Inappropriate navigation
When there is slow traffic on the motorway, ABRP often chooses to suggest leaving the motorway via the exit and then taking the descent back onto the motorway again, in order to get ahead of the slow-moving traffic. This is not good
- Where does this happen?
- ABRP version number (found at bottom of settings menu)

In general this seems like a small optimization and also anti-social behavior. It’s especially bad when you’re not familiar with the area. Since ABRP doesn’t tell you what it’s doing and since it is not always so obvious that you’re being directed off and then right back on (I’ve sometimes been sent down a frontage road for a mile or so which means that you can’t see that you’re just dodging a short bit of traffic) this is really annoying. It can be very stressful to get to an exit in the midst of a traffic jam and you don’t know if you’re being directed off because that’s the next step on your route, or if you’re just trying to avoid traffic and will be getting right back on.

Hi
We are aware of this problem and yes it’s not a very good solution. This is because there is no traffic jam on the exit.

A couple of things:
This bug still exists, so it shouldn’t be marked completed. To me at least that implies that the problem has been resolved. It would make much more sense to consolidate this bug (and it’s votes) with the similar ones and to either mark it as “in progress” if a solution was planned or “rejected” if the bug was not going to be fixed.
ABRP knows how to calculate alternate routes, and even to label them with at least the time delta or something like “saves energy.” At the very least it seems like these kind of route optimizations could be marked as alternate routes with a label like “traffic jam: -3 min” or something like that.
Would it not be possible to detect these by comparing the old route with the new and noticing that you return to the old route in short order with no intervening reason for the deviation?
In the US, at least, ABRP does not have good enough traffic information to make these kind of routing decisions. I have often been directed to do a maneuver like this where there was in fact a traffic jam on the exit and when I got back on the highway I was actually behind the vehicles that just continued on the highway.
