NxTransit
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 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
pip install nxtransit
