VAG Stats Tracker

Install

Goal

Features

ToDo:

• Track delays of everything
  • Bus
  • U-Bahn
  • Tram
• Live Map of ALL services
• Generate Heatmaps of delays
• Geoline API - Get exact WGS84 coordinates for lines with rails
• Stops API
• Toplist

Things i´d like to do but got not enough time for:

• Easy way to report delays or other stuff (Not directly to the company)
• Smart warnings of potential delays
• Link common delay causes to the average delay they cause
• Track Elevator malfunctions and duration
• Smarter departure lookup endpoint
• Smarter connection lookup endpoint
• Something like Flightradar24s "People on my plane"
• Smart alexa alarmclock (Alexa, wake me up so i´ll be in scool by 8 o´clock)
• New API Methods to extend the VAG PULS API (If i figure out how to install PGSQL Plugins, lol)
• More...

Real Time Map

Vehicle + Accessibility info

For private vehicles this information isn't avaible and the VAG also doesn't know all the Vehicles (Laziness on their part)
Bus: (Operator) Displays AC Avaibility, Wheelchair Spots and Fule type (Diesel, Gasoline, Gas or Electro)

Tram: (Operator) and Door configuration (Wheelchair accessible or not)

Delay Heat Map

Displays all delays of a date or timespan on the map

Install

Windows

Requirements:

• Docker Desktop
• NodeJs 20
• PGAdmin (or other PG Interface)
• Some IDE
• Redis Insight (Optional)

Steps:

1. Create containers with docker compose up -d in some powershell window in the root of the repo.
2. Use SQL Tool (PGAdmin) to generate a DB. Default user admin and password adminpassword
3. You need to make a .env Can be fond below File in all programs you wanna use:
   • FahrtenProcessor (Tracks a ongoing trip)
   • FahrtenScanner (Finds new trips)
   • WebService (Provides /metrics endpoint and all API routes)
4. Run programs in order, start al programs from their root:
   • Go into /WebService and run node index.js wait till it its ready
   • Go into /FahrtenScanner and run node index.js (If you already had it running run node /tools/clearRedis.js to wipe the cache)
   • Go into /FahrtenProcessor and run node index.js
5. You know its working when Scanner shows a lot of things realy fast, and Processor starts picking up all the jobs over the next couple of seconds

Project (The kickstarted still didn´t deliver :/)

Unlike my other projects this project will be built around my learning curve to cloud like software architecture.
Target Hardware:

• 4 Nodes each with:
• 8x ARMv8 SoC
• 16 GB DDR4
• 1 TB NVME
• 1 Gbit/s LAN
