2012 TRB Meeting Activities

The Bicycle and Pedestrian Data Subcommittee hosted and participated in several TRB Annual meeting activities held the week of January 21 - 26, 2012.  A summary of these activities can be found below.

1.  Bicycle and Pedestrian Data Workshop (Jan 22, 2012)

TRB Bicycle / Pedestrian Data Subcommittee (ABJ35(3))

2012 TRB Annual Meeting Workshop


As part of the activities associated with the annual Transportation Research Board meeting in Washington, the Bicycle / Pedestrian Data Subcommittee held a workshop on January 22, 2012.  The purpose was twofold:  First, the morning session introduced the committee to the assembled transportation community, providing background information about the committee’s mission and work; second, the afternoon session focused on discussions of research avenues, with the ultimate goal of developing a national clearinghouse for bicycle and pedestrian data.  The afternoon session, in particular, sought attendees’ input as to the focus of committee work.  Approximately eighty persons attended the workshop, although space constraints in the afternoon unfortunately limited what surely would have been a higher number.  During both sessions, posters sought volunteers to sign up for the subcommittee  and volunteer for website (including a glossary project) and research activities.

Liz Stolz (Chaparral Systems Corporation and subcommittee chair) opened the morning session by welcoming the participants and having those assembled introduce themselves and their affiliation.  Present were public agency staff, the private sector, advocates, academia, and the health community; geographically, attendees came from across the United States as well as several foreign countries.  Three presentations followed, grouping bicycle / pedestrian data into three areas, following a “T3 Approach” of Traffic Data, Traveler Data and Transportation Data.  Traffic Data, presented by Liz Stolz, concentrated on system utilization and performance, highlighting advances in the ability to gather data on the number of system users, examining parallels in data collection for other modes, and tackling the issue of establishing performance measures to gage the non-motorized modes.  Stacey Bricka from the Texas Transportation Institute offered a discussion on measuring travel behavior.  Following an overview of ways to ascertain travel behavior and traveller attributes, she highlighted some of the challenges facing data, both from the collection and the analysis phases.  Geographic Information Systems (GIS) provide an environment for displaying and analyzing transportation data as Scott Brady from the Delaware Valley Regional Planning Commission explained.  The morning session concluded with Jeff Frkonja from FHWA introducing some additional challenges that a non-motorized data collection program faces, such as weather affecting the decision to travel and whether two hour volume counts should be a component of the data program.

The afternoon session built on the data areas discussed in the a.m. by introducing research to the equation.  Thomas Gotschi of the University of Zurich gave an overview of data needs to support non-motorized research.  He used examples to highlight the rich opportunities that exist in existing datasets as well as the difficulty in establishing boundaries to the data to be considered.  This is due, he suggested, to the interrelationship of different data types.  Steven Jessberger from the Federal Highway Administration discussed the ongoing effort to standardize data reporting as well as the implications this would have on the creation of a National Bicycle and Pedestrian Data Clearinghouse.  Finally, Shawn Turner of the Texas Transportation Institute gave an overview of issues to consider when setting a research agenda and strategies for moving forward.  He touched on the importance of defining terms, respecting the uses of data, and considering privacy issues in the collection and dissemination of data.

Jeff Frkonja again took the podium to guide the attendees in a discussion of issues in data.  The discussion was broad, touching on areas such as the data types, value beyond our community, formats, management/ framework, clients.  A lively discussion ensued on the structure the committee had chosen – both the T3 system and the graphic representing the types.  The justification for the committee’s decision was explained and while other considerations will be noted for future guidance, the current system was determined to best serve as the starting point for committee activity.
