# Drinker fate analysis

Dash application with modelling the chances of safe-home return of a heavy drinker.

![](images/application_view.png)

The motion of the drinker is modelled as a 2D Brownian motion $\mathbf{B}_t$ with drift $\mathbf{v}$, so:

$$

\left(x_t, y_t\right) = \left(\mathbf{B}^{(1)}_t + \mathbf{v}^{(1)}, \mathbf{B}^{(2)}_t + \mathbf{v}^{(2)}\right).

$$

Cars appear at random, according to mixed Poisson process jump times (distribution used for modelling is simply uniform distribution). Cars move with constant speed.

## Files description

* `analysis.ipynb` contains conclusions from many simulations perfomed for different sets of parameters.

* `app.py` implements Dash application in which user can run the simluations for chosen parameters and check the fate of the drinker with their own eyes thanks to animation.

* `scripts/animation.py` contains a function creating Plotly animation.

* `scripts/utils.py` contains classes `Car` and `Drinker` and mixed Poisson generating functions.

* `scripts/simulation.py` contains function that returns the trajectories of a drinker and cars for chosen simulation parameters.

## Running the app

If you want to run the Dash application, please install packages listed in `requirements.txt` and run command

```shell

python app.py

```
