Tails in roundtrips

Hi all!

I’ve been experimenting with the roundtrip algorithm, which I really enjoy. There is only 1 thing which I cannot get rid off. I get really weird “tails” in my roundtrips.

If I zoom in,

I’m trying to understand the problem here. It looks like the end of those tails are the “generatedPoints”. The algorithm tries to calculate a path till that point. And than starts calculating the path to the next generatedPoint, which causes the route to go back on the same path.

This is my config.yml:

Any ideas on how I can get rid of these? In almost every roundtrip that I generate, I have those tails :anguished:.

Looking forward to your answers!


Currently there is no setting that you can use to improve this. However, you could try changing this line in RoundTripRouting.java:


Maybe try setting the factor to 10 or so. A higher value means that it will be less likely that the round trip visits the same road multiple times (and does some detour instead).

Thanks for the help! Will try that out :grin:.

The problem still exists after changing the penalty from 5 to 10 or higher.
