text: Have a petition signed by all of your neigbors.  Make sure to have a good argument to why you think they are needed.  Then present the petition to your local councilman/councilwoman (politically correct).\n\nThat is what I would do.\n\nA lot of people do this for long roads (typically 25mph roads) where people speed a lot to get speed bumbs installed.\n\nGood luck!
