hello ,
i wrote this algoritm with python, but there is no vehicle in the network
during the simulation ?
there is the script :
#!/usr/bin/env python
# -*-coding:Latin-1 -*

__file__), '..', '..', '..', '..', "tools")) # tutorial in tests
sys.path.append(os.path.join(os.environ.get("SUMO_HOME", os.path.join(
os.path.dirname(__file__), "..", "..", "..")), "tools")) #
tutorial in docs
