Traffic Generator

+

The tool generates a structured set of encounters for verifying automatic collision and grounding avoidance systems. +Based on input parameters such as desired situation, relative speed, relative bearing etc, +the tool will generate a set of traffic situations. The traffic situations may be written to files and/or inspected using plots.

+

A paper is written describing the background for the tool and how it works [paper]

+
+

Installation

+

To install Ship Traffic Generator, run this command in your terminal:

+
pip install trafficgen
+
+
+

This is the preferred method to install Traffic Generator, as it will always install the most recent stable release.

+

You can check your installation by running:

+
uv run trafficgen --help
+
+
+

See documentation for usage of the Ship Traffic Generator.

+
+
+

Development Setup

+
+

Install UV

+

This project uses uv as package manager. +If you haven’t already, install uv, preferably using it’s “Standalone installer” method:
+..on Windows:

+
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
+
+
+

..on MacOS and Linux:

+
curl -LsSf https://astral.sh/uv/install.sh | sh
+
+
+

(see docs.astral.sh/uv for all / alternative installation methods.)

+

Once installed, you can update uv to its latest version, anytime, by running:

+
uv self update
+
+
+
+
+

Install Python

+

The traffic generator requires Python 3.11 or later.

+

If you don’t already have a compatible version installed on your machine, you way install Python through uv:

+
uv python install
+
+
+

This will install the latest stable version of Python into the uv Python directory, i.e. as a uv-managed version of Python.

+

Alternatively, and if you want a standalone version of Python on your machine, you can install Python either via winget:

+
winget install --id Python.Python
+
+
+

or you can download and install Python from the python.org website.

+
+
+

Clone the repository

+

Clone the traffig generator repository into your local development directory:

+
git clone https://github.com/dnv-opensource/ship-traffic-generator path/to/your/dir/ship-traffic-generator
+
+
+

Change into the project directory after cloning:

+
cd ship-traffic-generator
+
+
+
+
+

Install dependencies

+

Run uv sync to create a virtual environment and install all project dependencies into it:

+
uv sync
+
+
+
+

Note: Using --no-dev will omit installing development dependencies.

+
+
+

Note: uv will create a new virtual environment called .venv in the project root directory when running +uv sync the first time. Optionally, you can create your own virtual environment using e.g. uv venv, before running +uv sync.

+
+
+
+

(Optional) Activate the virtual environment

+

When using uv, there is in almost all cases no longer a need to manually activate the virtual environment.
+uv will find the .venv virtual environment in the working directory or any parent directory, and activate it on the fly whenever you run a command via uv inside your project folder structure:

+
uv run <command>
+
+
+

However, you still can manually activate the virtual environment if needed. +When developing in an IDE, for instance, this can in some cases be necessary depending on your IDE settings. +To manually activate the virtual environment, run one of the “known” legacy commands:
+..on Windows:

+
.venv\Scripts\activate.bat
+
+
+

..on Linux:

+
source .venv/bin/activate
+
+
+
+
+

Documentation

+

To generate documentation use:

+
uv run docs/make.bat html
+
+
+

The html documentation will then be available in docs/build/html/index.html

Style Guide

+

All code shall be Ruff formatted.

+

References, details as well as examples of bad/good styles and their respective reasoning can be found below.

+
+

References

+ +
+
+

Code Layout

+
    +

  • Use 4 spaces instead of tabs

    • +

  • Maximum line length is 120 characters (not 79 as proposed in PEP-8)

    • +

  • 2 blank lines between classes and functions

    • +

  • 1 blank line within class, between class methods

    • +

  • Use blank lines for logic separation of functionality within functions/methods wherever it is justified

    • +

  • No whitespace adjacent to parentheses, brackets, or braces

    • +
+
    # Bad
+    spam( items[ 1 ], { key1 : arg1, key2 : arg2 }, )
+
+    # Good
+    spam(items[1], {key1: arg1, key2: arg2}, [])
+
+
+
    +

  • Surround operators with single whitespace on either side.

    • +
+
    # Bad
+    x<1
+
+    # Good
+    x == 1
+
+
+
    +

  • Never end your lines with a semicolon, and do not use a semicolon to put two statements on the same line

    • +

  • When branching, always start a new block on a new line

    • +
+
    # Bad
+    if flag: return None
+
+    # Good
+    if flag:
+        return None
+
+
+
    +

  • Similarly to branching, do not write methods on one line in any case:

    • +
+
    # Bad
+    def do_something(self): print("Something")
+
+    # Good
+    def do_something(self):
+        print("Something")
+
+
+
    +

  • Place a class’s __init__ function (the constructor) always at the beginning of the class

    • +
+
+
+

Line Breaks

+
    +

  • If function arguments do not fit into the specified line length, move them to a new line with indentation

    • +
+
    # Bad
+    def long_function_name(var_one, var_two, var_three,
+        var_four):
+        print(var_one)
+
+    # Bad
+    def long_function_name(var_one, var_two, var_three,
+            var_four):
+        print(var_one)
+
+    # Better (but not preferred)
+    def long_function_name(var_one,
+                           var_two,
+                           var_three,
+                           var_four):
+        print(var_one)
+
+    # Good (and preferred)
+    def long_function_name(
+        var_one,
+        var_two,
+        var_three,
+        var_four,
+    ):
+        print(var_one)
+
+
+
    +

  • Move concatenated logical conditions to new lines if the line does not fit the maximum line size. This will help you understand the condition by looking from top to bottom. Poor formatting makes it difficult to read and understand complex predicates.

