Embodiment
The technical solution in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment be only a part of embodiment of the utility model, rather than whole embodiment.Based on the utility model
In embodiment, all other implementation that those of ordinary skill in the art are obtained without creative efforts
Mode, shall fall within the protection scope of the present invention.
The utility model provides a kind of city expressway and enters ring road flexibility inducible system.Referring to Fig. 1, the city is fast
Fast road, which enters ring road flexibility inducible system, to be included into ring road detector 1, main road upstream detector 2, main road downstream sensors 3, enters circle
Road LED display 4, main road LED display 5 and processor 6.It is described enter ring road detector 1, main road upstream detector 2, main
Road downstream sensors 3, enter ring road LED display 4 and main road LED display 5 is connected with processor 6 by signal wire.Such as
Shown in Fig. 1, the section that conflicts will be defined as with the section that ring road converges on main road.The meet of ring road and main road is defined as converging
Point.
It is described enter separately 20 meters~100 meters of ring road detector 1 and point.It is described enter ring road detector 1 be embedded in circle
Road.It is described enter ring road detector 1 be used to detecting vehicle on ring road and reach situation.
Imported with the vehicle on ring road from the point of view of the direction of main road, it is described enter ring road LED display 4 positioned at it is described enter ring road visit
Survey after device 1.It is described enter ring road LED display 4 be used for show two induction informations, be respectively " can accelerate to pass through ", " slow down see
Examine and pass through ".
Main road upstream detector 2 and main road downstream sensors 3 are embedded in upstream and the main road of main road respectively
Downstream.Main road upstream detector 2 and main road downstream sensors 3 detect in the conflict section shown in Fig. 1 whether there is vehicle.
From the point of view of the direction travelled with vehicle on main road, the main road LED display 5 is located at main road upstream detector 2
Afterwards, before point.The main road LED display 5 is used to show two induction informations, is respectively that " ring road entrance please don't add
Speed ", " front ring road imports, Reduced Speed Now ".
The processor 6 is detected according to ring road detector 1, main road upstream detector 2, main road downstream sensors 3 are entered
Vehicle condition and to it is described enter ring road LED display 4 and the induction information shown by main road LED display 5 controlled in real time
System.The setting position of the processor 6 is unlimited, can be in the side of ring road or main road.
It is described enter ring road LED display 4 placed respectively with proper angle with main road LED display 5, in order to avoid driver's mistake
Receive information.
Preferably, the distance between main road upstream detector 2 and point are more than into ring road detector 1 and point
The distance between, to ensure that " front ring road imports the information shown on main road LED display 5 is received of vehicle on main road, subtracts
After speed traveling ", speed-down action can be made in time, thus ensure point between main road downstream sensors 3 without vehicle, so as to
Main road can be imported in the vehicle for entering ring road.

Member's garbled-reception induction information.
The course of work that the city expressway enters ring road flexibility inducible system is as follows：
When it is described enter ring road detector 1 be not detected by vehicle when, on Entrance ramp LED display 4 display " can accelerate to lead to
Cross " this induction information, while " ring road entrance, please don't accelerate " this induction information is shown on main road LED display 5.
When it is described enter ring road detector 1 detect vehicle, processor 6 is according to main road upstream detector 2, main road downstream vehicle
When vehicle condition that detector 3 is detected judges conflict section without vehicle, it is described enter ring road LED display 4 on show and " can accelerate
Pass through " this induction information, " ring road entrance, please don't accelerate " this induction information is shown on main road LED display 5.So as to enter
Ring road vehicle can be higher speed import main road, produce that delay is small, and traffic efficiency is high.
When it is described enter ring road detector 1 detect vehicle, processor 6 is according to main road upstream detector 2, main road downstream vehicle
When vehicle condition that detector 3 is detected judges that there is vehicle in conflict section, it is described enter ring road LED display 4 on display " slow down and see
Examine and pass through " this induction information, display " ring road vehicle imports, Reduced Speed Now " this induction information on main road LED display 5,
In order to which the vehicle deceleration on ring road imports main road, while the vehicle of main road upstream reduces speed now, and reserving to make on ring road
Vehicle safety imports the space headway of main road.After vehicle safety remittance main road on ring road (such as after 5s), enter ring road LED
Display screen 4 shows " ring road entrance, please don't accelerate " this induction information, and main road LED display 5 shows that " front ring road, please don't add
This induction information of speed ".
