Killed by a Traffic Engineer

Thoroughly researched and compellingly written, Killed by a Traffic Engineer is the first book to uncover the lack of science
behind traffic engineering, leaving readers inspired to take action and demand streets engineered for the safety of people.

In the US we are nearing four million road deaths since we began counting them in 1899. The numbers are getting worse
in recent years, yet we continue to accept these deaths as part of doing business. There has been no examination of why
we engineer roads that are literally killing us.
Fixing the carnage on our roads requires a change in mindset and a dramatic transformation of transportation. This
goes for traffic engineers in particular because they are still the ones in charge of our streets.
In Killed by a Traffic Engineer, civil engineering professor Wes Marshall shines a spotlight on how little science there is
behind the way that our streets are engineered, which leaves safety as an afterthought. While traffic engineers are not
trying to cause deliberate harm to anyone, he explains, they are guilty of creating a transportation system whose designs
remain largely based on plausible, but unproven, conjecture.
Thoroughly researched and compellingly written, Killed by a Traffic Engineer shows how traffic engineering “research” is
outdated and unexamined (at its best) and often steered by an industry and culture considering only how to get from
point A to B the fastest way possible, to the detriment of safety, quality of life, equality, and planetary health. Marshall
examines our need for speed and how traffic engineers disconnected it from safety, the focus on capacity and how it
influences design, blaming human error, relying on faulty data, how liability drives reporting, measuring road safety
outcomes, and the education (and reeducation) of traffic engineers.
Killed by a Traffic Engineer is ultimately hopeful about what is possible once we shift our thinking and demand streets
engineered for the safety of people, both outside and inside of cars. It will make you look at your city and streets (and
traffic engineers) in a new light and inspire you to take action.
