Problems solved by technology

[0004] If the above-mentioned areas are conventional urban residential areas or office areas, such a grid-shaped urban road network can generally carry and adapt to the traffic demand of the area; but if these areas are high-intensity developed commercial office areas (such as more than 3, and more than 80,000 jobs per square kilometer), this kind of grid-shaped urban road network cannot meet the traffic demand generated by high-intensity development due to the restriction of the traffic capacity of a large number of plane intersections. For traffic congestion, frequent parking, long vehicle queuing distance, long travel time, low traffic efficiency, and low service level

Embodiment Construction

[0012] An important feature of the road network system provided by the present invention is the one-way traffic lane at the grade intersection. If adopt the two-way driving lane of level intersection, just there will be many problems. The four-cross interchange type overpass is a typical three-dimensional intersection mode of existing two-way driving lanes. Since both the transverse lane and the longitudinal lane are two-way driving lanes, it is very complicated to perform intercommunication at the intersection of the transverse lane and the longitudinal lane. Because both the horizontal lane and the longitudinal lane have two directions, there will be 8 situations for their intercommunication, that is, east-west turns to north-south, east-west turns to north-south, west-east turns to north-south, and west-east turns to north-south direction, north-south to east-west, north-south to west-east, north-south to east-west, north-south to west-east, therefore, 8 corresponding conn...

Abstract

The invention discloses a road network system, comprising a plurality of one-way traffic lanes, wherein every two one-way traffic lanes are crossed in a vertical crossing way. The road network system provided by the invention adopts the one-way traffic lanes which are vertically crossed, thus a continuous flow all-stereoscopic road network system is formed. When the road network system provided by the invention is applied to urban transportation, the problem of traffic jam caused by grade crossing can be avoided.

Description

technical field [0001] The invention relates to a road system, in particular to a road network system of a three-dimensional intersection. Background technique [0002] With the high-intensity development of urban land and the sharp increase in car ownership, road traffic congestion has become a common urban problem and a constraint on further urban development. Today, large and medium-sized cities are congested, and traffic flow regulation is one of the important topics in road traffic research in various countries, and traffic regulation at intersections is the key to solving the problem of road traffic congestion. [0003] At present, urban areas generally adopt a grid-shaped road network, and road levels include primary and secondary arterial roads and branch roads. The distance between main roads is 1.5-2 kilometers, the distance between secondary roads is 500-900 meters, and the distance between branch roads is 150-300 meters. At the intersection of the main road and...
