Developing reproducible transit analysis with R
Regular talk, 1:30 - 2:30 PM
Jarrett Walker & Associates (JWA) is a planning consulting firm that has led bus network design projects that shape the map of transit networks in major cities throughout the US from Portland to Miami Cleveland to Houston and many more in between.
Throughout all its projects JWA relies on R as the cornerstone of its analysis approach. Learn about how JWA has leveraged the GTFS and other transit data standards to apply technically complex analyses for transit agencies of all sizes. JWA has invested in building around the growing R transit package ecosystem developing its own packages and training its staff in the R skills needed to put it all into practice. This has enabled our company to reduce reliance on closed-sourced tools and put more control over our analysis in the hands of the people tasked with running it.
Some of the topics that will be discussed include: • Wrangling GTFS data. • Conducting advanced travel time and job access analysis. • Visualizing transit data. • Evaluating mobility and equity outcomes of new transit plans. • Designing repeatable workflows that can be quickly learned by people with different coding skills levels.
This presentation will serve both as an introduction into analyzing transit data in R as well as a window into how transit planning practitioners work in R in real-world settings including Portland.
