Lane Guidance (LG) now works at intersections with a , H, T and structure.
For lanes over Roundabouts (MULRA) see the Multiple Lanes for RoundAbouts page.
For an explanation of the lane width, see the Road width page.
The distance to the intersection where LG is displayed depends on the road type:
- Highways: FW, Ramp, MH: 1000 meters
- Streets: mH, PS, ST etc: 500 meters
The WME LaneTools Dev script makes setting the LG a bit easier, so it is immediately visible on the map that LG has been set.
Lane Guidance editing is available for level 3 and up.
You will only see arrows for your direction of travel when there is also an instruction. Without turn instruction in the app so no arrows displayed.
We follow as much as possible the arrows on the signs and on the road surface.
When the arrows on the road surface deviate from the arrows on the signs, we follow the signs. Please note: Arrows on the road may be covered by snow or other road users due to traffic jams.
The arrows that the app chooses by default can be overruled, which is sometimes necessary with complex intersections. But also follow the arrows on the signs or on the road. (If it is ultimately a right-angle turn then a 90 degree arrow; if it is a deflecting turn then a slanted arrow.)
Once there are multiple lanes to choose from to go in a direction, enter LG.
If there are no separate lanes, no signs, no arrows, do not enter LG. Also not for exits on MH or mH.
If there are multiple lanes that turn in the same direction, you can enter them.
If arrows have not been applied to the road surface or signs in all directions, this will have to be done in WME. Lanes cannot be left empty.
Lanes that 'normal' traffic cannot use, such as public transport, are not yet supported and can therefore not be indicated yet, unless the intersection has already been adapted for this.
A rush hour lane is only included in the number of lanes in LG if both of the following conditions are met:
An instruction has been set to go straight to stay on the highway;
The rush hour lane is on the left.
We are not going to make any intersection adjustments for the time being to make the LG work.
Saving incorrectly set LG will result in no display in the app for all lanes of the segment in question. In WME you will see an exclamation mark at the junction node, and if you open the LG menu, an exclamation mark at the lane where it is incorrect.
Corners
The angles between the segments affect LG. WME automatically chooses the shape of the arrow of the LG based on the angle between segments:
For a right-angle arrow, the angle between segments should be between 68 and 112 degrees;
For a straight arrow, the angle must be between -22 and +22 degrees.
Everything beyond that becomes a turn arrow or extra sharp turn arrow.
This does not always have to be correct, and there are two ways to correct this. One is not necessarily better than the other, you have to consider what is better per situation.
Force arrows in the LG menu;
Adjust the angle between the segments.
If it doesn't matter, force arrows is preferred because of KISS.
Junction with mDL
Junction with mDL
You can adjust the angle of the segments by adjusting the geometry of one of the segments. A micro dogleg (mDL) is the most common method. If you use this method, pay close attention to which segment you are adjusting, and what the effect is on any intersection on the other side of that segment.
You can force the desired arrow by clicking on the arrow in the LG menu and clicking on the correct arrow. You will also see which arrow Waze chooses; it says “(Waze selects)” after it. After you save it, there will be an orange warning: “One or more modified lane indication(s)”. If you click on Change lane instructions you will see which one it concerns, because those arrows are also orange.
Comments
We do not replace heuristics (see below) with forced turns.
If you hover over an arrow in the LG menu, the exit arrow on the map will be highlighted to clarify which exit it concerns.
Exits and filter lanes
We use the following exit instructions and filter lanes on all highways and on most MH and mH roads:
Exit:
Weaving section:
Exit with taper:
Double exit without taper:
Crossings=
At intersections where there is a stop line, we ensure that exits are displayed entirely as their own lane, as shown below:
十-intersection: two intersecting two-way traffic segments (normal roads);
T-junction: a road split into two one-way traffic or a normal road ends at a normal road;
With one or more intermediate segments:
⛛-intersection: a T-intersection of divided roads;
H-intersection: a divided road is crossed by a normal road;
⋕-intersection: an intersection of two divided roads.
There are variants, but they can usually be traced back to the five above.
十-intersection and T-intersection
For this type of intersection, filling in LG is easiest: you fill in the LG exactly as the road layout is, because there is no intermediate segment. You then proceed as follows:
Set all turns, especially those that are not allowed;
Open the LG menu per segment and set LG according to the road layout
For Number of Lanes, the total number of priority lanes;
At Exits, the direction for each lane.
Keep the following in mind:
Road width is in the same menu, but does not affect LG.
