The purpose of this article is to prevent dangers to persons and property, to prevent delays and to avoid interference with the traffic flow. Roadways that have center medians often are designed to deal with specific traffic flow problems. Any delay or distraction may interfere with traffic planning. Sometimes persons stand near intersections and near traffic lights to contact drivers or passengers in cars that are passing or that are stopped temporarily due to traffic lights or traffic flow.
