Humanized multifunctional intersection for urban crossroad

Abstract

The invention discloses a humanized multifunctional cloverleaf junction for a urban crossroad. Ramps and viaducts are built and erected in sequence or on different divided lanes or by other ways, mainly according to different running directions of the vehicles. The crossing of the vehicles at the crossroad is realized in a way that the vehicles preferentially run upwards and downwards the viaducts; i.e. the vehicles running on the road in different directions can complete all crossings at the crossroad by themselves during the driving process; simultaneously, the cloverleaf junction is provided with a platform and a stair leading to the ground road; furthermore, vehicle travelling routes of different directions are isolatedly arranged by the platform and the road fences, thus overcoming the problems of turning of vehicles running in different directions at the center of the crossroad and the parking of the buses; the design of the cloverleaf junction facilitates the passerby to transfer buses; the ground road of the crossroad is kept for passerby, non-motor vehicles, establishing of parking sites and the like; furthermore, the crossroad cloverleaf junction has the function of transfer center of small passenger transport. The humanized multifunctional cloverleaf junction takes the human as the basis and carries out the creative design, solves plenty of problems that the current cloverleaf junction at the crossroad of the city occupys large land and has complex structure, and can not be compatible with the passerby and non-motor vehicles and the like, saves a large amount of money used for construction and removal, and effectively utilizes the land resources of the crossroad and the road.

Description

(1) Technical field: [0001] The invention relates to the field of road design or layout, in particular to a new technical solution in the field of overpass lane lines and platform design or layout at road intersections. The present invention is referred to as urban crossroad humanized multifunctional overpass. (two) background technology: [0002] With the rapid development of the modern economy, our country has entered the era when individuals use cars instead of vehicles. In order to alleviate the sharp increase of vehicles in the city, the government generally uses a large number of demolition and relocation to widen roads and form a road network. However, intersection points of the road network, such as crossroads, are often the bottleneck of urban traffic congestion. If the traditional traffic light control method is adopted, traffic light control itself has become one of the sources of traffic congestion; therefore, urban intersections are becoming more and more popular...

AI Technical Summary

Problems solved by technology

[0006] The technical scheme of the fully interoperable pedestrian-vehicle lane separation on the second floor is to lead the left-turn lane in the fourth road to the outermost lane on the left with a flyover bridge, and reach the exit section of the other axis of the flyover bridge. The road for passing vehicles is made of sidewalks and pedestrian bridges. Although the pedestrian three-dimensional passage has been realized, the construction cost of the overpass has also been improved, and it has also caused great obstacles to the passage of non-motorized vehicles; in addition, the diversion of vehicle traffic on the overpass Limited speed, prone to blockage

[0007] Such interchange bridges have something in common from the structure of the bridges. The overpasses are two floors, and the intersection points of the driving routes are too concentrated at the crossroads, so there is a phenomenon that the vehicle diversion is slow and easy to block; at the same time, the station platform The installation is far away from the intersection, and there are many disadvantages such as inconvenience for pedestrians to pass through the intersection, transfer, and take a bus; in addition, the overpass occupies a large area in the center of the intersection, the structure is complex, the amount of engineering is large, and the land utilization rate of the road is low

The main reason for the above problems is that most of the traditional overpasses take how motor vehicles pass through the intersection as the main design object, and lack of design thinking on how to take into account pedestrians and non-motorized vehicles passing through the intersection. The goal of green environmental protection and sustainable development is not compatible
