Problems solved by technology

Because the intersection has only one left-turn lane, and the entrance lane and exit lane of the main road have three lanes, so when the control signal light is the first phase, often the left-turn traffic flow of the intersection only needs one exit receiving lane, and the exit lane is different from the exit lane. The entrance through lanes of the main road corresponding to the main road are all waiting for the red light, which causes a waste of road resources and reduces the traffic capacity of the main road. Therefore, it is necessary to improve the traffic control method of the traditional T-shaped intersection

Embodiment 1

[0019] like figure 2 Shown is a T-shaped intersection without a sidewalk on the main road. The main road of this T-shaped intersection has six lanes, and the intersection has four lanes. Set up a 50-meter-long lane separation road surface solid line marking 150 meters upstream of the intersection on the outer side of the road to separate the two through lanes on the outside of the main road. It is recommended that vehicles cannot change lanes. Set 50 meters behind the solid line marking The physical lanes with a length of one meter and widening divide the road markings, and vehicles are prohibited from changing lanes. Then, a 50-centimeter-wide benchmark is set 50 meters upstream of the intersection, and a symmetrical 50-meter-long and 50-centimeter-wide steel benchmark, 50-meter-long, is also set downstream. Widened solid lane dividing pavement markings and 50-meter-long lane dividing pavement dashed line markings.

Embodiment 2

[0022] In view of the need for pedestrians to cross the main road at most urban intersections in our country, if the pedestrians who need to cross the main road at the T-shaped intersection cannot be transferred to other pedestrian crossing facilities upstream or downstream, the design and control of the T-shaped intersection must be carried out. The phasing takes into account the need for pedestrians to cross arterial roads. like image 3 As shown, compared with Embodiment 1, this embodiment is except that the main road is also equipped with sidewalks, the benchmark pole between the straight-going area and the left-turn area is up to one meter wide, and the peripheral protective piles are set in the stagnation area of ​​the pedestrian crossing the main road. , the rest of the facilities and layout are completely consistent with the T-shaped intersection in Embodiment 1. In this embodiment, a sensor button device for pedestrians crossing the main road can be installed at the ...

Embodiment 3

[0024] like Figure 4 As shown, compared with Embodiment 1, this embodiment separates all the three through lanes on the outside of the main road, and develops a left-turn exit on the central divider at the downstream of the outside of the main road in the driving direction. , there is also a solid left-turn traffic guidance central safety island in the center of the T-shaped intersection, and the widened signposts and physical lane separation road surface markings in the upstream and downstream directions on the outside of the main road can be reduced to 10 meters long, while the downstream Change the solid line markings on the lane separation road surface to dotted lines and set the road surface arrows merging from the inside to the outside to guide vehicles merging from the inside to the outside. Other than that, the other structures and layouts are consistent with the embodiment, and the traffic control phase of this embodiment is also consistent with the first embodiment....

Abstract

The invention discloses a traffic control method of a T-shaped road crossing. The T-shaped road crossing comprises a main road and a crossing road and is characterized in that a section of separating device is arranged on a driveway in the traffic direction at the outside of the main road, the driveway at the outside of the main road is separated into two parts: a straight-through area and a left-turn area, so that the straight-through area sustains continuous traffic status to ease vehicle delay at the road crossing. In the invention, the vehicle delay at the crossing can be eased and traffic capacity of the T-shaped road crossing can be improved by 30% so long as the T-shaped road crossing is slightly changed; in addition, the method of the invention features economy, environmental protection and considerable energy conservation effect.

Description

technical field [0001] The invention relates to the technical field of traffic control at road intersections, in particular to a traffic control method for T-shaped intersections. Background technique [0002] After entering the 21st century, my country's economy has maintained rapid growth, urbanization and motorization have developed rapidly, and the number of motor vehicles and road traffic has expanded rapidly, resulting in urban traffic congestion, traffic safety, energy consumption, and environmental pollution. The problem has become an overall problem related to the sustainable development of the national economy. In the past quite a period of time, the country has invested a lot of financial and material resources in the development of infrastructure. However, the available space resources in the city are becoming more and more scarce, and the construction cost is getting higher and higher. Solving the problem of traffic congestion by building new road facilities way...
