A construction area traffic organization scheme design method considering network load balancing

Abstract

The invention belongs to the technical field of traffic engineering, and relates to a construction area traffic organization scheme design method considering network load balancing. The method comprises the following steps: (1) setting a road network balance hypothesis; (2) constructing a traffic flow redistribution model based on network equalization; (3) solving a traffic flow redistribution model based on network equalization; (4) identifying road network traffic bottlenecks based on a network balance loading result; (5) designing a traffic bottleneck eliminating method based on a network balance loading result; According to the invention, a traditional qualitative analysis method is improved; A'traffic bottleneck 'concept is introduced, a traffic flow redistribution model based on network equalization is established from the overall level of a road network by taking network equalization as a target for special roads and traffic conditions of a construction influence area, reasonable constraint conditions are set, the traffic capacity of a surrounding road network is fully utilized, and the traffic flow is distributed in an equalized manner.

Description

technical field [0001] The invention belongs to the technical field of traffic engineering, and relates to a method for designing a traffic organization scheme in a construction area in the field of traffic engineering, in particular to a method for designing a traffic organization scheme in a construction area considering network loading balance. Background technique [0002] The urban road reconstruction project can improve the traffic environment and relieve traffic pressure, but the service level of the surrounding roads will be reduced during the construction period, which will cause traffic congestion and travel delays in the surrounding area. A reasonable traffic organization method in the construction area can give full play to the function of the road network, use the surrounding paths to relieve the local pressure in the construction area, and at the same time alleviate the negative impact of the construction project on traffic and ensure the normal progress of the ...

Problems solved by technology

[0007] (1) Scholars at home and abroad did not organize and improve according to the principle and goal of balanced road network distribution in the research of traffic organization schemes, but only screened the road sections that need to be diverted or reconstructed from a qualitative perspective, lacking quantitative research

[0008] (2) The traffic organization plan during the construction period of the existing project does not fully consider the various influencing factors in the road network, the organization plan of road sections and intersections cannot be coordinated with each other, and control measures are unilaterally implemented from "line segments" or "nodes"
