Embodiment 1

[0060] The crossing vehicle guidance and identification device for closed roads includes a first judgment module 1, a first control module 2, a second control module 3 and a display module, and the first judgment module 1 is connected with the first control module 2 and the second control module respectively. 3, the first control module 2 and the second control module 3 are respectively connected to the display module; the display module adopts LED display elements 4, and the LED display elements 4 include exit signs and entrance signs Two display working states; the first judging module 1 is used to judge whether the main road 12 is in a congested state; the first control module 2 is used to judge whether the main road 12 is When in a congested state, its control turns on the display working state of the LED display element 4 being in the exit sign; the second control module 3 is used for if the first judging module 1 does not judge that the main road 12 is in a congested stat...

Embodiment 2

[0062] The crossing vehicle guide sign device of closed road, with embodiment 1, difference is, as image 3 As shown, the crossing vehicle guidance identification device also includes a second judging module 6 connected to the first judging module 1 through a comparator 5, and the second judging module 6 is also connected to the second control module 3; The second judging module 6 is used to judge whether the auxiliary road 13 is in a congested state, and compares its judging result with the result of the first judging module 1 to the congested degree of the main road 12 by the comparator 5; the second control module 3 For if the comparator 5 judges that the auxiliary road 13 is in a more congested state than the main road 12, and if the LED display element 4 is in the display working state of the exit sign at this time, it controls to turn on the LED The display element 4 is in the active state of displaying the entrance sign.

Embodiment 3

[0064] The crossing vehicle guidance marking device of a closed road is the same as that in Embodiment 1, the difference is that the display working state of the exit sign of the LED display element 4 adopts the inverted triangle mark 7 of the auxiliary road, and the inverted triangle mark 7 of the auxiliary road is used. The hypotenuse is set along the direction from the main road 12 to the side road 13, and one right-angled edge of the side road to the inverted triangle mark 7 is set along the direction of the side road 13, and the other right-angle side is set along the direction perpendicular to the side road 13.

Abstract

The invention relates to a crossing vehicle guide sign device of blocked roads and a control method and application thereof. The crossing vehicle guide sign device comprises a first judgment module, a first control module, a second control module and a display module. The first judgment module is connected with the first control module and the second control module respectively; and the first control module and the second control module are respectively connected with the display module. A light emitting diode (LED) display element is adopted for the display module and has two working states, namely driving-out port marking and driving-in port marking. The control method of the crossing vehicle guide sign device is used for controlling changing states of the changeable sign device located at crossings of the express way. By adopting the crossing vehicle guide sign device of blocked roads and the control method and application thereof, reliable and effective control, directing and management for traffic flow at the crossings of the express way can be achieved, the problem of resource utilization waste of the crossings of the express way and signal devices at the crossings can be solved, express way construction cost is reduced, driving operation difficulty of drivers at the crossings of the express way is reduced, and express way traffic efficiency and safety coefficient are improved.

Description

technical field [0001] The invention belongs to the technical field of traffic signal control, and relates to a crossing marking device and its use method and application, in particular to a crossing vehicle guidance marking device for urban closed roads and its control method and application. Background technique [0002] Entrances and exits of closed roads can be divided into two types, one that guides the entry or exit of vehicles through fixed objects, such as guardrails or pavement bricks, and the other that is only guided by ground markings. Neither the former nor the latter are interchangeable as ingress or egress. That is, an exit is always an exit, and an entrance is always an entrance. [0003] A road situation that often occurs is, for example, at the entrance of a closed road section, there is a traffic jam on the closed road section, and there are very few vehicles on the adjacent side road on the outside. Because this crossing is a driving entrance, so the ca...
