I feel just by putting boards with some statistics written on it wont really appeal everyone around it, to read it. What needed is something which can really catch his or hers sight. For example one of the most heartening photo ever clicked of a small destitude boy in the barren desert searching for food while a eagle is sighing at it from behind, to make the boy its diet for the day. If we could picturize few accidents that have occured at the site and which can bring some definite appeal in it, it will definitely catch the sight of a human being. So though getting boards and govt approval is a difficult task but still I feel this kinds of appealing sign boards can definitely help to reduce these accidents to some extent.
