Rapidly Expanding Mobile Apps for Crowd-sourcing Bike Data to New Cities
Sean Barbeau Nevine Georggi , Julie Bond
Cities such as San Francisco, Atlanta, and Portland are using novel methods of data collection to learn more about the use of their bicycle infrastructure. These data can help transportation planners better design or upgrade bicycle facilities. San Francisco created an open-source project, Cycle Tracks, a mobile app used to collect bike path data from bicyclists’ smartphones. These data then were used in the SF-CHAMP travel demand model to forecast how attractive Bike Facility A would be…

Assessing State Efforts to Integrate Transportation, Land Use and Climate Change
Rebecca Lewis Rob Zako
Climate change is increasingly recognized as a threat to life on earth. “Continued emissions of greenhouse gases (GHG) will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of GHG emissions.” (IPCC WGI, 2013.)
The transportation sector accounts for almost one-third of all GHG emissions in the United States. Growing Cooler describes GHG emissions from transportation as comprised of a three…
