Local authorities have come to realise that road humps and traffic calming measures save money, specifically, the $40,000 cost of a typical accident (£863,000 for a death).
Local authorities compete for a slice of the department of transport's £50m road safety fund on the basis of this cost-benefit analysis: It will cost less to stop people being killed than it does to clear up the mess. Many schemes achieve a remarkable, if macabre, 30-40% return on investment and have proved very popular with residents.
In some areas however, traffic calming has run into opposition, reports the paper. Ambulances and fire engines are slowed down and bus pasengers are given a bumpy ride.
