# On the entry and exit segments, move geometry points very close to the nodes so that at the roundabout segment, the entry and exit segment are within five degrees of parallel.
#* Do not depend upon the sum of angles between the 3 segments unless the roundabout segment is completely straight. You may create a temporary straight segment to check the angles, then undo the change.
If all three criteria are satisfied (three segments in the movement, roundabout segment length and parallelism), a large penalty will be applied to the movement into and out of the U-turn,
causing routes involving the at-grade connector to be much more likely..
This solution is only compatible with non-normal roundabout instructions, as there will be too many nodes to meet the criteria for normal instructions . It's also difficult to use where the entrance of the first road is very far away from the exit of the next road.
