Automatic registration of bumpy roads and potholes

If you think you've found a bug on the website which isn't specifically an App or Map Editor problem, or have a request for new or modified feature of the Community, Forums, or Waze website, use this forum.

This has been suggested before but I don't see it as workable, even the best phone accelerometers would struggle let alone the weaker ones. I also don't really see the need. As suggested above, speeds along these roads *should* already account for the road condition.


Screaming? So You don't want to be warned about cobbled surface? Even in foreign city/town?
- Switch of that feature and enjoy joggling!
Application could warn only about highest level problems on road. You see, in turn we would release users from imputing Alerts about situations which phone can notice it self.

Your city? How many cities/towns are in the world and how many of them have wise council deciders as Your city has? You don't have an idea! I can tel by my town. We have potholes around but budget for road repair this year is 2 and more less then before. I imagine You driving around and shiting at every 100m. We are speaking in global terms here. Not everywhere is Britain where one London's skyscraper has budget of some small or poor country. People may travel around and they would feel very comfortable if they would be warned about conditions which could have relative value for locals. Pothole in my country maybe is crater or wheel-braker for You. Intelligent registrator of bumps and holes could make it more objective. Still some brainstorming, pre-work must be done to figure out best solution which couldn't be annoying or useless, but make ride even more informative and comfortable... for those who need that...as option.

Also there would be possible to figure out algorithm of registering severe accidents for example if phone feels very hard acceleration, but user is not responding to phones questions after folowing stopping of car. We could warn local community that PROBABLY accident took place. Also, I am not telling that this is simple or it must be made simple. For sure there must be certain sequence of events to be at least 80% sure that this is related with accident.
Would it even save some lives or health problems? - Tell me!

Ok this problem is small and dealable. We can also avoid to ask questions and use only multiple repetitive expressions on acceleration/rotation graph.
Yesterday goggled about similar ideas. And look! - such data could be used for automatic suspension regulation - preventive preparation of vehicle for problematic conditions on road. Fantastic!
Why me and other users must use another application for that purpose if waze could take care of that?

Many cities already are using waze for traffic information. So let's give them info about real conditions of roads and spots of potholes as well!

Why not let Waze do what it does, learning average speeds? I don't know any mapping solution that reports rough roads and frankly... I think there are other things that Waze can and should prioritize.

Who told that such things are easy? Waze is not easy. But You can win only if You have more and more unique features. Would I download Waze if it had all same features as other navigators do? - Not. So don't please look at others and think what else waze could be useful for. Waze is not only about navigating, but giving useful info about road You are willing to take.

My argument against Your's: At different conditions wazers could drive at same spead, esp. where speeds are limited, or there are other (permanent/non-permanent) reasons for slowing down. Or for example - country road is flat and smooth, but dusty or slipery. In such case You (probably) still will be limiting Your speed, but not spoiling car or waking Your child. Other argument is that characteristics of different cars are different and in bad conditions speeds can be very different and not telling about condition of road. Agree?
I would not waste my time here if this feature could not be useful at least for me.
I agree that different cars will act differently on same bad road, but for that we have techniques of filtering, interpolation and other methods. Maybe it seems more difficult then it really is after exploring a bit.
Maybe some mobile application developer could contribute with prototyping such module wich could be tested on different cars on same bad roads, analyzing these differences, problems, cases/scenarios. Unfortunately I am not coder but I am experienced in leading projects and generating ideas for solution. It could be some parallel project, maybe even interesting for students and researchers and then, after it ready and trust-able, implemented in waze application and system.

One additional idea: if waze feels that device is frequently accelerating and rotating, it could ask if device is mounted. Note that waze must take in account accelerations which are hard(but not impossible) to imitate by human - sharp, rapid, short, vibrant. And also, in account could be taken data recorded at certain minimum speed.

True, If it will work, its a nice addone!
You have my vote ;-)

Well in the way you explain it to me, it is possible.
But (sorry) I think they can better invest in better navigation in all the country's before implent this sort of features.


As I understand, navigation quality depends on maps corrected by users and also number of users reporting. In country like mine and other with small road providing budgets, and percentage of gravel roads, info about road quality and dangers is vital. Navigation, so far, is decent. Ok - it could be made in next version, but when it will work - waze will be even more genius.

In the Netherland we have many and I mean many "drempels", that are little bumbs in the road that prevent people to drive to hard. Also it is very depending on how accurate the device is, some device have good accuration and some other thinks that you are falling 10KM without moving you hand.

Its also to hard to implent it, dev must do resource how the device shakes and what typ of road it is. What if you dont have a holder and you going hard right or you let it fall ? Phone flies away and waze makes a hazard or bad road condition. ;-)
Also if you cant drive that good or you have mechanical problems that the car shakes when you give gas? I think its just to complex to intergrate it into waze.

New car's have a system tat when you make a emergencybrake, the alarm light are going on, maybe waze can inplent this with making a 'car stopped', but also then you must avoid the phone is fly in your car or you let them drop.

Sorry for bad english


Sorry :) but You could not be developer, because I read only pessimistic opinion.
What was made inside waze is way more difficult then solutions for road surface quality registration. It could be made differently. Lets'take logic and tools available.

- info about bumpiness or any shaking quality of road could be shared only after comparing several user crossings of same section of road. These indices must be compared and filtered out bounces which are not corresponding with most of cases. But if after share appears additional "shake" - user could be asked for explanation like "what was that?"
- waze must be able to detect device type, model, and using this info make these devices more or less trustable. After comparing graphs of shaking, different device models could be sorted by their sensitivity, and precision.
- also 2 different cases must be taken in account: constant shaking, like on country road, pavement, etc; and sudden or rare, permanent and short-term obstacles like holes, "drempels", grabage, transition between road surface materials, etc.

Off course solution is not too simple. Its some work with research, analyzing, testing. But it can be done and I think - quite easy for waze dev team. I am stil sure that this feature could be very useful, and even life saving, because some holes or drempels may be missed in fog or other conditions with limited visibility. And imagine how useful it could be for road provider or clerk to monitor problematic spots form REAL and actual data! Another gain form waze.
