Double lane-changing T-type intersection design plan

Abstract

The invention relates to a double lane-changing T-type intersection design plan. The double lane-changing T-type intersection design plan is a traffic organization design and a traffic control method which can increase traffic capacity at the intersection, reduce delay at the intersection and increase safety of pedestrians and non-motor vehicles, and belongs to the field of traffic design and traffic control. The method enables a main road to change the lane in the intersection through intersection lane-changing of the main road, moves go-straight and left-turn conflict points outwards, allows left-turn traffic volume having no delay within the intersection range, and changes original three-phase control into two-phase control, thereby greatly reducing a signal timing period, being beneficial to implement signal and coordination control at two conflict points, realizing green wave traffic and guaranteeing left-turn demand of the arterial road and branch road and fluency of road traffic.

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. Because the traffic in al...

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
