Compreendendo as instruções de Navegação

Nesta secção terá resposta a duas importantes questões:

• O que uma rotunda normal vs. não normal?
• Que tipo de instruções de Navegação vou ouvir?

Rotunda não normal

Uma rotunda dita não normal tem 5 ou mais nos de ligação

------------

A non-normal roundabout:

   Will give you a ‘take the X exit’ (with arrows around it) instruction.
   Has 5 or more nodes (Ex. Each segment of a split road connects at its own node.)
   Has irregularly placed nodes (this will be covered in the examples.)

A normal roundabout:

   Will give you a ‘turn right', 'turn left’ or ‘continue straight’ instruction.
   Has up to 4 nodes, and a central node.
   All nodes are aligned within "normal" range of the entry point.

A roundabout can be both normal and non-normal at the same time depending on your entrance node. Some examples will help explain:

   For the sake of simplicity, let’s look at a roundabout with three exits.
   The angle of the segment approaching the node does not matter, it can be similar to any of the segments below, or anywhere in between.
