Where is this guidance?
It seems to me that add names to segments that are clearly for a road with a different name is bound to cause problems in the long run. To do so because the BDP may potentially be changed to penalize this route still does not seem like good practice to me.
Federal highways should be denoted as follows. Note that the trailing N, S, E, W cardinal direction indicator is used for numbered highways and interstates which are split into two 1-way segments

I consider this a serious issue. It makes it impossible for us to explain clearly.
Given that, we may as well go with a very simplified explanation that works 80%-90% of the time, insert a qualifier that there are other rules that may affect whether BDP is applied, and call it a day. It will be much more comprehensible to the uninitiated reader than the complete, very technical and detailed description of all we know, without deviating much more from the (unknown) BDP reality than that more complete description would provide.
Also, some of the back and forth above seems limiting in how the information will be used. Reader want to know:
* What BDP is
* How it works (as simply as possible)
* When BDP will kick in and when it won't
* When it is beneficial to force Waze to apply or not apply BDP (contrary to Waze's norm)
* How to force it to happen or not to happen in those situations
* Example, examples, examples, examples, examples, examples, examples, examples, examples, examples
* More examples. Seriously. There should be at least one example at every rule showing how it applies and where it fails.
* A more detailed technical reference with all teh caveats that we know about

I dare to consider myself experienced in Waze and had difficulty in understanding it. Without wanting to just criticise the work that has been done, it most probably won't be understood by new editors.

I think I disagree. Unless the address matching has greatly improved, putting cardinals on named highways where the cardinals are not typically used for address searches causes problems. Besides if this is not worldwide guidance, then the BDP should still be designed with the idea that there will be divided highways with the same name on both carriageways.PesachZ wrote:I will argue that I believe with the information above we have a very solid of how and when BDP today. Like anything in the routing engine, especially penalties, they are always in a state of potential flux. Therefore when we know that a specific limitation is only implemented due to processing constraints, as opposed to intended operation, it is prudent to assume they may improve the process to more accurately meet their intent at some point in the future. We therefore when designing guidance should do so in a manner that is compatible with the operation today, as well as the intent. This will give us configurations that work 100% of the time.
But if the current operation works better than the "potential" operation, like it does for edsonajj's example, shouldn't we tell the developers that changing it is likely to cause more problems than it solves?

I'd just state for the record that I believe that there are plenty of divided roads that are not limited access freeways and expressways and that these roads account for more than 0.1% of multi-segment U turns (particularly as there are destinations on such roads that require U-turns to get to and from).