    • +
+
    # Good
+    if (
+        this_is_one_thing
+        and that_is_another_thing
+        or that_is_third_thing
+        or that_is_yet_another_thing
+        and one_more_thing
+    ):
+        do_something()
+
+
+
    +

  • Where binary operations stretch multiple lines, break lines before the binary operators, not thereafter

    • +
+
    # Bad
+    GDP = (
+        private_consumption +
+        gross_investment +
+        government_investment +
+        government_spending +
+        (exports - imports)
+    )
+
+    # Good
+    GDP = (
+        private_consumption
+        + gross_investment
+        + government_investment
+        + government_spending
+        + (exports - imports)
+    )
+
+
+
    +

  • Chaining methods should be broken up on multiple lines for better readability

    • +
+
    (
+        df.write.format("jdbc")
+        .option("url", "jdbc:postgresql:dbserver")
+        .option("dbtable", "schema.tablename")
+        .option("user", "username")
+        .option("password", "password")
+        .save()
+    )
+
+
+
    +

  • Add a trailing comma to sequences of items when the closing container token ], ), or } does not appear on the same line as the final element

    • +
+
    # Bad
+    y = [
+        0,
+        1,
+        4,
+        6
+    ]
+    z = {
+        'a': 1,
+        'b': 2
+    }
+
+    # Good
+    x = [1, 2, 3]
+
+    # Good
+    y = [
+        0,
+        1,
+        4,
+        6,         <- note the trailing comma
+    ]
+    z = {
+        'a': 1,
+        'b': 2,    <- note the trailing comma
+    }
+
+
+
+
+

String Formatting

+
    +

  • When quoting string literals, use double-quoted strings. When the string itself contains single or double quote characters, however, use the respective other one to avoid backslashes in the string. It improves readability.

    • +

  • Use f-strings to format strings:

    • +
+
    # Bad
+    print("Hello, %s. You are %s years old. You are a %s." % (name, age, profession))
+
+    # Good
+    print(f"Hello, {name}. You are {age} years old. You are a {profession}.")
+
+
+
    +

  • Use multiline strings, not \ , since it gets much more readable.

    • +
+
    raise AttributeError(
+        "Here is a multiline error message with a very long first line "
+        "and a shorter second line."
+    )
+
+
+
+
+

Naming Conventions

+
    +

  • For module names: lowercase . +Long module names can have words separated by underscores (really_long_module_name.py), but this is not required. Try to use the convention of nearby files.

    • +

  • For class names: CamelCase

    • +

  • For methods, functions, variables and attributes: lowercase_with_underscores

    • +

  • For constants: UPPERCASE or UPPERCASE_WITH_UNDERSCORES +(Python does not differentiate between variables and constants. Using UPPERCASE for constants is just a convention, but helps a lot to quickly identify variables meant to serve as constants.)

    • +

  • Implementation-specific private methods and variables will use _single_underscore_prefix

    • +

  • Don’t include the type of a variable in its name. +E.g. use senders instead of sender_list

    • +

  • Names shall be clear about what a variable, class, or function contains or does. If you struggle to come up with a clear name, rethink your architecture: Often, the difficulty in finding a crisp name for something is a hint that separation of responsibilities can be improved. The solution then is less to agree on a name, but to start a round of refactoring: The name you’re seeking often comes naturally then with refactoring to an improved architecture with clear responsibilities. +(see SRP, Single-Responsibilty Principle by Robert C. Martin)

    • +
+
+
+

Named Arguments

+
    +

  • Use named arguments to improve readability and avoid mistakes introduced with future code maintenance

    • +
+
    # Bad
+    urlget("[http://google.com](http://google.com/)", 20)
+
+    # Good
+    urlget("[http://google.com](http://google.com/)", timeout=20)
+
+
+
    +

  • Never use mutable objects as default arguments in Python. If an attribute in a class or a named parameter in a function is of a mutable data type (e.g. a list or dict), never set its default value in the declaration of an object but always set it to None first, and then only later assign the default value in the class’s constructor, or the functions body, respectively. Sounds complicated? If you prefer the shortcut, the examples below are your friend. +If you are interested in the long story including the why‘s, read these discussions on Reddit and Twitter.

    • +
+
    # Bad
+    class Foo:
+        items = []
+
+    # Good
+    class Foo:
+        items = None
+        def __init__(self):
+            self.items = []
+
+
+    # Bad
+    class Foo:
+        def __init__(self, items=[]):
+            self.items = items
+
+    # Good
+    class Foo:
+        def __init__(self, items=None):
+            self.items = items or []
+
+
+    # Bad
+    def some_function(x, y, items=[]):
+        ...
+
+    # Good
+    def some_function(x, y, items=None):
+        items = items or []
+        ...
+
+
+
+
+

Commenting

+
    +

  • First of all, if the code needs comments to clarify its work, you should think about refactoring it. The best comment to code is the code itself.

