autopysta 0.0.3.9

2D traffic modeling.

Autopysta

Autopysta is a python library for modeling 2-D highway traffic, it's written natively on C++ for better performance and wrapped in SWIG to be used in Python

• Important

  Only Python 3.8 works on Windows, other versions are not working due to problems with the .dll

  For Linux you can use any version from Python 3.8 onwards and there's also legacy support for python 2.7

  The 3.8 version is al compatible with Google Colaboratory

• Details

  The package comes with a .so file (Linux), a .pyd file (Windows) and a .py that uses those files depending on your OS

  There is no Mac OS support at the moment, but an implementation is planned for future realeses

• How to use

  Installation

  You can install Autopysta using the pip installer

  pip install autopysta

  To begin using Autopysta you just need to import the module on Python:

  import autopysta

  And now you can use all the functions available on the library

• Examples

  A quick implementation of Autopysta:

  import autopysta as ap
  
  
  geo = ap.geometry(1000, 1, 0, 1000)
  
  newell = ap.newell()
  
  # Since this example doesn't use lane changes we use the no lane change as our model
  lcm = ap.no_lch()
  
  creators_list = [ap.fixed_state_creator(newell, 20, 10),]
  
  total_time = 120
  
  # total_time must be a multiple of dt
  dt = 1.2
  
  pre_made_vehicles = []
  
  # We run the simulation
  simulation = ap.simulation(lcm, total_time, geo, creators_list, pre_made_vehicles, dt)
  
  results = simulation.run()
  
  # And plot the results
  results.plot_x_vs_t()
  

  This gives us the following output :

  INITIAL STATE SIMULATION
[simulation.cpp] Out of loops, getting the answer ready

  And the plot :
