Introduction

The micro-simulation executes the route plans and returns congestion levels. Since we do not have plans yet, we will at this stage see the traffic micro-simulation as something that moves vehicles along links and across intersections.

We use the same dynamics as we had used for the roundabout in Chap. 3. That is:

• The road is divided into cells of length 7.5 meters.

  We will only model links with single lanes.

• Each cell is either empty or occupied by exactly one vehicle.

• Vehicles move deterministically by one cell between time $t$ and time $t+1$ if the cell ahead is empty at time $t$.

• Across intersections, we will check that the first cell of the receiving link is empty.
