In cities: 40km/h on larger (roads designed to pass traffic through the town) and 30km/h on smaller (streets between blocks and inner-city) is the standard in Norrköping and several other parts of Östergötland. (Sweden) This, among with _removing_ traffic lights, both in favour of roundabouts, right-side-rule, and raised plaza-crossings (cars have to give way to pedestrians&bikes) have effectively reduced the amount of person damage in collisions. Walking plazas have an interesting effect in that it can cause an increase in small bumper hits on cars, but they reduce the speed of traffic by a lot, and change the flow of the street.
