Traffic calming
Traffic calming measures are changes to a road to make car drivers slow down and to make the road safer for people who have to walk across the road. Some traffic calming techniques include installing speed bumps and narrowing roads, which make drivers slow down. Another way to make drivers slow down is to set speed limits. These speed limits can be enforced with automatic speed cameras. These cameras take photographs of people who are driving too fast. Another way to slow drivers down is to make curbs wider.

Two traffic calming measures on a road in England which aim.to slow down drivers. The speed cushions (the two reddish raised pads or bumps) discourage fast driving. The curb extension (marked by the black posts and white stripes) extend into the road and narrows the area for driving, which tends to reduce drivers' speed.
