Description

Technical Field

[0001] The present invention belongs to the technical field of road traffic, and particularly relates to a combined ramp for a traffic hub connecting interchange and intersection. Background Art

[0002] An urban passenger transport hub is a place for passenger flow collection, distribution and transfer in the urban passenger transport system, providing lines with different traffic modes or different directions and functions of the same traffic mode. A typical passenger transport hub is as shown in Figure 1 As shown, it is usually located in the main central city of the region, providing passenger and freight transportation services for the economic development and residents' life of the region or city. Different levels and functions of passenger transport hubs should be reasonably arranged according to the characteristics of urban spatial form, passenger travel, etc. The traffic collection and distribution of the traffic hub requires the support of a backbone road network system, and the expressway is an important carrier for quickly collecting and distributing passenger traffic. The connection between the traffic hub and the expressway is realized through the setting of an interchange for traffic conversion.

[0003] The laying forms of expressways mainly include elevated expressways, ground expressways, and underground expressways. All of them can better realize the dual functions of rapid traffic and collection and distribution traffic of urban expressways, but there are great differences in the impact on the city and the environment, land occupation, and project cost. The elevated expressway has the advantages of strong traffic function, less land occupation, and reasonable project cost. Considering that the expressway connected to the traffic hub is mainly an elevated expressway, and the elevated expressway is mainly composed of an elevated main road and a ground auxiliary road, the connection between the traffic hub and the elevated expressway generally needs to be connected to both the elevated main road and the ground auxiliary road including the flat intersection. Therefore, the rapid collection and distribution system of the traffic hub generally includes elevated roads, ground roads, elevated-ground connecting roads, elevated passenger drop-off platforms, underground parking lots, ground parking lots, etc.

[0004] Generally, traffic hubs conduct traffic collection and distribution through the expressway system, and mainly set up interchanges to connect with elevated expressways. Therefore, the grade of the connecting roads of traffic hubs is generally urban expressways. According to the relevant regulations and specifications, according to the different grades and traffic natures of the intersecting roads, there are mainly three forms of interchanges: namely, hub interchanges, general interchanges, and separated interchanges. Affected by factors such as the daily passenger flow of the traffic hub, land use conditions, and linear technical standards of the road, the interchange grades applicable to the interchanges connected to elevated expressways are hub interchanges and general interchanges (separated interchanges are not applicable). The selection of the interchange should be determined according to the position and function of the interchange in the road network, the grades of the intersecting roads, the level of the traffic hub, and at the same time combined with control conditions such as traffic demand, cost, and whether the land use is restricted. Therefore, how to orderly connect the passenger drop-off platform, underground parking lot, ground parking lot of the traffic hub with the main road and auxiliary road (including the flat intersection) of the elevated expressway and avoid weaving as much as possible has become an urgent problem to be solved. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a combined ramp for a traffic hub connection interchange and intersection to solve the deficiencies in the prior art.

The downhill ramp is connected to the traffic hub platform and the ground auxiliary road of the elevated expressway. The elevated ramp is connected to the traffic hub platform and the elevated main road of the elevated expressway.

The second ground lane is connected to the underground and ground parking lots of the traffic hub, the ground road, and the ground auxiliary road of the elevated expressway. The ground auxiliary road of the elevated expressway includes a ground intersection.

[0008] For the combined ramp for a traffic hub connection interchange and intersection as described above, the lane scale of the first ground lane, the downhill ramp, the elevated ramp, the uphill ramp, and the second ground lane is all one or two one-way motor vehicle lanes.

[0009] For the combined ramp for a traffic hub connection interchange and intersection as described above, connection ramps are provided between the downhill ramp and the traffic hub platform, and between the elevated ramp and the traffic hub platform.

[0010] For the combined ramp for a traffic hub connection interchange and intersection as described above, interchange ramps are provided between the elevated ramp and the elevated main road of the elevated expressway, and between the uphill ramp and the elevated main road of the elevated expressway.

[0011] The beneficial effects of the technical solution of the present invention are:

[0012] 1. It can connect the traffic hub platform, underground parking lot, ground parking lot, and ground road, and can connect the elevated main road of the elevated expressway and the ground auxiliary road (including the ground intersection);
