OpenTimes is an interactive travel-time map of the United States. Click on any location, and instantly view an isochrone map that shows how far you can travel from that spot within different time frames and via various modes of transport.
But OpenTimes is more than just an interactive isochrone map. It’s also an open-source platform offering free, pre-computed travel times between United States Census geographies.
What is OpenTimes?
OpenTimes is a comprehensive database of point-to-point travel times calculated between Census geographies across the United States. Unlike proprietary services that charge for access to similar data, OpenTimes is completely free and open-source. All the data is pre-computed and available for bulk download, making it an invaluable resource for anyone needing to analyze spatial accessibility.
The project leverages open-source software and publicly available data to calculate travel times. From the data pipelines to the infrastructure and even the website, every component of OpenTimes is open-source and hosted on GitHub.
How OpenTimes Works
OpenTimes uses publicly available data and open-source tools to compute travel times between Census geographies. The data is pre-processed and made available for bulk download, allowing users to integrate it into their own analyses seamlessly. The project’s GitHub repository includes detailed documentation on how to access and use the data, making it accessible even to those with limited technical expertise.
OpenTimes was inspired by the OpenFreeMap project. Together, with mapping libraries such as Maplibre, these initiatives are helping to build a robust, free and open-source ecosystem for creating interactive mapping applications.
