Recent statistics show that in Australia, traffic light collisions cost $18.5 million a year in fatalities, $53.7 million for injuries and up to $16 million annually to repair, install and maintain traffic lights," Dr Uddin says. Worldwide, the figure is much higher.

Option 1: "Make our roads safer."

Explanation: The text states that the technology will prevent thousands of fatalities and injuries each year and make our roads much safer. This aligns directly with the main idea of the text, which emphasizes the safety benefits of the new traffic light technology.

Option 2: "The normal operation."

Explanation: The text mentions that the traffic lights will remain operational after absorbing a high-impact crash. This indicates that one of the functions of the technology is to ensure the normal operation of traffic lights even after collisions.

Option 3: "Meet regulatory standards."

Explanation: While the text mentions satisfying regulatory standards, this is not a function of the traffic lights themselves but rather a requirement for their design. Therefore, it does not directly answer the question about the functions of the traffic lights.

Option 4: "Save the lives of pedestrians and drivers."

Explanation: The text explicitly states that the technology aims to save pedestrian and motorists' lives by minimizing collision-related injuries. This is a clear function of the traffic lights that absorb kinetic energy.

Option 5: "Increase collision damage."

Explanation: This option contradicts the main idea of the text, which focuses on reducing damage and injuries. Therefore, it is incorrect as it does not align with the purpose of the new technology.
