**NxTransit** is a Python library designed to build and analyze multimodal graphs of urban transit systems using General Transit Feed Specification (GTFS) data. This tool allows for detailed, time-sensitive analysis of public transit accesibility.

See the [documentation](https://nxtransit.readthedocs.io/en/latest/) for more information.

## Key Features

### Multimodal Graph Creation

NxTransit integrates GTFS with OpenStreetMap (OSM) data to create a multimodal graph representing an urban transit system.

### Time-Dependent Calculations

The package enables the detailed analysis of transit systems by incorporating time-dependent nature of public transportation. This includes:

- GTFS feed validation.
- Shortest path calculations with time-specific departures.
- Generating travel time matrices to evaluate travel durations between multiple network points.
- Service area and "typical" service analysis.
- Frequency analysis.
- More features are planned for future updates.

### GTFS Data Support

NxTransit utilizes GTFS data, a common format for public transportation schedules and geographic information.

### Installation

```bash
pip install nxtransit
```

### License

Package is open source and licensed under the MIT license. OpenStreetMap's open data [license](https://www.openstreetmap.org/copyright/) requires that derivative works provide proper attribution. This package heavily depends on [OSMnx](https://geoffboeing.com/publications/osmnx-complex-street-networks/) by Geoff Boeing, which is also licensed under the MIT license.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.
