CMU’s Heinz College is an internationally recognized leader in data-driven public policy. Housed in the Heinz College, Traffic21 strives to be a leader of both innovative transportation technology and policy research to guide civic leaders in harnessing the power and managing the risks of intelligent transportation systems. Traffic21 & CMU researchers periodically produce policy papers intended to inform transportation decision making. These papers are generally informed by the research undertaken at Carnegie Mellon.
Below are such papers and transportation policy research publications from CMU faculty.

Societal Impacts of a Complete Street Project on the Forbes Avenue Mixed Urban Corridor
Complete streets facilitate multimodal travel by improving both transportation access and safety by emphasizing the user, not the automobile. Forbes Avenue, originally a 4-lane urban arterial (two lanes in each direction, with no dedicated bike lanes), was reduced to three lanes (one lane in each direction and a center turn lane) and two bike lanes. Policy assessment indicate that traffic volumes decreased by 11%–31%, bicycle counts increased by 160% and 280% during the peak AM and PM hours, respectively, and average PM2.5 concentrations were reduced from 9.1 μg=m3 to 7.6 μg=m3 when compared to preretrofit conditions. No crashes were reported by the Pennsylvania Department of Transportation in the five months following project completion. Results can help inform the decision-making process for transportation planners exploring complete street projects with similar community and roadway traffic characteristics.
