Figure 4.1: UML diagram: Road and Drivelane

represents all intersections, those with traffic lights and those without traffic lights
(NonTLJunction which is a subclass of Junction). The subclasses of SpecialNode
are EdgeNode and NetTunnel. At an EdgeNode road users will start and end their
trip.

4.2.3 Roadusers and how they move

Roaduser is the most super class representing all road users. It has 2 subclasses:
Automobile and Bicycle. Roaduser and Automobile are abstract classes. Automo-
bile has 2 subclasses: Car and Bus. The roadusers have an attribute pos, which
represents their current position on the lane. This position is changed by its ac-
cessors at other places, like in moveLane.
