Here are a few of the projects I am involved in:
- Transit Appliance Project
- OpenTripPlanner and OpenTripPlanner Analyst.
OpenTripPlanner is a project to create an open-source multimodal transit, pedestrian and bicycle trip planner. Out of the box, it can be used to plan trips combining multiple transit systems, walking and cycling. OpenTripPlanner Analyst is a companion program, using the same codebase, that can be used for calculating urban mobility and effects of service changes. I have worked on various features, including elevator support, graph debugging tools, and web app usability. If you’d like to get started, check out Frank Purcell’s excellent introduction.
- I’ve written quite a few small transit and GIS related tools, including a tool to put geotagged tweets into PostGIS, a tool to archive NextBus data, and a tool to synchronize an SQL database with a transit agency using GTFS-realtime. These and many other projects are available at my GitHub.
