Are contours allowed to intersect other TNM objects?
While contour zones can intersect other TNM objects, users should be advised not to intersect or encompass roadways and barriers with contour zones, because contouring logic can break down in areas of steep noise gradients, such as near the ends of barriers. Furthermore, users should avoid encompassing an entire TNM run with a contour zone. To compute a contour zone about a barrier/roadway, create a contour zone in front of the barrier/roadway and behind the barrier/roadway.
