(sorry, but for some reason I can't post comments [i can't find the submit button], so I'm posting my comment to "Animal Repelling Device" as a new post. if the webmasters read this and can turn it into a comment, please do so.)

I had a similar idea a few years ago while driving to and from university on a country road. There were just too many dead animals. If the device could be programmed to emit predator sounds of a certain region, perhaps most animals would stay away. Perhaps linked to a sensor, the sounds would be emitted only when an animal is detected trying to cross the road. (There are a lot of cows along this road that I wouldn't want to bother though.) Country animals must get used to the sound of passing cars which perhaps to them sound more like a strange gust of wind than a dangerous object. Perhaps we need only to alter the sound a car makes (at high or low frequencies, if this makes more sense) so that a passing car sounds like something new to the animal. Simply randomizing these frequencies might be effective.
