How to simulate road traffic?

Question

Game development

It is required to build a realistic model of city traffic. Just a graph with random cars will not work.
It is necessary to simulate such phenomena as rush hour, traffic jams, accidents, the behavior of road users. Also calculate elementary physics: reducing speed when turning, avoiding obstacles, overtaking and changing lanes.
The model will be used to analyze changes in road infrastructure and ways to optimize traffic (choose a traffic light mode, build a new road, and so on).
Are there libraries or any other solutions so as not to reinvent the wheel?
What literature should be studied?

Answer 1

Here , you can press CTRL + U, scroll to the very bottom and read the scripts.

Answer 2

You open Google Scholar and read the first five to ten pages. After reading it, it may easily turn out that not only is physics not necessary for you, but in general transport networks can be tested without cars.

Answer 3

It may be interesting for you to pay attention to the analogies of car traffic and hydrodynamic processes. For more details, google "hydrodynamic theory of traffic flow".