Make sure that LG is set in the right direction; look at the A or B node.
Don't forget to click “Save” after the LG is set, otherwise nothing will change.
⛛-intersection, H-intersection and ⋕-intersection
At these intersections there is an intermediate segment, and then LG becomes a bit trickier: for one direction of travel you have to use two segments (1 input segment and 1 intermediate segment) LG are set. The best thing to do when setting up such an intersection is to enter LG direction by direction to keep it as clear as possible for yourself.
The conditions that must be met to achieve a working LG at these intersections are
Crossing roads with separate lanes
Both left and right turns are possible at the intersection;
The two parts of the shared carriageway (entrance and intermediate segment) are more or less in line with each other (maximum offset of 22°, see also the paragraph on corners);
The two intersecting roads are more or less perpendicular to each other (maximum offset of 22°);
The intermediate segment in question is 50 m or shorter;
The number of lanes entering the intersection is equal to the total number of lanes leaving the intersection (total number of lanes leaving the intersection = number of lanes on the intermediate segment + number of right turn only lanes on the entrance segment - in other words, there no new lanes are added or removed in the intermediate segment).
If this is met, LG can be set as follows:
Open the LG menu on the input segment;
Under Number of Lanes, set the total number of priority lanes;
Under Turns, set the right and straight turns as usual. You can also set the priority lanes for turning left as straight ahead;
Now open the LG menu on the intermediate segment that is an extension of the entrance segment;
Under Number of Lanes, set the number of lanes that turn left and go straight;
Under Turns, set the lanes for left turns and straight ahead;
In the example above, there are a total of four lanes, three of which are for straight ahead or left turns. This results in the app at the junction node of the input segment in the following image: Bestand:LG-NL-Arrow-up. png
The mechanism that ensures this is called heuristics.
Comments
Turn instructions are set at the location where the turn is made. So turn right on the entrance segment, and left on the intermediate segment. See below for straight ahead instructions.
The instructions are linked to the first junction node of the intersection.
LG can simply be set at intersections that have a Junction Box (JB) over them. This can simply be done by L3 editors, as long as the segments are locked at that level.
At an H intersection, the divided road has no intermediate segment. There, LG can be fully set to the input segment. Depending on the angles, this can also apply to parts of a ⛛ intersection.
Forced straight arrows on the input segment do not work for heuristics.
If there is one lane on the entrance segment for turning left (and possibly straight ahead), the intermediate segment will also only have one lane. This is the only exception to the rule that LG is not set for a single lane, otherwise the heuristic will not work.
Far Lanes
Far Lanes (FL) is another way to apply Lane Guidance. This not only allows you to set the LG for a single intersection, it also provides the option to indicate preferred lanes for a subsequent intersection. In principle, it is also no longer necessary to create wybertjes or long parallel segments in order to provide correct instructions; one junction node is now sufficient for this.
There are two options for applying FL:
FL1 - Through a Junction Box (JB) - available to L4+ editors;
FL2 - By Path - available for L5+ editors.
If FL1 has been applied, it is not immediately visible in WME. You will then need to open the LG menu to see if FL has been set. FL2 is recognizable in the map; then there is a light blue dot with a white arrow on the departure segment, provided that the map layer Paths is active. The LG menu looks the same as FL1.
Comments
In WME, FL is called Far Turns. In this article, Far Lanes / FL is used consistently.
During the rollout, global How To's have been written for FL1 and FL2.
Paths do not yet record speed data, a JB must be used for that.
FL1 and FL2 cannot be combined. A segment that is part of a JB cannot be part of a Path and vice versa. If something like this is necessary, the segment must be cut.
FL2 Paths may cross each other.
Using FL for one direction of a departure segment breaks the heuristic (if any). FL must then be set for all routes from the departure segment for which heuristics would normally be used.
FL cannot be used on connected segments; there must be at least 1 segment in between.
The LG arrows for FL must always be selected manually; there is no Waze selects preference.
For both FL1 and FL2 there is currently a restriction that the JB or the path may not be longer than approximately 1 km.
FL is not set to make only the LG arrows correct. It must add something functional.
Junction Box (Far Lanes 1)
FL will not be necessary for every intersection with a Junction Box. A normal ⋕-crossing over which a JB is placed does not need to be adjusted as far as LG is concerned. Only when there are multiple lanes for one direction and lanes in the same direction have different destinations, or if it becomes problematic at the next intersection if you use the wrong lane for that direction, FL is set.
