Study On The Traffic Organization And Safety Measures For Reconstruction Of Expressway Interchange

At present, our country freeway interchange gradually enter the large-scaleexpansion period, along with the implementation of interchange reconstruction,caused a lot of problems for interchange reconstruction area of safe operation andconstruction of traffic organization, such as road congestion, frequent road accidents.Therefore, to carry out the expressway interchange reconstruction traffic organizationand security study is very urgent.This article unifies the domestic and foreign research present situation, proposedinterchange reconstruction traffic organization and security framework, and graduallyto conduct the analysis research, in order to achieve the purpose of safe and smoothfor interchange reconstruction area. According to the actual interchangereconstruction examples, and combining the theory for analyzing the interchangereconstruction scheme, meanwhile discusses the direct cause for leading tointerchange reconstruction. Based on the discussion of interchange reconstructionscheme, making a detailed analysis and research of organization principle、trafficorganization type、selection of organization type for interchange reconstruction period.In view of traffic organization characteristics for interchange reconstruction, furtherdiscuss the influence factors of traffic safety, traffic facilities, traffic safetymanagement and emergency plan in detail during the period, for traffic security ofinterchange reconstruction provided a basis.Through comparative analysis, to determine the traffic safety、constructionperiod、investment economic and social effects of four indexes and comprehensiveanalysis of advantages and disadvantages as interchange reconstruction of trafficorganization scheme of evaluation criteria, with a purpose to interchangereconstruction traffic organization plan provide a basis.
