Ian Stewart asserts that his university’s mathematics students “earn more money, on average, than those studying any other degree subject” and that “their ability to handle technical ideas is highly prized, and rewarded” (Letters, June 7). His assumption, shared by most other contributors to the current debate about maths […]

Martin Parkinson raises an interesting question (comment on previous post): what should be the reaction to an accident that, a priori, was an extremely low probability event? He suggests that “any attempt to reverse the counterproductive aspects of ‘health and safety culture’ is doomed to failure”. After an accident he argues that most people […]

Traditional highway engineering assumes that safety requires the spatial segregation of pedestrians, cyclists and motorized vehicles or, where this is not possible, rigorously enforced rules, signs and signals dictating temporal segregation. Road users, according to the established paradigm, are irresponsible, stupid, selfish automatons whose safety can […]

The words “risk” and “management” sit uncomfortably alongside each other. Many people believe that it is possible to distinguish “real”, “actual” or “objective” risk from “perceived” risk. But all risk is perceived. It is a word that refers to the future, a future that exists only in our imaginations.
Those who call themselves risk managers purport […]

On the first of February 2008 I sent an email to the Department of Transport at - road.safety@dft.gsi.gov.uk. It said:
“In your press release of 31 January you state: “Seatbelts have prevented an estimated 60,000 deaths and 670,000 serious injuries since 31 January 1983 when seatbelts were made mandatory for drivers and front seat passengers.” […]

Anniversaries are convenient occasions on which to reinforce myths. Twenty five years ago, 31 January 1983, it became compulsory for occupants of the front seats of cars in the UK to wear seat belts. Today Britain’s Department for Transport has posted a press release announcing that in the 25 years since the seat belt law […]

In October 2007 the Insurance Institute for Highway Safety published a Status Report (PDF: 1MB) complaining about my article “Britain’s Seat Belt Law should be Repealed” (PDF: 0.2MB) (published as “Seat Belt Laws – Repeal them?” in the June 2007 issue of the statistical journal Significance). It went on […]

Amazon Review (*****):
Risk and Freedom is a book of historic significance. Published in 1985 and out of print for many years it continues to have a profound influence on road safety policy. It provides the first coherent application of the concept of “risk compensation” to the management […]

There is a growing enthusiasm amongst European transport planners for “shared space”. It is an intriguing idea pioneered by Hans Monderman, a highway engineer in Friesland. He removed almost […]

“We are in danger of having a wholly disproportionate attitude to the risks we should expect to run as a normal part of life.” So said the Prime Minister in May 2005. At the highest […]
