Public Transit Viewer

Viewer to interact with the Public Transit Service.

The streamlit based Python app allows users to query connections between two stops or generate isolines from a specific stop. The application supports the query parameters of the service to search specific connections or isoline.

Installation

Get the current release from pypi and start the viewer:

pip install public-transit-viewer

export NAVIQORE_SERVICE_URL=<SERVER:PORT>
ptv-deploy

Or run the viewer inside a Docker container:

docker run -p 8501:8501 -e NAVIQORE_SERVICE_URL=<SERVER:PORT> ghcr.io/naviqore/public-transit-client:latest

Access the viewer on http://localhost:8501.

Development

Configuration

Create a .env file in the root directory. And add a line telling the application to which service host it should connect. In Local Development this is typically a Java Spring service running on http://localhost:8080.

The required line in the .env file will then be: NAVIQORE_SERVICE_URL=http://localhost:8080

Note: you can also specify the NAVIQORE_SERVICE_URL in your operating system environment.

Starting the App

To start the app in development mode run following command from the root directory:

poetry run streamlit run public_transit_viewer/connections.py
