Getting Started

All the data are generated beforehand to make it feasible to be uploaded to shinyapps. Thus if one wants to run the backend to generate their own data, consider looking at running backend server section

1. Clone this repository
2. Install RStudio
3. Open this repository in RStudio and press the Run App button

Addition data

Not all data that are present on the live application is available inside this repository, if you really needed it (for school projects and such), feel free to contact me on Telegram

Running the backend server

1. Make sure Java JDK (JDK 8 preferrably) is installed
2. Make sure the local port 8080 is not used
3. Run the following code in terminal/powershell/console from the root dir of this repo

cd server
java -Xmx2G -jar otp.jar --router current --graphs graphs --server

4. Have a look at the generator.Rmd to understand how the data are called and stored

Addition resources

The backend server runs a local OpenTripPlanner server. Take a look at their api documentation here

The isochrone generation was heavily inspired by https://xang1234.github.io/isochrone/. Take a look at the detailed explanation on the data that are generated/required to created an isochrone overlay
