Lane Guidance

Waze does not expect or want Lane Guidance to be applied to every available junction with multiple lanes.

Junctions that benefit from Lane Guidance

Lane Guidance can only be added to segments that have more than one exit direction.

Lane Guidance will appear in the client approx 1km in advance of a junction for mH road types and above, 500m in advance for lower road types.

Junctions that should not use Lane Guidance

Lane Guidance can not be added to roundabouts nor Junction Boxes. In preparation for Lane Guidance through Junction Boxes ensure that all turns are allowed within the junction box and routes controlled solely by the Junction Box.

Lane Guidance should never be used when a single lane is used for all directions, nor should Lane Guidance ever contain more lanes than are available to the user.

Adding Lane Guidance

Animated gif, you may need to click the image to load animation

1. Select the segment
2. Click on the Lanes tab
3. Click Add lane guidance for the appropriate direction of travel (you may only see 1 option)
4. Change the number of lanes to match the road layout (in the direction of travel only) at the point of the exit node

• The choice of Lane Guidance turns shown for each segment is determined by the angle of the exit segments, snapping to the nearest 45 degree angle

• This is not the same angles as used for verbal instructions, using the JAI script will help but is not always correct for Lanes. Example: Straight on (not instruction); Verbal: ±45 degrees from straight, Lanes: ±22.5 degrees from straight.

Select the lane check box(es) that apply for each of the generated turns

• You can override the suggested lane guidance directions by clicking on the arrow image on the

Disabling a turn with Lane Guidance will delete all store information, if the same turn is re-enabled in future Lane Guidance will need to be input again.

Changing the angle of junction segments that already have Lane Guidance may lead to issues with how Lane Guidance is displayed in the app. It is advised to add a Map Comment to junctions that include Lane Guidance

Do not split segments to provide Lane Guidance in advance of a junction, this will cause a loss of any and all Lane Guidance data on the segment.

H / # Junction mapping

For H or # junctions that are mapped at 90 degrees, have parallel segments, and have a median segment of 30m or less, Waze will combine Lane Guidance, using a heuristic approach, to give the appropriate images depending on the direction of the route through the junction. The Lane Guidance should be mapped in sections through the junction as shown below:

• 

  1. Add Lane Guidance approaching the junction

• 

  2. Add Lane Guidance to the median segment

• 

  3. Heuristics will combine them for the client

• 

  4. All directions mapped

Turn suggested by WME will not include u-turn option, this is created automatically by the system.

You should always add Lane Guidance to the entire H or # junction to prevent any unwanted instructions from an unmapped direction.

Removing Lane Guidance

To remove Lane Guidance, simply select the lanes tab for the segment, then edit lane guidance, then change the number of lanes to zero (0).
