Thank you for taking the interest on the open-source work I have been collaborating in the past years! Here is a collection of the material I showed on me slidedeck:

R Packages Link to heading

At IPEA, while working on Access to Opportunities project, I collaborated extensively on developing R packages that utilize GTFS data. For some packages, I contributed directly to the coding phase, and for all, I actively participated in discussions, suggested improvements, and reported bugs.

In addition, I have started developing my own R packages. One package currently in development is gps2gtfs, which uses public transport GPS data to correct GTFS feeds based on scheduled data. This package applies the method I developed in this paper as part of my PhD research.

This package is under heavy development, with expected release for December/2024

Web applications Link to heading

I have also developed a number of web applications (using the R Shiny framework) that used different type of public transport data (such as GTFS, smartcard, GPS), such as:

Fortaleza's (Brazil) Public Transport System (SIT-FOR)

Shinyapp with routes, bus lines and general information about SIT-FOR

GTFS Explorer (beta)

Explore GTFS feeds: routes, trips, speeds
