Rapid cross overpass

Abstract

The invention provides a rapid cross overpass. The rapid cross overpass is characterized in that an east-west bridge arranged above the middle part of a road and a north-south bridge arranged above the middle part of another road form a cross above a crossroad, so vehicles can straightly move eastwards, westwards, northwards and southwards; vehicles can normally run on four U-turn lanes, four right-turn lanes and two left-turn lanes as before; and only the rest two left-turn lanes are arranged at below slopes formed by the bridges, i.e., AB and CD under-overpass left-turn lanes. Through arrangement of the rapid cross overpass, four original lanes at the crossroad are unblocked; EF, GH, IJ and KL under-overpass passages are changed to positions as shown in the specification, so the height of the under-overpass left-turn lanes is greatly reduced; through arrangement of the under-overpass passages, pedestrians and non-motors can safely and rapidly pass through the roads; intersections of the under-overpass passages, sidewalks and non-motor lanes are provided with deceleration strips to guarantee safety of pedestrians; and distance between bridge piers at places for U turn, left turn and right turn is too small, and bridge piers at the crossroad are moved backward a little bit.

Description

technical field [0001] The invention belongs to the technical field of road traffic, in particular to the technical field of overpasses. Background technique [0002] Existing inventions and utility model patents do not solve the worldwide traffic congestion. According to the normal driving rules of vehicles, the width of the road at the intersection should meet the requirements of four lanes at least. Pedestrians and non-motor vehicles cross the road slowly and unsafely. , The underground left-turn lane of the cross overpass has a large slope and a deep downward driving depth, and the distance between the pier and the pier at the U-turn, left turn, and right turn cannot be applied to an intersection with only four lanes wide.

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above-mentioned technical deficiencies, the present invention provides a fast cross overpass, the underground left-turn lane is arranged under the ramp, which effectively solves the problem that the overpass bridge occupies a wide area, and also solves the problem that the underground left-turn lane occupies a long area. The problem, of course, this underground left-turn lane also occupies a little ramp land during the downhill and uphill processes. The underground passage at the intersection (formerly E, G, now GH, KL) GH, KL is set underground on the left side of the middle position under the bridge ramp in the north-south direction, and the intersection underground passage (formerly F, H is now EF, IJ) EF and IJ are set underground on the right side of the east-west bridge without going uphill. This setting just avoids the impact on the underground lane. The distance between the pier and the pier at the U-turn, left turn, and right turn cannot be applied to only four lanes wide. Therefore, it is set to move the pier of the bridge a little distance to the rear to meet the needs of vehicles. The use of underground passages solves the problems of pedestrians and non-motorized vehicles, unsafe and slow crossing roads. Underground Deceleration belts are set at the intersections of passageway entrances and exits, sidewalks, and non-motorized vehicle lanes to slow down non-motorized vehicles to ensure the safety of pedestrians.
