conveyal / analysis-ui

Front-end for Conveyal Analysis. Model and analyze transport scenarios.

Analysis UI

This is the user interface component of Conveyal Analysis, which allows users to create public transport scenarios and evaluate them in terms of cumulative opportunities accessibility indicators.

Please note that Conveyal does not provide technical support for third-party deployments of Analysis. We provide paid subscriptions to a cloud-based deployment of this system which performs these complex calculations hundreds of times faster using a compute cluster. This project is open source primarily to ensure transparency and reproducibility in public planning and decision making processes, and in hopes that it may help researchers, students, and potential collaborators to understand and build upon our methodology.

R5 v6.4

The UI requires R5 version v6.4. Later versions of R5 no longer work with this repository.

Additional context
Trying to set up a local copy of R5 v6.4. I have the backend running (as far as I can tell) and am trying to get front-end set up now. FYI I am pretty new to TypeScript & JS dev concepts and getting my feet wet. Coming over from using OTP1 for analysis and urban planning data work. Hoping I am not totally off on how I should be building/running this front end. If there are good CLI tools to use the backend, and it's generally not advised to try to build this front-end, I would happy to try alternatives.
