Various other advocacy groups press for stricter limits and better enforcement. The [[Pedestrians Association]] was formed in the [[United Kingdom]] in 1929 to protect the interests of the pedestrian. Their president published a critique of motoring legislation and the influence of motoring groups in 1947 titled "Murder most foul", which laid out in an emotional but detailed view of the situation as they saw it, calling for tighter speed limits.<ref>{{cite web|url=http://issuu.com/carltonreid/docs/murder-most-foul|title=Murder most foul|author=J.S.Dean|date=2010-04-18}}</ref> Historically, the Pedestrians' Association and the Automobile Association were described as "bitterly opposed" in the early years of United Kingdom motoring legislation.<ref>{{cite book|url=https://books.google.com/books?id=kjyua9Ood38C&q=Criminal+on+the+Road++By+T.+C.+Willett|title=Criminal on the road|page=102|year=1964|publisher=Tavistock Publications|access-date=2010-04-27|quote=Moreover it has been the result of a continued compromise between two bitterly opposed factions: those who are against the motorist and will do all they can to constrain him, and those who oppose constraints unless they are relatively minor in their effects. Examples of both sides are, respectively, the Pedestrians' Association and the Automobile Association. The survey also shows that motoring law in 1903 and 1930 wa framed by legislators who knew little of the motor vehicle.|isbn=978-0-415-26416-7}}</ref> More recently organisations such as [[RoadPeace]], [[Twenty is Plenty]], and [[Vision Zero]] have campaigned for lower speed limits in residential areas. In the United States, advocacy groups favoring stricter limits and better enforcement include the [[Advocates for Highway and Auto Safety]], [[Insurance Institute for Highway Safety]] and the [[National Safety Council]].

In the US, the DOT FHWA has written in a report that "For a given roadway type, there is a strong statistical relationship between speed and crash risk for speeds in the range of 15 mph to 75 mph (25 km/h to 120 km/h). When the mean speed of traffic is reduced, the number of crashes and the severity of injuries will almost always go down.".<ref>Methods and Practices for Setting Speed Limits: An Informational Report, page 4, April 2012</ref>
