Difficult turn
Remove the caustion

As of May 2016[update], the difficult turn box is a 24 hour every day setting and not related to any other time-based restriction. That may be something available in the future but not at this time. |
Add Consult with your State Manager to see if there is any criteria for when to add a difficult turn. Overuse of difficult turns will significantly affect routing. Entering difficult turns on every left turn along a stretch of the road negates the attribute's intention since all have the same penalty. This would either cause a much long route to have several right turns around an area to come back to the destination or have it so that each turn is equally penalized which is the same as no turns being penalized.
Some regions or states may even have typical times for difficult turns to be added during rush hour, that may be similar a locality's no turn restrictions.
Adding/editing a difficult turn
Difficult turns are recognizable by the lined shading on either allowable turn restrictions (green TRs) or time based turn restrictions (yellow TRs). To add a difficult turn restriction:
- Hover over any green or yellow turn restriction for the first turn interface pop up (gray box) to appear
- Select the DIFFICULT TURN's Yes attribute
- If it is not desired to have a 24/7 penalty applied for the difficult turn, then click the white clock icon to the right of Yes
- The second turn interface pop up (Edit restrictios) to appear
- Add the time, day, or date restriction similar to the TBTR instructions above
- If there is already a restriction either
- Click the Add new radio button to add another restriction
- Click the > at the right of the existing restriction line to modify the current restriction
- Click the trashcan to delete the current restriction (just to the left of the > when you hover over the area)
