The Research On Optimization Of Trafifc Organization In Work Zone Of Expressway Expanding Construction

In recent years,with the development of economy and the traffic volume on highway in our country,many highways built up in recent years appear that the capacity isinsufficient and service level drop.It has become the most important reason for thetraffic jam.For improving these conditions,Expressway Expanding Construction is afeasible way to ease the traffic pressure in highway projects in our country.But now,The reasearch on traffic organization is not enough in China.If the traffic organizationis not reasonable,some possive situation will appear such as traffic jam,transportation delays and resourcewasting.It is not only caused sever economic lossand environmental pollution,but also brought a lot of negative effects to the societyand people.Traffic organization is a very important job in Expressway ExpandingConstruction.It involves the social ecnomic development,the construction organizationand traffic operation management,etc.The effectiveness of the traffic organization hasa direct effect on the construction quality and schedule.It is not only difficultproblem,but also a problem to be resolved instantly.So,It is meaningful to study onoptimization of traffic organization in work zone of Expressway ExpandingConstruction.Based on the literature on the optimization of traffic organization in work zone ofExpressway Expanding Construction,The thesis studies on the traffic flow in thesystem analysis method.After analysis on the capacity of the driver informationprocessing and the factors of the traffic organization,reference on the existing trafficorganization,The thesis has proposed a feasible traffic organization plan.It hasrealized that the traffic organization plan in work zone of Expressway ExpandingConstruction becomes reasonble,feasible and ecnomic.
