My understanding was that these instructions used to be given, but then stopped. There was thus some question whether we should really be editing to make the instruction come back or whether waze should just bring the instruction back. I've heard nothing recently that indicates waze will bring the instruction back.
2) The detour prevention mechanism is only effective if the distributor/collector lanes don't exceed 5 kms. Is there any utility for these methods for very long distributor/collector lanes?
3) Waze did just confirm that one example of a routing off/on the freeway was due to the fact that the detour prevention is just a penalty that was overcome by very heavy traffic. Of course, we don't want waze to route off/on to avoid very heavy traffic (that's kind of the point). So the question becomes: is it worthwhile to employ both methods to increase the penalty as much as possible?
- I believe we should be editing to reflect reality where possible without a degradation in nav instructions (e.g., where they would suggest illegal movements). Editing to reflect reality will necessarily bring the instructions back (and the instructions are very important). The phrasing "editing to make the instruction come back" makes it seem like it would be a "hack" to do so, when really, the current Wiki suggestion is the "hack" here, one designed to prevent a problem that is essentially no longer a problem.
- Maybe not, but it has no bearing on this case. The current Wiki suggestion only envisions a single interchange; using a turn restriction at some point along a long collector-distributor to avoid detours without disallowing any proper routes would only work with some configurations and isn't something that should be suggested, I don't think. It'd take consideration and some experience to be able to tell where that'd be viable, if at all.
- Not if routing will be adversely affected. The "stay to the" instruction in question on a collector-distributor cloverleaf is crucial — you necessarily have to change lanes either way. No instruction pretty much means "keep going", which is basically always going to be wrong.
