Podczas korzystania z aplikacji Waze serwery Waze używają algorytmów routingu, aby określić najlepszą ścieżkę dla danej trasy w danym momencie. Szczegółowe informacje na temat algorytmów routingu używanych przez serwer Waze nie są ujawniane publicznie, a poniższe oparte są na obserwacji, spekulacjach i niektórych informacjach ujawnionych przez personel Waze. Zakłada się, że działanie serwera routingu jest uważane za własność Waze i przewagę nad konkurencyją. Zakłada się również, że routing może ulec zmianie i że wszelkie ujawnione informacje mogą być niekompletne lub nieaktualne.

Routing oparty na kliencie

Calculating an optimal route is a difficult task. While the client device app has a routing algorithm included, this is not used unless there is no connection to the Waze server. Client-based routing only uses cached map tiles. It does not use real-time traffic data, reports or closures, because this information is not accessible. Therefore, it does not provide an ETA.

Żądania routingu

Gdy poprosisz o obliczenie trasy, aplikacja Waze zyśle żądanie do serwera Waze. Obliczona trasa jest następnie przesyłana z powrotem do urządzenia klienta i wyświetlana.

Żądania dotyczące routingu różnią się w zależności od ustawień wybranych na urządzeniu klienckim. W Nawigacji możesz wybrać:

• Zezwalać czy omijać autostrady
• Zezwalać czy omijać drogi płatne
• Ustawienia dotyczące HOV i winiet
• Zezwalać czy omijać promy
• Zezwalać czy omijać drogi gruntowe
• Whether to allow, never allow, or avoid long unpaved roads
• Zezwalać czy omijać trudne skrzyżowania
• Typ pojazdu
  • Szablon:Passageway has a type-specific penalty.
  • Segment restrictions allow or prevent travel by certain vehicle types.

Różne długości tras

Przycinanie

Wiadomo, że silnik routingu Waze nie jest w stanie obliczyć każdej możliwej trasy dla tras długodystansowych, dlatego używa skrótów, usuwając z rozważenia niższe typy dróg w środku dłuższych tras. Ten efekt jest powszechnie nazywany „przycinaniem trasy” i może potencjalnie spowodować dramatyczną zmianę trasy po lekkim wydłużeniu. W odległości większej niż pewna wartość progowa od początku lub celu trasy, drogi niższe niż określony typ zwykle nie są brane pod uwagę. Istnieją progi przycinania o poufnych, zmiennych, rosnących wartościach odpowiednio dla  Ulica ,  Główna ulica  i  Droga wojewódzka . Istnieją dowody, że Szablon:Droga główna nigdy nie jest przycinana.  Autostrada  i  Rampa  nigdy nie są przycinane. Mechanizm przycinania jednoznacznie uwzględnia typ trasy, więc ulica podstawowa z trasą typu drogi +1 zostanie przycięta na tym samym progu, co droga pomocnicza..

Trasy XL

Generowanie tras dłuższych niż 1000 mil w Waze było kiedyś niemożliwe, ale w 2018 r. wprowadzono nowy mechanizm dla bardzo długich (XL) tras. Mechanizm ten łączy wiele długich tras, aby wygenerować jedną wyjątkowo długą trasę. Aby zaoszczędzić czas i uniknąć przekroczenia limitu czasu, instrukcje i szczegóły geometrii są pomijane na środku trasy podczas wstępnego obliczania, ale są one tworzone i wyświetlane później, gdy użytkownik jedzie wzdłuż trasy. W zależności od wielu czynników, takich jak obciążenie serwera i typu dróg, trasy transkontynentalne mogą być obliczane w Waze za pomocą tego mechanizmu. Oczywiste jest również, że ponieważ trasy XL są kombinacjami krótszych tras, wspomniane przycinanie zachowuje się dla nich inaczej, tak że niższe typy dróg mogą pojawiać się na środku bardzo długich tras.

Real-time current road speeds

The routing server uses real-time road speeds (from recent Waze app users if available) and combines the average, historical speed of the segment broken down into 10-15 minute chunks. The time to pass through a segment is tracked separately for each route out of a segment. For example if a segment ends with only a left and right turn, then the routing engine isolates the time through the segment to turn left and the time through the segment to turn right. This detailed speed information is proprietary and is not displayed in the Waze Map Editor.

It is known that Waze prefers to use real-time reports of current road speeds over historical average road speeds. Waze also uses traffic congestion reports to reroute around slow traffic. The speeds of recent Wazers traveling on a road will be factored into the route given to subsequent Wazers traveling on the same road.

As the number and density of Wazers grows, this real-time data takes on a greater importance. This emphasis is partly a reflection of Waze's original goal to create optimal commutes. As Waze has grown to be used as a more general-purpose GPS navigation device over roads less traveled, the historical average road speeds becomes more important.

Since Waze uses the future expected time of arrival onto a road segment in order to calculate the expected speed on that segment, it cannot use real-time data too far in the future. So longer trips (on the order of 30 minutes or more) will include future time slots where current traffic data is not available when initially calculated. As the trip progresses, any real-time traffic data that is available causes the client to recalculate the route and the ETA.

Average road speeds

If the average or historical road speed is not correct, then the route may not be optimal. However, deletion of segments to reset average road speed is not recommended. Waze uses the data from Wazers traveling through the segments to update the average speed, and oftentimes an anomalous historical road speed is automatically corrected with further data collection. If Waze appears to disfavor the use of certain segments along a route, a number of other reasons can cause such a situation.

Time-of-day variations

Consider a road that most Wazers drive at 5 PM when the average speed is 12 MPH. At 10 AM when the road is clear and the average speed is 60 MPH, it is the best road to take. If Waze only has historical speed data from 5 PM, it will assume that the speed of the road is 12 MPH all day, and it may not recommend this road. As more people drive this road closer to the time of day when a given route is requested, Waze will get a better guess for the average speed at that time.

