Like those ground traffic lights would help, people are so focused on their 5'' screen that they won't even notice even if the light flashed constantly. They still walk on and get run over a by a car or train as they're that blind and deaf to their surrounding that nothing will help.
I rather see that money spend on cameras placed on those cross overs so whenever one of those stupid idiots walk through red because he's too busy worrying about the latest twitter feed and gets hit by a car the stupid idiot if he's lucky to even have survived gets charged with the damages inflicted onto the car or in case of a train the therapy costs for the driver who went through such horrible experience!