In the example below, the situation for the direction of travel is indicated with the red arrow as follows:
2 Left lanes turn left from Vondellaan to Plesmanlaan;
1 Right lane turn right from Plesmanlaan to Darwinweg.
If you are in the left lane for turning left, it can be difficult to turn right at the next intersection. That segment is 56 meters, which can result in strange maneuvers if you are not positioned correctly, or a missed turn. This can be due to heavy traffic in the right-hand pre-sorting area, or heavy traffic on Plesmanlaan. It is therefore best to advise that the Wazer uses the right pre-sort box.
There is already a JB at this intersection, because traffic lights for the two intersections are coordinated. The JB then ensures that the speed is registered per route, instead of only on segments (see JB wiki page for more information about this). So although FL2 can be used for the situation itself, the presence of the JB forces us to use FL1.
If the departure segment (Vondellaan) is selected, this is the normal image:
Normal heuristics are set, so every user turning left will be offered both lanes. At most, the “Then turn right” instruction will make someone suspect that it might be useful to use the right-hand sorting box. To improve this, we proceed as follows:
Remove heuristic, because it is broken by the presence of FL:
Remove the LG on the intermediate segment between Vondellaan and Plesmanlaan;
On the departure segment (Vondellaan), uncheck the two normal straight arrows under Exits.
Set FL for the route Vondellaan - Darwinweg:
On the departure segment, check the middle lane at Far Turns;
Click in the empty box on the left and select the left arrow.
Set FL for the route Vondellaan - Plesmanlaan (necessary due to the missing heuristics):
On the departure segment, check the two left lanes at Far Turns;
Click in the empty box on the left and select the left arrow.
Comments
The short right turn remains set via normal LG, because for FL there must be more than 2 segments in the route. It is therefore not an option at Far Turns.
The instructions are set as normal. If there are specific instructions for the route, set them to the arrow pointing out of the JB.
This gives the following result
Another possibility
Another possibility is that pre-sorting must take place earlier for a certain intersection. In the example below, you must already pre-sort at the first traffic light (VRI1) in order to turn left - in particular - at VRI2. Must be, because arrows on the road are a mandatory driving direction. It is therefore not only pleasant, but also necessary to show the correct LG in Waze at VRI1. This cannot be solved with heuristics. In any case, the distance is too great; the segment between VRI1 and VRI2 is 75 m long. Moreover, heuristics are already applied at the intersection at VRI2, and this cannot be done twice in a row.
So FL must be set. Since the VRIs are also linked together here, FL1 using a JB is the correct solution. In addition, the JB is used to prohibit U-turns at the ⋕ intersection.
FL is set as follows:
Select the input segment and open the LG menu;
Uncheck all the boxes for Turns;
At Far Turns, set the arrows according to the signs. Because you are showing left turn arrows, you cannot set a See-and-Hear (S&H) instruction;
Remove the heuristic at the intersection at VRI2 - only for this route, the other heuristics should remain as normal.
Set the instruction (VI & TTS) on the JB route, but also on the exit of the intermediate segment of the ⋕ intersection itself.
The user sees this instruction when accessing VRI1. (The lack of VI & TTS is a bug that still needs to be fixed.)
Paths (Far Lanes 2)
If there is no Junction Box at an intersection, and it is not necessary to record speed data for a route, a Path can be used instead of a JB added. Another reason may be that there are too many exits to be allowed to register a JB (>16 currently).
Also for FL2, at least 3 contiguous segments must form a route. There is no maximum number of segments, but with more than 5 intermediate segments, the entire path must be selected instead of just the departure and exit segments.
De reden om dit Path in te stellen is de splitsing die in de spits ertoe kan leiden dat er al op het vertreksegment file staat voor de richting N206. Het kan dan moeilijk zijn om nog in te voegen op de rechterbaan, dus is het beter om al bij het vertreksegment de juiste rijstrook te adviseren. Andersom geldt dat ook; voor de beter doorrijdende strook naar Centrum wil je niet onnodig in de file staan.
In dit geval zitten er 5 segmenten tussen vertrek- en uitgangsegment, dus hoeven alleen die 2 te worden geselecteerd. Er verschijnt dan een groene route en een wit icoontje met een slinger, ten teken dat er een Path kan worden ingesteld. Dat icoontje wordt blauw als je er met je muis boven hangt. Als je de route en icoontje niet ziet, kunnen er verschillende dingen aan de hand zijn:
Je bent te ver ingezoomd en/of te ver van het vertreksegment verschoven in de kaart;
Er ligt een segment in de route in een JB;
Er zitten meer dan 5 tussensegmenten in de route.
