Expressway hard shoulder dynamic adjustment system and method thereof

Abstract

The invention relates to an expressway hard shoulder dynamic adjustment system and a method thereof. The system comprises a traffic detection unit, a control decision-making unit and an information issuing and diversion unit which are connected in sequence, and the traffic detection unit is used for sensing traffic operation data and traffic state information in a current road section in real time. The control decision-making unit analyzes the state information of each lane of the current road section according to the data information collected by the traffic detection unit, judges whether a hard road shoulder of the current road section opens a traffic lane function, and carries out speed limiting management on each lane of the current road section. The information issuing and diversion unit is used for displaying the state information of each lane of the current road section and traffic control information. Compared with the prior art, the hard road shoulder can be dynamically opened / closed, and the space of the hard road shoulder is fully utilized to be used as a roadway, so that the traffic capacity and the driving safety of an expressway are improved, the traffic jam time is shortened, the accident rate is reduced, automobile exhaust emission and fuel consumption are reduced, and investment and land resources are saved.

Description

technical field [0001] The invention relates to the technical field of traffic management and control, in particular to a dynamic adjustment system and method for a hard shoulder of an expressway. Background technique [0002] Hard shoulder (Paved Shoulder) refers to the shoulder part (including the curb belt) adjacent to the roadway and paved with a certain strength pavement structure. The "hard shoulder" is a lane drawn with a solid line on the right side of the expressway. Its main function is to provide emergency parking for breakdown vehicles or as a temporary emergency passage. Except for special vehicles or special circumstances, other vehicles are not allowed to enter or park during normal hours. The single traffic function and management method of the hard shoulder is likely to cause vacancy and waste of road space, which restricts the traffic capacity of the road and leads to expressway peaks. Traffic congestion is getting worse. [0003] In order to alleviate th...

Problems solved by technology

Except for special vehicles or special circumstances, other vehicles are not allowed to enter or park during normal hours. The single traffic function and management method of hard shoulders is likely to cause vacancy and waste of road space, which restricts the traffic capacity of the road and leads to expressway peaks. Traffic congestion is getting worse

[0003] In order to alleviate the increasingly serious congestion of expressways, at present, most of them will adopt the method of demonstration first and expansion later, that is, one or more lanes will be widened in one direction on the basis of the existing lanes, but this method will undoubtedly require high land acquisition , demolition and project investment

Moreover, the more lanes are widened, the higher the cost, which is very unfavorable for the intensive use of land