Shrinking window

If there are enough recorded speeds on a road, then Waze uses a shrinking window of speeds to better estimate the average speed at the current time. Waze uses the speed of each road segment (in both directions) in intervals as small as 30 minutes. So a two-way road might have up to 96 average road speeds in a day. It can be assumed that when there are insufficient records for an individual time slot, a wider time range is used (up to a full day). As the road is driven more at different times, the time slot shrinks. Additional information is used based on the day of the week. There is no evidence that Waze records speeds for larger date ranges such as months or seasons; however, it will update its average speeds relatively quickly when seasonal traffic patterns change.

Waze uses the average road segment speed for the time slot that applies at the time when a user is expected to arrive at that road segment. Because of this time window, Waze suggests different routes at different times of day. This is dependent on how many times are recorded on the roads along the route. If they're all recorded at about the same time of day, then the time window does not help. If 1,000 times are recorded at about 5 PM and 2 times are recorded at 10 AM, then the 10 AM average speed still is based mostly on times from around 5 PM.

Turn delays

On a segment of a road, a user's average speed can be very different depending on what is done at the end of the segment. Traffic going straight through a traffic light might go very fast while traffic turning left might wait a very long time. A freeway exit lane might go fast while traffic continuing hits congestion.

Waze has the ability to separately track the average speed of traffic that passes through a segment, but exits to different segments. The routing engine takes this into account. In the diagram, multiple times are tracked for traffic flowing through Seg4 based on the segments to which it exits. There are then two average drive times for:

• Seg4 to Jnct2 to Seg5

• Seg4 to Jnct2 to Seg6

Traffic building up on Seg4 that turns right to Seg6 does not affect the route timing for the traffic also using Seg4, but instead turning left to Seg5. For this reason it is important to keep long segment lengths before junctions as traffic congestion at the junction might affect exits differently.

To understand this problem better, consider if we add a short Seg8 between Seg7 and Jnct4. Let's say the traffic exiting Seg10 backs up all the way to Seg7 (easy enough, since Seg8 is short). Because Seg7 only has a single exiting segment (Seg8), the routing server is only able to collect a single average speed — it can no longer distinguish traffic by where it is going after Seg8. Now the through traffic going to Seg9 appears to Waze to slow down through Seg7, even though it doesn't in reality. At a minimum this causes an incorrect ETA for routing, and it might actually cause traffic to be rerouted unnecessarily, and less optimally, through another route. Hence, if there is a chance that traffic can go in different directions at a junction and that junction can experience different amounts of congestion, the segment before the junction should be kept long, or a junction box may be used.

Outdated and abnormal road speeds

Average speeds can change over time, and recorded times can be abnormal or wrong—and can stay wrong for a very long time. This may be due to users recording inaccurate speed data by doing things like walking, biking or sitting in their driveways with Waze open. Also, if [[Segment length|segments are less than Segment length/Minimum]] they may not be long enough to record accurate transition times. There is some evidence that abnormal road speeds and old road speeds are discarded, or at least not used in calculating the average speeds of roads.

Recalculation

When Waze receives notification of traffic conditions, it uses the actual speed of roads on your route, rather than the average speed. This is based on real-time closures and automatic traffic condition reports - light, moderate, heavy traffic or complete standstill. Manual reports of traffic jams and accidents are for display only and do not change routing.

ETA is updated in response to a user's progress on the route and in response to these real-time traffic conditions. If real-time traffic conditions make the given route significantly worse than alternatives, Waze may provide an automatic recalculation. The benefits of this are balanced against the perceived hassle of changing one's route.

Traffic lights and stop signs

Waze does not record the location of traffic lights. While some GPS navigation offers guidance like "turn right at the next traffic light" the information is frequently incomplete, incorrect or outdated. The consensus view is that Waze should not record the location of traffic lights.

Waze does take traffic lights and stop signs into account by noting the effect they have on traffic speed. Consider a traffic light with long waiting times. The road segment leading to that traffic light will have a low average speed. If the average speed (based on the average waiting time) becomes low enough, a longer route that avoids the light becomes the preferred route. This has been observed in practice and is an example of emergent behavior. Waze isn't programmed to avoid traffic lights but it does avoid slow roads; if the traffic lights make the road slow then Waze avoids them.

Some drivers regularly take longer routes — even winding through side streets — to avoid any stops or traffic lights. Waze has been known to suggest this, and also known to revert to waiting at lights when better average speed information is collected from the side streets. But note that this can be less than optimal due to the turn delays discussed above.

What to do if you think the generated route is wrong

1. Use the option to generate alternative routes. This might give you some clues as to why Waze is offering that route.
2. If you think there is a better route, check in the Waze Map Editor that all of its roads are connected, and all legal turns are allowed.
3. Communicate the problem. Possible means of communication include:
   • Report a map issue in the app and respond to comments on it.
   • Post a message detailing the problem route (origin, destination and a WME permalink) to the Navigation forum or your state's local forum.
   • Join your local community's Waze Discord server (accessible from your state wiki page). This will usually produce the fastest response from local editors.

You are the driver

Waze can never see that the traffic light is green going straight or know that today is a public holiday. It can offer you guidance as to what is the best route under average conditions. But you are the driver and you are in the best position to make the decision for today under today's conditions.

If everyone followed Waze directions and never drove on a new route, Waze might never learn that route is better. When Waze is recording your travels, every trip helps make Waze better for everyone. That includes when you think you know better. Sometimes you will be right. And sometimes you will be wrong. But it is better to find out you are wrong so you can choose the better route. And when you are right, all Waze users benefit by the sharing of your knowledge.
