Abstract

The utility model relates to an urban road network, which is arranged based on the existing checkerboard urban road, namely an ordinary road. Unidirectional quick roads and ordinary roads are interwoven vertically and transversely and are arranged at intervals. Unidirectional quick overpasses are arranged at the intersection positions between the unidirectional quick roads and the ordinary roads. The urban road network aims at improving traffic capacity of the urban roads through the unidirectional quick roads and the unidirectional quick overpasses so as to diverge traffic pressure of other roads, resolve a problem of urban congestion, and bring convenience to trips of people. The urban road network is characterized in that a nearby unidirectional quick road can be found to realize rapid transit when goes to destinations in any direction, and users can choose the closest road to run to achieve the purpose of saving gas. Adjacent unidirectional quick roads have the traffic capacity of expressways and have various functions of the urban roads simultaneously, thereby being a perfect combination of the expressways and the ordinary roads. The urban road network can be rebuilt based on the existing roads, is small in investment, simple in construction and easy to put into operation, covers small area, and has more complete functions than the expressways.

The purpose of this utility model is to provide a kind of improvement project---a kind of urban road network of optimal design of urban traffic.

The purpose of this utility model is achieved through the following technical solutions.

A kind of urban road network, be that existing urban road based on checkerboard is an ordinary road and being provided with, it comprises unidirectional express way, is divided into vertical express way and horizontal express way again, and unidirectional express way and ordinary road are interweaved in length and breadth, are provided with at interval.

Described unidirectional express way is provided with three above principal direction direct lanes, a left turn lane, a right-turn lane, and the contrary principal direction track of 1-2 bar; The contrary each other direction of adjacent unidirectional express way.

Intersection location in unidirectional express way and ordinary road is provided with unidirectional quick overpass bridge.

Interchange can be adopted in the intersection of vertical express way in the unidirectional express way and horizontal express way.

Described unidirectional quick overpass bridge is divided into upper and lower two-layerly, and the upper strata of overpass bridge is provided with three above direct lanes and a left turn lane, and the lower floor of overpass bridge is provided with two direct lanes, a left turn lane and three right-turn lanes.

The utility model has solved the urban road network existing road brings traffic jam, one-way trip inconvenience and sky way more because of traffic lights deficiency.The utility model tries hard to improve by unidirectional express way and unidirectional quick grade separation the traffic capacity of urban road, to shunt the traffic pressure of other roads, solves the difficult problem that urban traffic is stopped up, the facility that provides the people to go on a journey.Be characterized in: the target to any direction is advanced, and all can find unidirectional express way to realize rapid transit nearby, also can select nearest road driving to reach fuel-efficient purpose.The adjacent one-way express way has the traffic capacity of speedway, possesses every function of urban road simultaneously again, is the perfect adaptation of speedway and ordinary road.The utility model can be reconstructed on existing road, has small investment, floor space is few, engineering is simple, and is easy to implement, but has the function more complete than speedway.

Description of drawings

Fig. 1 is the schematic diagram of urban road network of the present utility model;

Fig. 2 is the schematic diagram of unidirectional quick overpass bridge.
