Scheme for designing plane T-shaped intersection through main road lane changing

Abstract

The invention discloses a scheme for designing a plane T-shaped intersection through main road lane changing, relates to a traffic organization design and traffic control method and belongs to the field of traffic design and traffic control. According to the traffic organization design and traffic control method, the intersection capacity is improved and intersection delay is reduced; meanwhile, safety of pedestrians and non-motor vehicles is improved. According to the method, intersecting lane changing is carried out on a main road in the intersection through main road intersecting, and straight and left turning conflict points are moved outwards; the left turning traffic volume is free of delay within the range of the intersection. Meanwhile, original three-phase control is changed into two-phase control, and the period of signal timing is greatly reduced. The signal and coordination control over the two conflict positions can be easily implemented, and green wave traffic is achieved. The demanded quantity of left turning of a primary road and branch roads and smooth road passage can be achieved.

Description

technical field [0001] The invention relates to a traffic organization and channelization method for improving the traffic capacity of urban road intersections, belonging to the field of traffic design and traffic control. Background technique [0002] With the development of cities, the density of urban road networks is increasing, and people's demand for traffic is also increasing. Urban road construction can no longer meet people's needs, so the organization and management of road networks is particularly important. Before proposing the new organizational scheme design of the T-shaped intersection, we still take the principle of improving the traffic capacity of the intersection. In the urban road network, the intersection node is often the bottleneck of traffic flow, and it is the main point causing traffic delay. According to statistics, in the urban road network, the delay time of vehicles at intersections accounts for 30% of the whole time. At the intersection, traf...

Problems solved by technology

The former solution is to deal with left-turn conflicts by adding dedicated left-turn phases. Although this method solves the conflicts, there is a loss of signal time, but it leads to an increase in the delay time at the intersection and greatly reduces the traffic capacity of the intersection.

Another solution is that when high-grade roads and low-grade roads intersect, low-grade roads use right-in and right-out, and left-turns are realized by turning around through road sections. This scheme prohibits vehicles on the main road from turning left to low-grade On the road, the accessibility of the road cannot be satisfied, which affects the travel of surrounding residents
