      Transportation (http://www.wsdot.wa.gov/research/reports/fullreports/765.1.pdf ).

      This study used detailed data to assess the impacts of various urban form
      factors on vehicle travel and carbon emissions. This analysis indicates that
      increasing sidewalk coverage from 30% to 70% of streets in an urban neighborhood
      would typically reduce vehicle travel 3.4% and carbon emissions 4.9%. Land use
      mix and parking pricing also had significant impacts. Increasing average parking
      fees from $0.28 to $1.19 per hour (50th to 75th percentile) reduces vehicle
      travel 11.5% and emissions 9.9%. Study results were used to develop a
      spreadsheet tool that can evaluate the impacts of urban form, sidewalk coverage,
      and transit service quality and other policy changes for local and regional

      Large North American Cities: Lessons For New York," University Transportation

      (http://www.utrc2.org/research/assets/176/Analysis-Bike-Final1.pdf ); summary
      This USDOT research report reviews trends in cycling activity, safety, and
      policies in large North American cities over the past two decades. The number
      of bike commuters in the USA rose 64% from 1990 to 2009. Over the shorter period
      from 1996 to 2006, the number of bike commuters in Canada rose by 42%, and the
      bike share of commuters rose from 1.1% to 1.3%. From 1988 to 2008, cycling
      fatalities fell 66% in Canada and 21% in the USA.

      (http://policy.rutgers.edu/faculty/pucher/TRA960_01April2011.pdf ).
      This paper reviews trends in cycling activity, safety, and policies in Canada
      and the USA over the past two decades. Cycling levels increased in both the USA
      and Canada, while cyclist fatalities declined. The commute mode share is more
      than twice as high in Canada as in the USA. Cycling rates rose much faster than
      average in the nine case study cities due to various programs that encourage
      cycling and improving safety.

      York City Department of Health
      (http://www.nyc.gov/html/doh/downloads/pdf/survey/survey-2011active-transport.pdf ).

      This four-page report describes the health benefits of active transportation
      in New York City. The analysis indicates that people who commute by walking,
      cycling or public transit achieve about twice as total exercise as automobile
      commuters, and so are much more likely to achieve physical activity targets.
      This survey can be a model for use in other communities interested in tracking
      physical fitness and health.

      Dude, Where Are My
      Cars? (http://daily.sightline.org/daily_score/series/dude-where-are-my-cars ).
      This series of columns by Sightline Institute blogger Clark
      Williams-Derry discusses various indications that motor vehicle traffic is
      growing much slower than predicted and in many cases has stopped growing
      altogether or even declined. This has important implications for transport
      policy and planning.

      (http://daily.sightline.org/daily_score/archive/2011/04/08/why-are-bars-forced-to-encourage-driving )

      In this brilliant essay, columnist De Place asks, “If we're going to sell
      alcohol widely -- a notoriously powerful drug that impairs motor skill and
      judgment, and that is lethal in large quantities - then perhaps it's not a great
      idea for us to require by law that alcohol purveyors provide parking. But we

      (http://www.cato-unbound.org/2011/04/04/donald-shoup/free-parking-or-free-markets )

      This report argues that the expectation of abundant free parking is the product
      of anti-market planning and bad for our communities.

      Policies," California Air Resources
      Board(http://arb.ca.gov/cc/sb375/policies/policies.htm ).
      This set of reports by University of California researchers summarizes how
      various transport and land use policies affect travel activity and emissions.
      This research is the first step in a long-term process to help strengthen the
      technical underpinnings of SB 375 and to identify important data gaps and
      research needs.

      (?) Neighbourhood Road Pattern That Saves VRU (Vulnerable Road Users)
      Lives," Accident Analysis &
      Prevention (http://www.sciencedirect.com/science/journal/00014575 ).
      This study compared the traffic safety impacts of various neighbourhood street
      patterns. Although all can provide comparable accessibility, the 3-way offset
      and fused grid patterns reduce accidents as much as 60% compared to grid and

      Lack of Time and Urban Health," Journal of Urban Health, Vol. 87, No. 2; at
      (http://www.springerlink.com/content/v5206257222v6h8v ).
      These researchers argue that emphasis on increasing urban traffic volumes and
      speeds contributes to ill-health by increasing accident risk, air pollution,
      inactivity, obesity and social isolation. Using the concept of ‘effective
      speed’, this paper demonstrates that attempts to ‘save time’ by increasing
      vehicle traffic speeds is often inefficient overall.

      When Deciding Where To Live," National Association of
      Realtors (http://www.realtor.org/press_room/news_releases/2011/04/smart_growth ).

      This survey explores Americans' preferences regarding neighborhood
      characteristics such as proximity to parks and shopping, walkability, and
      commuting time, and the trade-offs they may be willing to accept in order to
      obtain those neighborhood preferences. The study indicates that, although most
      households want a single-family home, they prefer living in a walkable community
      with nearby services, and would choose a smaller lot if it would keep their
      commute time to 20 minutes or less.
