Australian taxpayers spent a whopping $34 million last yr to remove graffiti from Sydney’s commuter trains. To struggle this metropolis blight, the Australian Division of Transport is rolling out an digital “nostril” that alerts authorities in precise-time. This technique, dubbed “the mousetrap”, prompts when it detects paint marker and spray-can aerosols. It then immediately engages a closed circuit recording of the crime sooner than alerting the police, who determine up the perp on the next stop. This technique has already undergone viability testing and, in response to CBC Info, has caught 30 vandals pink-handed. Sydney Trains, the federal authorities-owned rail agency that operates the world’s commuter strains, hasn’t disclosed how a lot of the models may be deployed, solely that they are going to be swapped between service strains at random intervals.
