[Page update] Routing penalties  Topic is solved

Postby Kartografer » Sat Jun 01, 2019 12:55 pm

Routing penalties has some very outdated information on it. I drafted a revision here, with new information on what is penalized, new information on what is prohibited, a lead section that better explains what a penalty is, a background section that gives a more inclusive history on how penalties have been used, improved links and a note about default navigation settings.

Before writing this, I got confirmation from Yigal that:
  • Penalty is indeed measured in time, not "points"
  • Hard turn restrictions are prohibited, not penalized
  • There is a penalty associated with the number and length of segments on a route
  • The exact values of penalties (and pruning thresholds for that matter) are not to be disclosed

I also got confirmation from the beta team and QA that the default setting for both Android and iOS is to avoid all unpaved roads and difficult turns.

Note that since route stitching is still not used in production routing, I kept information about how transitions from PLR and PR are penalized. Let me know if I missed anything useful about penalties. Hoping to return this page to relevance.

Your draft page says u-turn penalties are applied when segments are <16M. I thought that we had gotten more conservative and changed the wiki page on U-turns to say <14M

Preventing median U-turns link to this section
An extremely large U-turn penalty is set for a double-left or double-right turn when all three of the conditions below are met:

Three segments: The U-turn is a reversal of driving direction through three segments:
an incoming segment (A), a single median segment (B) and an outgoing segment (C).
Short median: The median segment (B) is equal to 45.93 ft (14 m) or less.
In/out parallelism: The in and out segments (A and C) are within ±5° of parallel to each other.

I don't know where that was said. My draft, as well as the original page, use the U-turn minimum template.

Am I misreading your draft? I clicked on the link in your original post and see this. https://www.screencast.com/t/CX7fJsXcTZdV

i thought the decision point for U-turns was exactly 15m and we used 14m to disallow and 16m to allow in case editors were not using a script to show exact segment length. is that correct?

From your proposal Wrong way direction through a one-way road

Can be misleading IMO. 2 segment loops could allow wrong direction of travel. Just the fact that a segment is one-way does not prevent routing.

Not sure how to reword it to reduce the misleading information.

U-turn minimum template page wrote:The gap in the two thresholds is due to metric and imperial rounding issues, so a buffer was built into this setting to prevent unexpected results

just wondering if we would be better served documenting the exact number and then explaining why 14m and 16m are used

I would not think so since the explanation explains why the built in difference.
