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

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[list], list[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
basename : str
basename of the scenariofiles, default: name of file
encoding : str
encoding of the outputs, default: utf-8
