??Wrong Speed

I was traveling at about 60, 2 cars away from another wazer traveling the same speed. Waze showed he was traveling at 40 - I almost never see speeds above that. A while later we were both going about 30 and Waze recorded it as 10mph! This seems to happen often enough that it really doesn't help me. The other issue is that I can't tell, if there is traffic in one direction, which direction it is! ie north or south - Waze just shows lots of traffice. When I zoom in I still can't tell which side of the road it's on...... Any help? Thanks!

The data for other wazers should, generally, just be ignored.

If there is a traffic slowdown that Waze is tracking, then the road will change colors: yellow, orange, red, deep red. There are arrows on the road which move showing which direction the slowdown is in, as well as a speed sign at one end showing the current average speed over that slowdown.

Seriously I do not see any value in knowing the speed of fellow Wazers. That is raw data; I have Waze turn that into routing advice that helps. I do not want to/can do all the computations myself and I trust that computers are more fit for that.

How much delay will trigger a trafficreport depends on the segment(s) you are driving and how much historical data is available for that segment. Very short segments may not report traffic.

Once traffic is reported it propagates to wazers concerned within seconds - less than a minute by all accounts.

And what exactly do you want to compare with what? MapQuest and Google get their trafficdata from undisclosed sources. They both miss the granularity that Waze has (provided there are enough Wazers in an area) and only signal traffic on the big arteries and freeways.

They get data from cell phones like all the rest, but Google a better data set from the myriad of Android phones that are out there.

That makes sense but it would be very helpful to know if the speed is 30 or 60! I'm often on roads where I don't see yellow or red but the traffic maybe going 10 miles an hour for a mile or two and then picking up again. How big is the delay with other wazers and how long is the delay before the road turns to a different color? I wonder how it compares to MapQuest or Google maps?

Personally the fact that no one can see how fast I'm travelling on the waze app makes me very happy. And that car that you thought was next to you was using waze, probably wasn't. It was most likely a car a mile or so in front or behind you. There is an intentional delay in what other wazers see as your location. for that I'm very happy too.
