User:Nagamasa/Turn instruction override
WME provides an ability to override the turn instructions provided during navigation so that editors can customize those instructions to better match the reality of the road.
|There is to be no campaign to replace existing wayfinders, micro-dog-legs, or any other segment-based structure with a Turn Instruction Override. Also, restraint should be exercised to not use this feature to create an alternate default condition for a large area simply because you don't like the Waze default response.|

|Before you set a Turn Instruction Override, It is highly recommended that you consult with a State Manager or other senior editor.|
When in WME and you click on a segment and hover over a green or yellow turn connection/restriction arrow, both the Time-based Turn Restriction (TBTR) clock and the Turn instruction Override (TIO) speaker icon will appear. If the turn is red (restricted), then the override icon will not appear.
- Waze Selected (default) (this gives the default voice prompt turn, exit, keep right/left, which is defined by street names, angles, road types, etc)
- None (No verbal instruction is given)
- Turn left (The instruction "turn left" is given)
- Turn right (The instruction "turn right" is given)
- Keep left (The instruction "keep left" is given)
- Keep right (The instruction "keep right" is given)
- Exit left (The instruction "exit left" is given)
- Exit right (The instruction "exit right" is given)
- U-turn (The instruction "make a U-turn" is given)
When to use
This works well for one way segments that have a u-turn only lane. You can post a "u-turn" verbal prompt on the first left turn and "None" on the second one.
Streets not meeting at right angles
Also consider: The departure angle in Waze Map Editor is also shown in the app closure interface. Angles which are too close, under 20° can overlap in the app, and so should be avoided.
Depending on the length and angle of an at-grade connector, it may make sense for Waze to instruct "keep right/left" or "turn right/left". Use a TIO to ensure the app voices the most appropriate instruction to the driver. An example of an at-grade connector using an instruction override is shown below:
The image here is a composite showing both turns with the override set and which instruction has been applied in this specific case. Drivers continuing straight, the app will give the driver the instruction "stay to the right to El Cajon Blvd." For drivers getting into the on-ramp, the app will say, "turn to the left to I-8 W."
A default surface-road-to-on-ramp "exit" instruction may be overridden with a "keep" in rare cases when (a) the originating highway's continuation path is unclear (such situations often require wayfinders as well) or (b) the on-ramp's initial departure continues to share direction and pavement with the originating highway, either for an unexpectedly long distance, or leading to two or more subsequent distributor on-ramps that are better instructed as exits than the initial departure. The latter application avoids issuing multiple "exit" instructions for what is effectively the same on-ramp. Aside from the above situations, overriding the default "exit" instruction for surface-road-to-on-ramp departures is not encouraged (see below).
Continue onto on-ramp
To reduce confusion, it is advised to use the "Continue" instruction in situations like a street heading directly onto a highway or freeway onramp, such as shown here.
When not to use
A complex wayfinder is one where the legs (s-out) are named differently than the subsequent segments. The wayfinder segments are named for the Big Green Sign (BGS) verbiage for clarity.
For these kinds of wayfinders, a turn instruction override does not have the required functionality and should not be used.
An "exit" instruction for common on-ramp departures from surface streets, while not immediately intuitive for many new Wazers, is nevertheless Waze's current default. Overriding this default on a large scale could lead to problems. Meanwhile our only alternative, the "keep" instruction ("stay" in some voices), is not always significantly clearer. Except for rare cases, overriding the default "exit" instruction for on-ramps is not encouraged.
Identifying on the map
- The default way to determine that a turn has an override set is to hover over the turn arrow.
- Toolbox helps to make identifying turns with override instructions set.
