Crossing vehicle guide sign device of blocked roads and control method and application thereof

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...

Problems solved by technology

[0008] The object of the present invention is to provide a vehicle guidance and marking device at crossings of closed roads to solve the problems of reliable and effective control, guidance and management of traffic flow at crossings of closed roads, especially to solve the problem of signal at crossings and crossings of closed expressways in cities. The waste of device resource utilization also reduces the cost of expressway construction, reduces the difficulty of driving at the ramp of the expressway, improves the traffic efficiency and safety factor of the expressway, and can meet the requirements of closed roads. Actual requirements for traffic management at crossings, especially at crossings of urban closed expressways where the main road and auxiliary roads are at the same level
