GTFSync

GTFSync is a Python-based tool designed to detect changes, update identifiers, and merge GTFS (General Transit Feed Specification) datasets across time periods. It simplifies the process of maintaining clean and consistent GTFS data by automating comparison, synchronization, and integration workflows.

Core Modules

GTFSync is composed of three modular tools:

• Transit Detect Module
  Compares two GTFS feeds file-by-file to detect added, removed, or modified entries. Offers high-level, mid-level, and detailed summaries.

• Flow Update Module
  Scans and updates identifiers such as trip_id, route_id, stop_id, shape_id, and service_id across related GTFS files to ensure synchronization between feeds.

• Seamless Merge Module
  Merges multiple GTFS feeds into a single unified feed, appending suffixes to identifiers to prevent duplication and maintain data integrity.

System Requirements

• Python 3.7 or higher
• pandas library (install with pip install pandas)
• Standard libraries used: os, collections, difflib

No external dependencies or installations beyond Python are required.
