list of data standards, APIs, apps, tools, datasets, and research around
open source technology of public transit.</h5>
<p>Open technology provides an opportunity for various stakeholders to
collaborate efforts to improve public transit.</p>
<p>Elements of open technology include: - Open standards - Open data -
Open source software (both as consumer-facing apps like OpenTripPlanner
and developer tools like the GTFS Validator)</p>
<p>This list is focused around the open technology ecosystem for public
transportation. Included technologies may be open source themselves
and/or rely on open standards and/or open data.</p>
