bmtc-gtfs

Unofficial GTFS dataset for BMTC routes, stops and timetables in Bengaluru. Raw data sourced from Namma BMTC app, parsed and saved as GTFS.

Motivation

• Why BMTC?
• Why GTFS?

Caveat

The source for the data and analysis in this repository are the routes, stops and timetables as displayed on the Namma BMTC app. However, the Namma BMTC app is not completely accurate, and is particularly unreliable for timetables and stop timings. Nonetheless, the data can be used to understand general trends in the BMTC network.

Due to the design of the Namma BMTC app, only routes with functional live tracking are included in the GTFS. Any missing routes may be due to live tracking unavailability and not necessarily due to the route being inoperational.

GTFS

GeoJSON

GeoJSONs can be found below:

• Routes
• Stops
• Aggregated Stops

Conversion into other formats can be done using free tools like mapshaper or QGIS

CSV

CSVs can be found below:

Validations

• gtfs-validator
• gtfsvtor
• transport-validator (Older versions of GTFS)

Scripts

• scrape.py: Scrape raw data from Namma BMTC
• gtfs.py: Parse raw data and save as GTFS
• valiate.py: Pass the GTFS through multiple GTFS validation tools
• analysis.py: Process the GTFS and output a GeoJSON representing the network

Raw JSON

Raw JSON data scraped from Namma BMTC can be found below:

• routelines.7z: Pointwise co-ordinates of each route
• stops.7z: Stops through which each route passes
• timetables.7z: Timetables for each route

  • HTML timetables
  • PDF timetables
  • Route series-wise maps
  • Directionality
  • Reachability
  • Redundancy
  • Access to amenities (education, health, recreation, employment)
• Features
