Abstract

The invention discloses a road buffering island and application thereof, and belongs to the field of traffic design. The road buffering island is realized through the following technical proposal: a basic structure of the road buffering island consists of an outer ring archipelago, a four-in and four-out inner lane and an inner ring island; and the road buffering island is generally arranged in aroad central region. The road buffering island is designed and has the function of a crossing ring island; the inside of the road buffering island is also provided with a buffering passage specially for the left turn of vehicles; the buffering passage has main functions of adjusting the straight movement and the left turn of the vehicles in a crossing and the conflict between rapidness and slowness, buffering a few vehicles and dredging most vehicles and is complementary with a planar turning and returning point road unit and a vehicle shunting traffic light technology, can reduce shunting oreven has no shunting and can effectively get rid of the influence of the left-turn vehicles on the crossing, thereby relieving the phenomena of crossing congestion and p[laying important functions onimproving traffic capacity and safety level of urban roads.

Description

technical field

[0001] The invention relates to the field of traffic design, in particular to a road buffer island and its application. Background technique

[0002] At present, to control the traffic of vehicles turning left at intersections, it is generally necessary to set up special left-turn parking lanes at intersections and traffic lights and left-turn signals for separate control. It is one of the main causes of intersection congestion. With the popularization and application of the new technology of road units at plane turning points and vehicle diversion traffic lights, part of the diversion of left-turning vehicles will be carried out, and the regular waiting at intersections will be changed to rapid diversion. In the implementation, the fewer vehicles that are considered as diversion, the better. A new road buffer island design scheme is proposed, which can reduce traffic diversion or even no diversion, and can effectively get rid of the influence of left-turnin...
