This will be a clickable interactive guide to determining what instruction, if any, will be given at the junction between any 2 segments. There will eventually be encyclopedia style illustrations for the various configurations to visually describe the setup. This will formatted as a sequence flow through, to cover (hopefully) all variations.

Introduction

Understanding how and which instructions are provided requires first understanding a few concepts.

  • This page is discussing the instruction which will be provided by the Waze server (or not provided) when travelling from one segment, through a junction, and onto a second segment.
  • How Best Continuations work. Any time the destination segment is the Best Continuation there will not be an instruction provided.

Definitions

  • The segment you are on before going through the junction, in other words the segment you are coming from will be referred to as the origin, and corresponds to s-in in the the algorithm text provided by Waze staff.
  • The segment you will be on after the junction, in other words the segment you are going to will be referred to as the destination, and corresponds to s-out in the the algorithm text provided by Waze staff.
  • Any segments other the destination which leave the junction at an angle less than 44° will be referred to as other branches, and corresponds to s-N, or s-1,2,3,4... in the the algorithm text provided by Waze staff.
  • When the beginning portion two segments are directly on top of each other, meaning they both leave the junction at the exact same angle as each other, they will be referred to as an overlapping segment.

The interactive algorithm

The instructions

No Instruction

There will be No instruction given passing through this junction.

Turn Right

Keep/Stay Right

Exit Right

The instruction in a right hand drive country will be Exit right. In a left hand drive country this will give a Keep/Stay_Right instruction.

Turn Left

Keep/Stay Left
