tim-day-387 / Nagel-Schreckenberg-simulation

A fork of a Nagel-Schreckenburg simulation, intended to add intersections and multiple roads.

Nagel-Schreckenberg Simulation

Traffic simulation based on Nagel-Schreckenberg model with:

• n lanes
• traffic lights
• speed limits
• obstacles
• intersections

Running the Model

To run simulation:

python nagel.py config.someLights

How to create simulation?

Copy existing simulation in config directory, and read the comments in sample configs.

Lane change model

In each iteration

1. Car checks maximum speed it can achieve on it's current position (x, lane) and adjacent lane (x, lane+1).
2. If the potential maximal speed on lane+1 is higher it checks safe conditions:

• There is no car car on (x, lane+2) to avoid collision caused by two parallel cars changing lane to lane+1.
• Distance to previous car on lane+1 is greater that it's speed to avoid emergency braking of previous car.

3. Change lane with probability P.

Same steps for lane-1
