The Research On Traffic Organization Of Highway Interchange Reconstruction

As the important social infrastructure in our country, high-grade highway has prominent advantages in transport capacity, traffic speed and safety performance. And now interchange has become a indispensable important part of high-grade highway and city road with heavy transport, with the development of social economy, the improvement of the regional road network and traffic growth, interchange as a high-grade highway traffic transfer hub, the carry of traffic flow is increasing, also transportation of significant changes have taken place, so in studies the traffic organization related technical reconstruction and construction areas become inevitable trend.This paper first summarizes the research situation of domestic and foreign scholars about each working in the reconstruction traffic organization theory and the the security measures, determine the main content is for highway reconstruction and study the interchange traffic organization. Then, on the highway interchange reconstruction of traffic organization influence factors are analyzed in detail. Analysis shows that working in the exchange and normal traffic transportation characteristics of road is different often makes each section traffic flow redistribution and produce traffic bottlenecks. Then, based on network of traffic organization, coordination and complexity, further study the construction scheme design and traffic organizational optimization design of the single interchanges reconstruction for the trumpet interchange. Finally, combined the LiLing east interchange reconstruction project, design traffic organization and traffic organizatioal optimization.For the research of interchange reconstruction traffic organization, will largely improve the interchange system’s traffic capacity and service level during the construction, at the same time accumulated valuable experience and lessons for future interchange reconstruction.
