John Joseph Leeming, (1899 – 1981), BSc, ACGI, FICE, MI Struct E, MI Mun E, F Inst HE, was a British civil engineer and traffic engineer. He forwarded controversial ideas for the causes of, and remedies for, road crashes, including the notion that drivers should not always be assumed to be at fault.
Leeming was born in 1899 and served in the First World War. From 1924 he worked in various road engineering capacities for Oxfordshire County Council, latterly as Deputy County Surveyor until he left for Dorset in 1946. Leeming supervised the rebuilding of some historic bridges in Oxfordshire and what was then Berkshire, including Abingdon Bridge in 1927, Cropredy Bridge in 1937 and Shilton Bridge in 1938. He wrote or co-wrote articles about these bridges that were published in the Oxford Architectural and Historical Society's journal Oxoniensia.
In 1946 Leeming moved to work for Dorset County Council as County Surveyor, where he stayed until his retirement in 1964. In this period he pioneered road accident investigation. In 1969 his book Road Accidents: prevent or punish? was published. A 2007 review of a reprint of the book described it as controversial, and as being written by an "enlightened highways expert".
Road crash causes
In Road Accidents: prevent or punish? Leeming set out his ideas and views of the causes of road casualties, and of how best they can be tackled. The book is described as attacking the beginnings of the blame culture, with Leeming convinced that road casualties could be reduced by using road engineering methods based on evidence derived from the scientific analysis of the causes of road crashes, and that drivers were not the main cause of many road safety problems.
Motorways and bypasses generate traffic, that is, produce extra traffic, partly by inducing people to travel who would not otherwise have done so by making the new route more convenient than the old, partly by people who go out of their direct route to enjoy the greater convenience of the new road, and partly by people who use the towns bypassed because they are more convenient for shopping and visits when through traffic has been removed.
It can safely be said that places which look dangerous do not have accidents, or very few. They happen at places which do not look dangerous. The reason for this is simple. The motorist is as intelligent as the ‘local people’. If a place looks dangerous, he can see that it is so, he takes care and there are no accidents.
