An intelligent traffic guidance system and method in a construction area

Abstract

The invention discloses a construction area traffic intelligent guide system and method. The system comprises a first radar, a second radar, a third radar, a fourth radar, a fifth radar, a first variable information plate, a second variable information plate, a third variable information plate, a fourth variable information plate, a fifth variable information plate, a sixth variable information plate, a first section intelligent induction lamp, a second section intelligent induction lamp, a first wireless communication module, a second wireless communication module, a third wireless communication module, a fourth wireless communication module, a fifth wireless communication module, a sixth wireless communication module, a seventh wireless communication module, an eighth wireless communication module, a ninth wireless communication module, a tenth wireless communication module, an eleventh wireless communication module, a twelfth wireless communication module, a thirteenth wireless communication module, a centralized wireless communication module and a microprocessor. The method comprises the steps of making a microprocessor obtain a guide control strategy according to microcosmic data acquired by the first radar and transmit display information to the first variable information plate, the second variable information plate, the third variable information plate and the fourth variable information plate separately; calculating the traffic conflict severity rate according to the microcosmic data of the first radar, the second radar, the third radar, the fourth radar and the fifth radar to obtain traffic safety conditions of the first guide control area and the second guide control area and setting a proper light-emitting mode of the intelligent induction lamps; if the traffic safety conditions of the second guide control area are poor, transmitting the display information to the fifth variable information plate and the sixth variable information plate. Compared with theprior art, the traffic efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of traffic safety technology and intelligent traffic application, and in particular relates to a traffic intelligent guidance system and method in a construction area. Background technique [0002] In recent years, my country's expressways have entered the stage of simultaneous expansion, maintenance and new construction. During the reconstruction, expansion and maintenance of expressways, especially under the traffic organization of construction and opening to traffic, it will inevitably interfere with the original road traffic flow and affect normal driving. Its main manifestations are: vehicles need to complete a series of actions such as merging, merging and diverging to pass through the construction area, and there will be phenomena such as shortened time for merging and lane changing, chaotic driving environment, large speed difference, and many sudden conflicts; reconstruction and expansion During construction...

Problems solved by technology

In this system, the unreliability, imbalance, and instability of any factor may lead to various conflicts and contradictions, thus causing traffic accidents.

The road environment in the construction area is complex and very different from normal roads. If there is no relevant information to guide, it will cause the driver's stress response (stress refers to the individual non-specific reaction caused by various stress stimuli, including physiological and psychological reactions) , when the necessary visual cues are missing (such as not knowing what to do) or adverse stress responses (such as: tension, fear) occur, the driver's "perception-judgment-decision-operation" may be deviated or even completely ineffective. Improper driving behavior will occur, which will increase traffic risks and induce traffic accidents
