Running a simulation in Symupy¶

In order to run a simulation you need two main elements:

A symuflow library. Although it is already within the dependencies you may retrieve the simulator via the conda package conda install -c licit-lab symuflow. This will obtain the traffic simulator library.
An XML file with an scenario

[1]:

from symupy.runtime.api import Simulator, Simulation
import os

bottleneck = os.path.abspath("bottleneck_001.xml")

Successful import of symupy
/home/docs/checkouts/readthedocs.org/user_builds/symupy/conda/stable/lib/python3.9/site-packages/conda/utils/lib
Default path: /home/docs/checkouts/readthedocs.org/user_builds/symupy/conda/stable/lib/libSymuFlow.so

First create a Simulator object, the simulator object is in charge of establishing a comunication with Symuflow

[2]:

s = Simulator()

Configurator: Initialization
Using default defined library path
Runtime: Initialization

Attach the simulation file to a simulator

[3]:

s.register_simulation(bottleneck)

Launch your simulation

[4]:

s.run()

Run step by step¶

You may interact with the simulation by running a simulation step by step

[5]:

s = Simulator()
s.register_simulation(bottleneck)
with s:
    while s.do_next:
        s.run_step()

Configurator: Initialization
Using default defined library path
