Planning processes are increasingly incorporating online map-based commenting platforms—a form of public participation geographic information systems (PPGIS), but few studies demonstrate the role and impact of PPGIS on actual changes in the built environment. Recent collaborative planning of bike share systems in the United States demonstrate large-scale deployment of PPGIS. Because of their relatively short planning and development timeframe, bike sharing systems also serve as a valuable set of planning cases for analysis—there are fewer intervening factors involved that could affect results, as compared with larger infrastructure changes. This study incorporates a mixed-method research design with spatial analysis of public-suggested bike share station locations against the actual stations as constructed, and qualitative analysis of comments. Results show that not only are there statistically significant patterns in where suggested stations are more close to built stations, but that the content of the comments relates to both rational analysis by the public, and appeals to the likeliness of possible futures.

Goldsmith Talks is an open-format series of presentations organized by UTSOA faculty, staff, and students. the series aims to encourage and promote presentations that are outside of the scope of the main lecture series. Examples are: invited seminar presentations, book talks, lectures by designers and scholars who may be in Austin for another engagement, round-table discussions, film screenings, product demonstrations, or any other activity related to research, scholarship, and teaching activities and at the school. The format provides a platform for encouraging the dissemination of work by visitors and members of our community. The goal is to raise awareness, increase access, and better integrate such events within the public life of the school.
