Dr John Pucher's latest paper is quite brilliant:
Infrastructure, Programs and Policies to Increase Bicycling: An International Review.
Co-authored by Jennifer Dill of Portland State University and Susan Handy of UC Davis, it highlights the efforts and results of a number of international locations who are working towards increasing cycling as transport.
I've blogged previously about a seminar with John Pucher from Simon Fraser University in Vancouver right here. It's a lengthy videocast, but well worth it.
The newest paper is impressive for it's amazing amount of scientific references. Truly a thorough work, as well an an inspirational one. It's available for download from Pucher's Rutger website, under publications.
This is from the introdution:
"Bicycling is healthy. That is the conclusion of an increasing number of scientific studies assessing the impacts of bicycling on levels of physical activity, obesity rates, cardiovascular health and morbidity.
"The combined evidence presented in these studies indicates that the health benefits of bicycling far exceed the health risks from traffic injuries, contradicting the widespread misperception that bicycling is a dangerous activity. Moreover, as bicycling levels increase, injury rates fall, making bicycling safer and providing even larger net health benefits.
"Perhaps due to the increasing evidence of the health benefits of bicycling, many government agencies and public health organizations have explicitly advocated more bicycling as a way to improve individual health as well as reduce air pollution, carbon emissions, noise, traffic dangers, and other harmful impacts of car use.
"Countries and cities with high levels of bicycling and good safety rates tend to have extensive infrastructure, as well as pro-bicycle policies and progams, while those with low bicycling rates and poor safety records generally have done much less."
Just our cup of tea. Well worth a read.
There are also some stat boxes near the end in the reference area that highlight the increasing mobility in cities choosing to embrace bicycle culture. It's not really a newsflash, but increased bicycle infrastructure reduces injury, as well as all the health and societal benefits. So let's build those cycle tracks.
