Show streets speeds all the time

[MarcL20]

Thats a problem then. We should be able to set the max speed of the road. With jams, people driving so slow and lot of data that corresponds to wrong road speed, that average will never go up.

It's not a problem. The averages are not for the entire day, but rather some smaller amount of time, however Waze hasn't said how small.

But the point still stands: just because traffic moves at 1/2 the speed limit for two-hours on specific segments during the evening doesn't mean, IMO, that Waze should consider that normal and not report a slowdown.

IMHO, it should consider that normal and should not report a slowdown. I find the Google traffic maps that have all highways here marked red during the rush to be most unhelpful. What's the point of alerting me to a fact I already know, that the traffic is slow when it always slow during the rush.

I'm not sure I agree, actually. But beyond that, if it considers that a road is running at its normal speed which is 1/2 the speed limit, is this affecting traffic avoidance? As I type this, I'm thinking "it shouldn't" and "I hope not" because traffic avoidance should still be based on transit times compared to alternate routes.

I can confirm that Waze ETA is affected by areas that are frequently jammed with traffic - whether or not there is a jam on the display. I notice this when there is a holiday and I can beat the ETA to my work by several minutes. Generally I can rarely beat the initial ETA on my daily commute.

Of course Waze has no concept of the speed limit - only the average speeds. But I understand what you are saying - if the average speed of a segment is 30 MPH at 8am and 65 MPH at noon that the slower average speed is due to traffic.

So in order for Waze to show a jam on a segment that has an average speed of 30 MPH at 8am, when the traffic is flowing at 30 MPH on a particular day they likely will have to modify their jam algorithm to also compare against average speeds at other times of the day. Likely this would really complicate their jam algorithm (and probably going to introduce other bugs...).

They could implement something to use both data: Max and average. Its not hard to do.

Are you a programmer? Of course it's hard to do, since they probably have some sort of public interface being used, and adding in a max speed data requires a (if written in Java, for example) new Class (they might be able to cheat it by making max speed an instance variable of an existing class, which will still require updating anything interacting with that variable, and in turn, anything interacting with that Class), with new methods, and a new interface, along with changing the existing classes, methods, and interfaces to adapt to this new class.

Depending on how integrated (and large) the code is (and how poorly designed it was), it could require dozens of hours to add. Then there will be bugs.

It's something that should eventually be implemented, but not now.

EDIT:

It's always simple when we write it out on paper (who would honestly think that adding one more value could potentially take hours), but then again, as my teacher said, the stupidest thing in this room is the computer

The hardest one we already have that its the average aquired by the client. Adding a Max speed in database is simple since it will be done by the editor and is just another data field that you will add to waze road registers. I dont know how is waze algorithm but instead of comparing just with the average, using existing methods "and" maxspeed shouldnt be difficult.

That horse is already dead. Please don't try to resurrect it. Any attempt to add a "speed limit" to segments is doomed to be wrong often enough to be effectively worthless, does zero to help traffic avoidance, and just heaps more work onto the community editors.
