TRAFFIC GUIDE CONSTRUCTIONS AT ROAD INTERSECTIONS TO PROVIDE SMOOTH TRAFFIC FLOWS AND METHODS OF TRAFFIC CONTROL THEREOF

摘要

Traffic guide constructions at road intersections to provide smooth trafficflowsthereof and the methods of traffic control with these traffic guideconstructions, Theconstructions mainly include overhead bridges and/or underground tunnelsextendingin parallel to a main road and one or more branch road intersecting with themain roadto cross the intersections thereof so as to avoid traffic jams thereat. Carsmay move onthe main and the branch roads straight forward without being interrupted attheintersections. Cars moving on the main and the branch roads can make turns toeithersides by using the tunnels under the overhead bridges or the turnarounds abovetheunderground tunnels to avoid interfering with the cars moving straight forwardandcausing any traffic jams at the intersections. Such traffic guideconstructions at roadintersections do not need spacious land nor will them be affected by buildingsaroundthe intersections and are therefore suitable for different topographies andspaces toprovide smooth traffic flows.
