Description
Technical Field
The invention relates to the technical field of traffic control, in particular to a turnout ramp converging control device.
Background
The road interchange converging comprises main line converging, junction ramp converging, collecting and distributing ramp converging, continuous converging and the like, and the scale and the arrangement form of the lanes are determined according to the traffic volume and the principle of balancing the number of lanes and the traffic capacity, so that once the predicted annual traffic volume is determined, the scale and the geometric dimension of the section of the lanes at the upstream and downstream of the road interchange converging are basically fixed, and the road interchange converging is embodied through ground marking.
However, in the actual running of the road, various working conditions such as peak/flat running, traffic accidents, emergency situations and the like exist, and meanwhile, the predicted traffic volume and the actual traffic volume tend to generate differences, so that the consistent scale of the upstream and downstream roads is obviously difficult to adapt to the specific requirements under the specific conditions, and the inadaptation can be mainly reflected in different requirements on the scale of lanes of the two upstream ramps and the scale of the total lanes of the main line downstream after the two upstream ramps are merged.
Meanwhile, under the condition of limited construction space, the traffic organization and the lane scale of the upstream and downstream roads are coordinated, so that the situation of dilemma often occurs, and the two aspects cannot be realized at the same time.
If the traffic flow distribution condition of the upstream road is combined with the real-time traffic flow distribution condition of the upstream road by arranging the turnout type variable marking system in the merging region according to different working conditions and actual traffic demands, the lane scale of the upstream road which is connected into the merging region can be dynamically adjusted, so that the problems can be effectively solved.
For such a case of temporarily adjusting the lane scale, a measure of providing a temporary partition is currently adopted, and this method has the following drawbacks:
1. the treatment and adjustment are dependent on manual work, the response speed is low, the first time adjustment can not be realized, the flexibility is insufficient, and secondary interference can exist;
2. the physical separator has hidden danger to driving safety;
3. the setting of separator and enclosing the fender needs to consume the manpower, and has the potential safety hazard to constructor.
Therefore, how to dynamically manage the road marking and allocate the resource allocation of the upstream access lane according to the traffic operation according to different working conditions becomes a technical problem which needs to be solved by the skilled in the art.

Detailed Description
Examples
As shown in fig. 1 to 9, the switch-type ramp converging control device is arranged on a section where two or more upstream ramps merge into one downstream main line; and a converging transition section is arranged between the two more upstream ramps and the downstream main line.
The road condition detection system comprises a variable sign display panel, a variable marking display panel, a controller and a road condition detection device;
each upstream ramp is provided with a variable sign display plate and a variable marking display plate on each lane corresponding to the junction transition section of the vehicle;
road condition detection devices are arranged below the road surface from each upstream ramp to the downstream main line;
the road condition detection device is connected with the traffic flow information acquisition system and sends the acquired traffic flow and vehicle speed information to the traffic flow information acquisition system;
the traffic flow information acquisition system judges the change of traffic flow according to the traffic flow and the vehicle speed information, and changes the guiding marked lines and guiding arrows displayed between the corresponding upstream ramp and the converging transition section of each variable marked line display plate through the controller to distribute lanes entering the converging transition section.
In some embodiments, each variable sign display is configured to issue current information, forward mainline information, and comprehensive information for a respective ramp issued by the traffic flow information acquisition system.
In some embodiments, each variable reticle display panel includes a light panel and a built-in controller.
In some embodiments, each variable sign display panel is disposed over a lane of a respective ramp by a portal frame.
In some embodiments, the road segments of two or more upstream ramps and corresponding downstream main lines are each an elevated road, an urban expressway or a tunnel.
As shown in fig. 6 and fig. 7, in urban traffic, the flow of the interchange ramp is not uniformly distributed in time, and especially different traffic characteristics are presented in the early and late peak period, the flow peak values of the ramp a and the ramp B are not synchronous, but the total flow after the confluence is almost consistent, and due to limited land resources, the scale of a downstream lane cannot meet the requirement of the sum of the maximum scales of the two ramps at the same time.
The invention can achieve the aim of maximizing the utilization of resources by reasonably distributing the scale of the upstream ramp lanes of the merging area on the premise of meeting the respective traffic capacity of the ramp and the main line, thereby improving the engineering feasibility and the traffic adaptability.
As shown in fig. 8 and 9, in the tunnel, the size of the section has a large influence on investment, and the lane size of the downstream tunnel can only meet the traffic capacity requirement of the downstream tunnel in some cases, so that the lane size is difficult to perfectly match with the upstream lane size. If the method can dynamically control the scale of the ramp lane according to the real-time flow of the ramp and the traffic control means on the premise of meeting the basic traffic conditions of the lane, the scale of the main line engineering after confluence is reduced, the method is beneficial to saving the engineering cost and can meet the traffic demands under various traffic conditions.
The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
