Straight median segments
If the median segment is straight, sum the two angles making up the U-turn:
- The angle between the incoming and median segments (between A and B)
- The angle between the median and outgoing segments (between B and C)
The in and out segments (A and C) are considered parallel if the sum is between 175º and 185º.
The short 14m median segment in the above examples satisfies condition #2 for U-turn prevention. |