    • +

  • Describe complex, possibly incomprehensible points and side effects in the comments

    • +

  • Separate # and the comment with one whitespace

    • +
+
    #bad comment
+    # good comment
+
+
+
    +

  • Use inline comments sparsely

    • +

  • Where used, inline comments shall have 2 whitespaces before the # and one whitespace thereafter

    • +
+
    x = y + z  # inline comment
+    str1 = str2 + str3  # another inline comment
+
+
+
    +

  • If a piece of code is poorly understood, mark the piece with a @TODO: tag and your name to support future refactoring:

    • +
+
    def get_ancestors_ids(self):
+        # @TODO: Do a cache reset while saving the category tree. CLAROS, YYYY-MM-DD
+        cache_name = f"{self._meta.model_name}_ancestors_{self.pk}"
+        cached_ids = cache.get(cache_name)
+        if cached_ids:
+            return cached_ids
+
+        ids = [c.pk for c in self.get_ancestors(include_self=True)]
+        cache.set(cache_name, ids, timeout=3600)
+
+        return ids
+
+
+
+
+

Type hints

+
    +

  • Use type hints in function signatures and module-scope variables. This is good documentation and can be used with linters for type checking and error checking. Use them whenever possible.

    • +

  • Use pyi files to type annotate third-party or extension modules.

    • +
+
+
+

Docstrings

+
    +

  • All Docstrings should be written in Numpy format. For a good tutorial on Docstrings, see Documenting Python Code: A Complete Guide

    • +

  • In a Docstring, summarize function/method behavior and document its arguments, return value(s), side effects, exceptions raised, and restrictions

    • +

  • Wrap Docstrings with triple double quotes (“””)

    • +

  • The description of the arguments must be indented

    • +
+

+        """This function does something
+
+        Parameters

Exceptions

+
    +

  • Raise specific exceptions and catch specific exceptions, such as KeyError, ValueError, etc.

    • +

  • Do not raise or catch just Exception, except in rare cases where this is unavoidable, such as a try/except block on the top-level loop of some long-running process. For a good tutorial on why this matters, see The Most Diabolical Python Antipattern.

    • +

  • Minimize the amount of code in a try/except block. The larger the body of the try, +the more likely that an exception will be raised by a line of code that you didn’t expect to raise an exception.

    • +
+
+
+

Imports

+
    +

  • Avoid creating circular imports by importing modules more specialized than the one you are editing

    • +

  • Relative imports are forbidden (PEP-8 only “highly discourages” them). Where absolutely needed, the from future import absolute_import syntax should be used (see PEP-328)

    • +

  • Never use wildcard imports (from <module> import *). Always be explicit about what you’re importing. Namespaces make code easier to read, so use them.

    • +

  • Break long imports using parentheses and indent by 4 spaces. Include the trailing comma after the last import and place the closing bracket on a separate line

    • +
+
    from my_pkg.utils import (
+        some_utility_method_1,
+        some_utility_method_2,
+        some_utility_method_3,
+        some_utility_method_4,
+        some_utility_method_5,
+    )
+
+
+
    +

  • Imports should be written in the following order, separated by a blank line:

    +
      +

    1. build-in modules

      2. +

    2. third-party modules

      3. +

    3. local application/library specific imports

      4. +
    +
    • +
+
    import logging
+    import os
+    import typing as T
+
+    import pandas as pd
+    import numpy as np
+
+    import my_package
+    import my_package.my_module
+    from my_package.my_module import my_function, MyClass
+
+
+
    +

  • Even if a Python file is intended to be used as executable / script file only, it shall still be importable as a module, and its import should not have any side effects. Its main functionality shall hence be in a main() function, so that the code can be imported as a module for testing or being reused in the future:

    • +
+
    def main():
+        ...
+
+    if __name__ == "__main__":
+        main()
+
+
+
+
+

Unit-tests

+
    +

  • Use pytest as the preferred testing framework.

    • +

  • The name of a test shall clearly express what is being tested.

    • +

  • Each test should preferably check only one specific aspect.

    • +
+
    # Bad
+    def test_smth():
+        result = f()
+        assert isinstance(result, list)
+        assert result[0] == 1
+        assert result[1] == 2
+        assert result[2] == 3
+        assert result[3] == 4
+
+    # Good
+    def test_smth_type():
+        result = f()
+        assert isinstance(result, list), "Result should be list"
+
+    def test_smth_values():
+        result = f()
+        assert set(result) == set(expected), f"Result should be {set(expected)}"
+
+
+
+
+

And finally: It is a bad idea to use

+
    +

  • global variables.

    • +

  • iterators where they can be replaced by vectorized operations.

    • +

  • lambda where it is not required.

    • +

  • map and lambda where it can be replaced by a simple list comprehension.

    • +

  • multiple nested maps and lambdas.

    • +

  • nested functions. They are hard to test and debug.
