Study On Traffic Dynamic Control,emergency Scheduling And Remote Control Technology Of Construction In Highway Reconstruction

Traffic organization scheme is one of the key problems in the expressway reconstruction and expansion project.The various traffic organization scheme not only affect the construction period and construction difficulty of the expressway renovation and expansion project,but also reduce the traffic capacity and service level of the surrounding road network in different degrees,and the construction and the road network service level are mutually impact.This paper focuses on the traffic organization scheme of Beijing-Shijiazhuang Expressway reconstruction and expansion project.Beijing to Shijiazhuang Expressway geographical location is special,the surrounding road network diversion capacity is good.By collecting the basic data of the surrounding road network,establishing the micro simulation platform of the surrounding road network,based on the measured traffic flow data of the simulation parameter calibration and verification,simulation checkpoints truck traffic parameter,analysis of the impact on the surrounding.Output results using simulation platform,Provide decision basis for the selection of the scheme.The specific research contents are as follows:First,determine the surrounding conditions of the Beijing-Shijiazhuang Expressway,by collecting,summarizing and sorting the basic data of the surrounding road network,traffic management and control data and other information,combined with the Beijing-Shijiazhuang Expressway actual traffic data,get the key sections and key points,the bottleneck of the sub-vehicle traffic;Secondly,using the OD traffic volume reversal technique,according to the peak traffic volume to reverse the consider area OD matrix,use this OD matrix as the data entry for the TransModeler platform;Thirdly,consider the peak traffic conditions,through the basic data,combined with the simulation principle,using TransModeler software to build the surrounding road network simulation mathematical model,use the latest consider results to set the relevant parameters in the model;Finally,using the simulation model which has been established,simulate the Microcosmic Model of Traffic Organization Scheme to get the output result.On this basis,through the investigation of the questionnaire to further confirm the Traffic organization scheme,then evaluate and compare different schemes.
