Study On The Key Technologies Of Traffic Organization In Freeway Reconstruction And Project Implementation

The freeways that constructed at early stage in China are already not satisfied the existing traffic demand and the freeway reconstruction is imminent.Traffic organization is the key to insure the implementation of freeway construction.This paper is based on a freeway reconstruction project.This paper studies the key technology of traffic organization.According to the characteristics of the freeway reconstruction,this paper analysis the traffic capacity and set the service level classification table of freeway reconstruction area;This paper analyzes the design principle of traffic organization scheme.This paper mainly focuses on the length of the construction area and the median opening.In order to guarantee the implementation of the transportation organization plan.This paper introduce the blockchain.According to the results,this paper combined with ChangZhang freeway reconstruction project.This paper analyzes the length of the construction area and the Median openings.This paper designs traffic organization construction scheme and establish traffic organization scheme evaluation system.Using the left and right sub-district parallel construction of the way,divided into eight stages to complete the expansion project.This paper determines section construction saturation,average speed,traffic density and average travel delay as evaluation indexes of section traffic organization scheme.According to the service level of construction area scale,this paper make evaluation standards.This paper choose Vissim as simulation software and establish simulation model.Using the dynamic comprehensive evaluation method to evaluate The results show that the first stage to third stage of construction road service level at the maximum of third level and the fourth stage to seventh stage of road service level at the maximum of four.The above conclusions can be obtained that each construction stage in the reconstruction and traffic organization scheme achieves more than four of road service level,and it meet the minimum requirements for the reconstruction.Freeway reconstruction play an important role in the construction of transport infrastructure in the present and future.At present,ChangZhang freeway reconstruction project has been completed,and it has a good effect.In this paper,the research work for traffic organization provides technical support for the reconstruction and expansion.The reconstruction is important to the traffic organization.
