If you are using the new editor do the Shift-A thing and look for red arrows on your route. I got the impression you can be routed through them but it costs more. Since we are playing on an evolving field, every little trick helps. (You will want to turn those arrows green and if you do the Shift-A twice after a save they are shown correctly again) Good luck and keep us posted on the results. You might also try routing with the "avoid highways" option turned on and see what it does. It is usually very interesting.

If you ask for alternate routes, yours should be one of them. If you have the settings on fastest route, learning turned on, and there are not dirt roads to avoid etc. it should include your route. If you go the Waze way with Waze on a few times, it should learn that that route is slower, but it sounds like you already did that. I know it worked at one time but I have not tried it lately. This topic seems to pop up every once in a while.

I've been told by Dror to ignore the speed numbers in old cartouche, that navigation isn't using those at all. He didn't actually state it, but I inferred that he also was trying to say that they may not be accurate, since they aren't used, they may not being updated (correctly?)

I have a workaround for this problem. I'm sure that there are others who do the same, but I haven't heard it mentioned in this discussion:

At the point along my preferred route which is the farthest deviation from the route that Waze always suggests, I create a favorite, either with a street address, or by tapping and holding on the map at that point. The next time I want to take MY route, I choose my usual destination, wait for Waze to plan the route its way, and then "Add a Stop", at which point I enter my off-course favorite. In most cases, Waze will then map out the whole route the way I like it. It's an extra step, but it's effective, and sometimes this approach has helped Waze to finally see it my way, apparently since this is causing Waze's routing servers to actually calculate my entire route, rather than only the portions of it that are left when I have refused to follow its suggestions.

Also, if your preferred route uses roads designated as "street" anywhere but the beginning or end, Waze will not want to take you that way.

Do you have the home and work favorites set and do you usually navigate there?
It should figure it out in less than a week if thats the case.

In my route to work, getting off the freeway has two routes that are possible. What appears to be the shorter of the two is what Waze "usually" uses, but I never take that route because sometimes I find heavier traffic on part of it and there is a long light required for a left turn. When I take my route it of course will recalc to my route and show my distance increased by 0.5 miles, but the time is about the same. Because my route does not have that left turn light I don't stop driving. I hate to wait. :D

Periodically (1 per week or few weeks) Waze will select the route I always take. At those times I can see there is usually heavier traffic on the normal route. So I know Waze will take an alternate route based on traffic. I guess the route it proposes is actually faster most of the time, but psychologically I like not stopping.

Note that there are a few times I have seen it route me a 3rd direction further down the freeway. I usually find no issue with my normal route, so I am not sure why it ever selects that route over mine.

The only assumption we can make is that there is not heavy Waze usage in your area yet. When we recommend that people drive the slower route so Waze routing servers can learn, that is assuming that there isn't anyone else on the road using Waze driving that route. When there is heavy Waze usage in an area, Waze will get that data from other drivers and learn that it's slower without you having to drive it.

What city are you in?


I am in Hanover, PA, and I drive to York, PA. I agree there are probably not many other Wazers in the area at this time. I don't see any other driver icons on the route I take either way.

Andy and Alan,

In fact, the road I travel every day is free of errors, etc on the map. The problem here is that the alternative route takes 15 minutes more time in the morning, and I don't really have time to drive it, unless I get out earlier - a challenge with my family.

In principle, I find this a weakness of the application. It is tracking my drive every time I have it on, the road I am on is visible in the waze map, and it is demonstrably error free. The application should, based on my history alone, determine that this is a viable alternate route.

Thank you for confirming the current mechanism of route learning. If my route does not show up after I inconvenience myself for a week or so, I will be removing the app.

Perhaps this is answering my question:
" Waze should always pick what it believes is, mathematically, the fastest or shortest route, depending on your settings. If, in your estimation, it doesn't, that means that there could be an error in the map somewhere along your preferred route, or there is a lack of correct speed/traffic data for that route, or lack or correct speed/traffic data on the route it is trying to send you on. If it isn't too far out of your way, take the suggested route a few times and Waze will collect and start to use that data in its routing decisions.
The reason just driving the expected or preferred route won't work automatically is because Waze could have incorrect speed data on the segments it wants you to take. If Waze thinks another road is 2x as fast as your preferred road, no amount of driving on your preferred road can change the data for the other road. Waze needs accurate data for all neighboring segments and routes in order to always compute the fastest (or shortest, depending on your app setting) route."

So if I demonstrate to Waze that my route (my drive) is faster by driving its slower alternate route a few times, it should pick this up and offer my drive as a possible route?
