A metro/subway flow simulation.
I am quiet a fan of transportation systems. I used to play a lot to OpenTTD: an open source version of Transport Tycoon.
I was always fascinated by the (almost) perfect synchronization that the train systems have.
A few statements about this experiment:
-
There is no API connected to the app: I was considering the idea of using an API to get the data, but the problem is that it becomes a "visualization" rather than a simulation.
-
It is based on the Barcelona subway net, but can be easely modified to display any system.
-
It includes a simple "AI":
- Trains unload and load cargo on each station
- Trains decide when to wait or enter to a waypoint/station by status (free/occupied)
- Trains have a predefined itinerary and routes that have to follow
- Stations get cargo (passengers) to be delivered to other stations
- Trains have different capacity (1, 2, 3 or more wagons)
- Trains max speed is affected by the cargo and the size of the train
- Trains may have failures (not yet implemented)
I created this project as a fun way to learn a bit more about Typescript and PIXI.js
The simulation is fixed to display the Barcelona subway, but it is very easy to change to any city, you just need to define a Subway line and the coords for each station. Take a look the src/lines folder.
