The correct answer is: A. number of intersecting roads is between 4 and 7.<\/p>\n
A traffic rotary is a type of intersection in which traffic flows in a circular pattern around a central island. They are often used in areas with high traffic volumes, as they can help to improve traffic flow and reduce congestion.<\/p>\n
Traffic rotaries are typically justified when the number of intersecting roads is between 4 and 7. This is because rotaries are most efficient when there are a moderate number of roads converging at a single point. If there are too few roads, a rotary may not be necessary, as traffic can be easily managed with stop signs or traffic lights. If there are too many roads, a rotary may become too congested, and it may be more efficient to use a different type of intersection, such as a signalized intersection.<\/p>\n
Options B and C are incorrect because rotaries can be used in areas with limited space or high traffic volumes. Option D is incorrect because rotaries are typically used in areas with moderate traffic volumes.<\/p>\n","protected":false},"excerpt":{"rendered":"
