Method for determining lengths of upstream transition regions of construction operation area

Abstract

The invention belongs to the technical field of road design, which relates to a method for determining lengths of upstream transition regions of a construction operation area. The method comprises the steps of: firstly, designing a driver SOAR (state, operator and result) intelligent agent working memory structure, secondly, designing initial long-term memory rules, and establishing a long-term memory rule base of driver SOAR intelligent agent, thirdly, establishing the decision-making period of the driver SOAR intelligent agent, fourthly, establishing a method for evaluating the road network traffic capacity through road network balance degree, and fifthly, setting lengths of different upstream transition regions and different road load coefficients to perform simulation, to obtain the road network balance degree data under lengths of different upstream transition regions of the construction operation area through simulation, and selecting simulation conditions with high balance degrees and good astringency, to obtain lengths of the appropriate upstream transition regions of the construction operation area under different traffic conditions. The method can accurately reflect the influence on the road construction traffic capacity by the lengths of the upstream transition regions of the construction operation area, thereby determining the lengths of the upstream transition regions of the construction operation area.

Description

technical field [0001] The invention belongs to the technical field of road design and relates to a method for determining the length of an upstream transition zone of a construction operation zone. Background technique [0002] Urban road traffic capacity is affected by road conditions, traffic conditions and regulatory conditions. Due to temporary changes in road conditions and traffic conditions due to construction operations, if traffic organization and management are improperly worded, road traffic capacity will be severely reduced, resulting in large-scale congestion of the regional road network. Therefore, it is very necessary to study the impact of construction work areas on road traffic capacity. Existing research techniques, methods and theories include road flow measurement, traffic simulation technology, traffic conflict theory, etc. In the article "Radial Basis Function Neural Network for Work Zone Capacity and Queue Estimation", Karim and Adeli proposed to use...

[0006] (3) Only single-point traffic capacity in the construction work area is considered

The first is to simply deal with the research on driver behavior in construction work areas. The traffic environment in construction work areas is very complex, and the traffic behavior of drivers is also dynamic and unpredictable. Behavior research is the basis for the study of vehicle speed, length, and traffic capacity in work areas; The research on the total amount of simultaneous construction at multiple points in the regional road network is more necessary for the management of actual urban road traffic construction operations. Due to the current situation in my country, the demand for urban road maintenance and repair operations is large, but the traffic congestion in the road network varies. The total amount of construction work and the organization of construction road sections Unreasonable layout will further aggravate urban traffic congestion
