Research Highlights
National Study of BRT Development Outcomes
Arthur C. Nelson Joanna Ganning
Public transit systems are often promoted as offering a plethora of social, economic and environmental benefits to urban populations by transforming urban forms from auto-centric designs into more sustainable ones. The “next big thing” in public transit is bus rapid transit (BRT) systems. From virtually no systems a generation ago, there are now nearly 20 lines operating with at least seven under construction and more than 20 in the planning stages. Part of this recent popularity in BRT stems…

Overcoming Barriers for the Wide-scale Adoption of Standardized Real-time Transit Information
Sean Barbeau
Real-time transit information has many benefits to transit riders and agencies, including shorter perceived and actual wait times, a lower learning curve for new riders, an increased feeling of safety, and increased ridership. In the last few years, a real-time complement to the General Transit Feed Specification (GTFS) format, GTFS-realtime, has emerged. GTFS-realtime has the potential to standardize real-time data feeds and lead to widespread adoption for transit agencies and multimodal apps…
