Tunnel extrapolation [PATCH]

Reported by: korrosa Owned by: cp15
Priority: major Milestone: version 0.5.2
Component: mapdrivers/OSM Version: git master
Severity: normal Keywords: tunnel, underground
Cc:

Description

The patch attached adds the required functionality to be able to use tunnel extrapolation. Patch is from http://wiki.navit-project.org/index.php/Tunnel_Extrapolation

Once applied you will need to do two things:

1) Inside the <tracking ... > tag add tunnel_extrapolation="12". The value 12 = number of tenths of a second extrapolation per gps rate. You'll probably need to play with this number.

2) Re-process the OSM data with maptool to create a new binfile.

...and ensure that the tunnel in OSM has tunnel=yes set!

Note: This does not seem to work out in the field. I personally haven't tested it - just copying over from the wiki page so others could patch and comment in a more structured way...

Tried it on various releases (the last being r5333) and the cursor freezes as soon as I enter the tunnel, despite the road having the correct attributes.

What exactly does the tunnel_extrapolation="12" do? I didn't quite understand it from the description. Any suggestions to how I might tweak this number to make it work?

  • Component changed from core to mapdrivers/OSM
  • Keywords underground added
  • Milestone set to version 0.5.1
  • Owner changed from KaZeR to cp15

So this patch needs further work on.

P.S. From a designers POV, I request #1136 (fixing alpha) to represent tunnels in a soft style.

As it seem to be on the way, I schedule it for the next hotfix already.

  • Severity set to normal

Please have a look at http://trac.navit-project.org/ticket/1232, if this might be a viable solution.

That sounds like a plan. I'd say put this one on hold, go ahead with #1232 and then see if there's anything left to do about tunnel extrapolation.
