Would the report "Health Co-Benefits and Transportation-Related Reductions in
Greenhouse Gas Emissions in the Bay Area" answer the questions?

Abstract
Objectives. We quantified health benefits of transportation strategies to reduce
greenhouse gas emissions (GHGE).

Methods. Statistics on travel patterns and injuries, physical activity, fine particulate
matter, and GHGE in the San Francisco Bay Area, California, were input to a model that
calculated the health impacts of walking and bicycling short distances usually traveled by
car or driving low-emission automobiles. We measured the change in disease burden in
disability-adjusted life years (DALYs) based on dose-response relationships and the
distributions of physical activity, particulate matter, and traffic injuries.

Results: Increasing median daily walking and bicycling from 4 to 22 minutes reduced the
burden of cardiovascular disease and diabetes by 14% (32 466 DALYs), increased the traffic
injury burden by 39% (5907 DALYS), and decreased GHGE by 14%. Low-carbon driving reduced
GHGE by 33.5% and cardiorespiratory disease burden by less than 1%.

Conclusions: Increased physical activity associated with active transport could generate a
large net improvement in population health. Measures would be needed to minimize
pedestrian and bicyclist injuries. Together, active transport and low-carbon driving could
achieve GHGE reductions sufficient for California to meet legislative mandates.

Aging housing stock and our aging society. Is anyone aware of the impact of our aging
housing stock on the ability of older people to maintain and age in their homes? This may
be a serious issue. Any references or resources would be appreciated. I am developing a
position paper on how people seeking or in elected positions should be addressing our
aging population.

   Greetings, all - I?m reaching out to Health and
Transportation 
 listserv members in the hopes someone can point me in a productive direction.

 I have a planning commission that is struggling with the public health 
 benefits/impacts of compact, walkable urban development. On the one 
 hand they understand and appreciate the active transportation benefits 
 associated with this built form. On the other hand, the epidemiologist 
 on the commission argues that the increased impacts of air pollution 
 in an urban area more than offsets the benefits associated with active 
 lifestyle and so is working to prohibit urbanization measures along 
 our key transit corridors ? density, mix of uses, transit oriented development.

 I can find reams of articles on the benefits of active transport. And 
 I can find scholarly articles about transportation-related air quality 
 impacts on public health. What I cannot find is anything that brings 
 the two together in a way that sheds light about these considerations 
 in combination ? air quality impacts trumping active transport 
 benefits (or vice versa). This is further complicated by the studies 
 she is referencing which were done in major metropolitan areas. We are 
 a small, low-density metro area with a population of about 175,000 
 between three cities. Our principal arterials carry anywhere from 10,000 ? 18,000
vehicles per day.
 We have very little ?urban? land use form and are trying to more 
 effectively stimulate that kind of private sector investment along our 
 premier transit corridors where we have the beginnings of walkable, 
 mixed-use neighborhoods taking shape.

 Are you aware of any research that has looked at the trade-offs 
 between active transport and air quality impacts that might be useful 
 in this regard?

 Any insights are appreciated ? thank you!