Het maakt niet uit of je de kaartlaag voor Paths aan hebt staan of niet. Als je hebt opgeslagen, zie je op het Algemeen tabblad van het vertreksegment het Path staan. Dit is ook de plek om een Path weer te verwijderen.
Het instellen van de LG pijlen gaat weer via het LG menu. Ook nu volg je de pijlen op de borden en weg.
Opmerkingen
Houd het Path zo kort mogelijk. Laat ze eindigen op het eerste segment van een richting, ook al is dat een naamloos tussensegment.
Het selecteren van alle segmenten in een route om het Path in te stellen kan ook met 5 of minder tussensegmenten in de route. Je kan dan de route niet aanpassen, mochten er meerdere opties zijn.
Als er op een segment een RTC staat, dan is het geen probleem om een Path in te stellen.
Instructies
Instructies worden als normaal ingevoerd voor de afslagen zelf. Voor de JB Route of het Path voer je in wat er op de borden staat voor het moment dat de instructie wordt gegeven.
Zicht- en hoorbaar of Ga rechtdoor?
Zonder extra instructie krijgt een app-gebruiker geen LG te zien als deze rechtdoor gaat op een kruising. Wanneer dit wel gewenst is, kan dat op twee manieren ingesteld worden:
1. Door middel van een “Ga rechtdoor” Turn Instructions Override (TIO) op de afslagpijl zelf;
2. Door middel van een instructie bij de LG. Hierbij is er keuze tussen Alleen zichtbaar en Zicht- en hoorbaar (Z&H).
De keuze tussen Zichtbaar en Z&H zit ‘m vooral in de reden van het instellen. Als het slechts ter verduidelijking van een situatie is, is alleen Zichtbaar vaak al voldoende. Als er door de gebruiker een handeling moet worden verricht, is Z&H noodzakelijk.
Op eenvoudige kruisingen waar een rechtdoor instructie moet komen, maakt het niet uit of je een “Ga rechtdoor” Turn Instruction Override (TIO) gebruikt of dat je via het LG menu een Z&H instructie inschakelt. Wel moet je tussen één van beide kiezen, waarbij de Z&H de voorkeur heeft. Een belangrijk verschil is dat een Z&H instructie alleen kan worden ingesteld op een LG pijl voor rechtdoor, terwijl een “Ga rechtdoor” TIO altijd kan worden ingesteld. Een ander belangrijk verschil tussen deze twee is dat een TIO wordt ingesteld op het tussensegment, en een LG instructie op het ingangsegment. Dat betekent dat het moment waarop de instructie gegeven wordt ook verschilt, en dat wordt significant bij langere tussensegmenten.
Bij kruisingen met FL ligt het iets gecompliceerder. Als er een TIO is ingesteld, gelden daarvoor momenteel de volgende regels:
Als er een TIO is ingesteld op het ingang- of vertreksegment, dan wordt deze gebruikt ten faveure van een TIO op de route;
Als er in de route een TIO is ingesteld, wordt deze gebruikte ten faveure van een TIO op de route;
Als er alleen een TIO staat op de route, wordt deze gebruikt;
Elke TIO krijgt voorrang op een Z&H instructie.
Weefstroken
Voor weefstroken is voor invoegend verkeer een instructie nodig, want zonder instructie nemen die de afslag weer. Een gewone “Ga rechtdoor” kan niet, want gebruikers die al op de hoofdweg rijden moeten deze instructie niet krijgen. We lossen dat op met een JB.
De instructies worden als volgt ingesteld:
Selecteer het middensegment (feitelijk de weefstrook) en open het LG menu;
Stel op de rechtdoor gaande rijstroken een Z&H instructie in;
Selecteer het ingangsegment van de hoofdrijbaan;
Op de afslagpijl van de JB-route die de hoofdrijbaan vervolgt stel je een “Geen” TIO in.
Er wordt voor een Z&H gekozen, omdat de instructie dan voor de splitsing tussen afrit en hoofdrijbaan wordt gegeven. Bij een “Ga rechtdoor” TIO op de JB-route vanaf de oprit, komt de instructie bij het inrijden van de JB en dat is niet wenselijk. Om de Z&H instructie voor het doorgaande verkeer op de hoofdrijbaan te onderdrukken, stel je de “Geen” TIO in (stap 4).
