Classes

class Scenario

ScenarioTemplate is a class that should be inherited by a Scenario class in order to generate xodr and xosc files based on pyoscx and pyodrx

Two main uses, in your generation class define self.parameters as either as - a dict of lists, where the lists are the values you want to sweep over, all permutations of these sets will be generated - a list of dicts, where the dicts are identical and each element in the list is one scenario

Attributes

road_file (str): name of the roadfile

parameters (dict of lists, or list of dicts): parameter sets to be used

naming (str): two options "numerical" or "parameter"

generate_all_roads (bool): will only generate unique roads

number_of_parallel_writings (int): parallelize the writing of the xml files
    Default: 1 (no parallelization)

basename (str): basename of the scenariofiles,
    Default: name of file

encoding (str): encoding of the outputs
    Default:
