New Paper Published

Transportation Research Part D published a new paper I co-authored with colleagues from Virginia Tech and UVA. Steve Hankey and Tianjun Lu lead this paper:

Lu, T., Buehler, R., Mondschein, A., Hankey, S. 2017. “Designing a Bicycle and Pedestrian Traffic Monitoring Program to Estimate Annual Average Daily Traffic in a Small Rural College Town,” Transportation Research Part D: Transport and Environment.

Here is the abstract:

Cycling and walking are commonly recognized as energy-efficient alternatives to motorized transport. Research and practice lack a comprehensive set of methods to assess spatio-temporal patterns of traffic volumes across an entire transportation network. Current non-motorized traffic monitoring programs are primarily implemented in urban areas and for singular components of the network (e.g., off-street trails, specific corridors). Our approach synthesizes ongoing efforts in non-motorized traffic monitoring to estimate Annual Average Daily Traffic (AADT), across an entire network in Blacksburg, VA – a small, rural college town. We selected count sites across the network, stratified by street functional class (e.g., major roads, local roads), centrality of the link relative to origins and destinations, and planned bicycle facilities. We collected 45,456 h of pedestrian and cyclist counts using three types of automated counters: pneumatic tube (n = 12), passive infrared (n = 10), and radio beam (n = 3) at both reference locations (n = 4; 1-year) and short-duration locations (n = 97; 1-week) during 2015. We found a strong correlation between manual validation counts and automated counts. We used day-of-year scaling factors to estimate AADT for bicycles and pedestrians and found that temporal and spatial patterns differed between modes. Pedestrian volumes were higher and more variable than bicycle volumes (median [interquartile range] AADT for pedestrians: 135 [89–292]; bicycles: 23 [11–43]); both modes were positively correlated with street functional class, presence of facilities, and proximity to campus. Our approach provides insight for planners or policymakers interested in comprehensive monitoring programs to track performance measures  or for use in environmental and health impact studies.

Talks in England and Media Mentions

In March I gave two invited presentations in England. One at the University of Westminster for the London Cycling Campaign and one at Oxford University. The talks were titled “Reducing Car Dependence: Lessons from Europe and the USA.” The presentations were mainly based on the papers below:

Buehler, R., Pucher, J., Altshuler, A. 2017. “Vienna’s Path to Sustainable Transport,“ International Journal of Sustainable Transportation, Vol. 11, No. 4, 257-271.

Buehler, R., J. Pucher, R. Gerike, T. Goetschi. 2017. “Reducing car dependence in the heart of Europe: Lessons from Germany, Austria, and Switzerland,” Transport Reviews, Vol. 37, No. 1, pp 4-28.

Our work was also mentioned by two media outlets:

Congratulations to PhD Candidate Marc Fialkoff

The post below is taken from my colleague Ralph Hall‘s website. Ralph and I are co-chairs of Marc’s PhD committee.

“Congratulations Marc Fialkoff (PGG Doctoral Candidate) for being selected as a 2017 Eno Transportation Fellow. The Eno Center for Transportation is non-profit foundation whose core mission is the study of emerging issues in transportation policy and the cultivation of future leaders in the field.

Marc is the first student in the School of Public and International Affairs at Virginia Tech to be selected as an Eno Fellow. As a Fellow, Marc will travel to Washington D.C. in early June to participate in the Eno Center Future Leaders Development Conference.

As a doctoral candidate and a lawyer, Marc’s research is at the intersection of law, transportation policy, civil engineering, and network science. His research focus on freight transportation resilience was awarded a HERE Dissertation Support Grantby Oak Ridge National Laboratory in 2016, where he carried out his research into the effect of the Jones Act on freight transportation movements after Hurricane Sandy. His research has been published in the Critical Infrastructure Report and the International Journal for Critical Infrastructure Protection.

Marc’s committee represents the interdisciplinary nature of transportation policy, with committee members from Urban Affairs and Planning, Civil and Environmental Engineering, Law, and Network Science. I currently co-chair Marc’s committee with Ralph Hall, along with committee members Kathleen Hancock, Henning Mortveit, and Jonathan Gutoff.”

Poster Presentation at 10th University Transportation Center (UTC) Spotlight Conference: Bicycle and Pedestrian Safety

Last week I presented a poster at the 10th University Transportation Center (UTC) Spotlight Conference: Bicycles and Pedestrians. The poster was based on our forthcoming paper in the American Journal of Public Health:

Buehler, R., Pucher, J. forthcoming. “Have Walking and Cycling Become Safer? Recent Evidence from High-Income Countries, with a Focus on the United States and Germany,” American Journal of Public Health.

Here is a link to the poster presented at the University Transportation Center (UTC) Spotlight Conference: Bicycles and Pedestrians Safety.
