SYDNEY, AUSTRALA - Artificial intelligence that automatically detects threatening behavior at train stations is part of a new trial to improve safety for women traveling at night in Australia. The New South Wales state government says nine out of 10 Australian women have experienced harassment on the street. It asked researchers to submit ideas to improve safety as part of its Safety After Dark Innovation Challenge. Four entries have been chosen and will be tested over the next six months. One group from the University of Wollongong will develop artificial intelligence (A.I.) software that will examine real-time feeds from security cameras and alert an operator when it detects suspicious activity or an unsafe environment.
