Abstract:With the development of economy and society, the demand for urban road reconstruction and expansion is increasing. The reconstruction and expansion of road should meet the new functional orientation, ensure the new design speed and take into account the status quo of the existing distributed transportation system. In the Shengang Avenue (West Suitanghe Road - Hucheng Ring Road) Reconstruction Project, by analyzing and studying its functional orientation and construction conditions, and combined with the requirements of the Guidelines for Design of High-quality Municipal Traffic Infrastructure in Nanhui New City and the traffic flow forecast results, the overall scheme of the reconstruction project is studied and designed. The obtained results can provide some engineering experience and design reference for the application of the above Guidelines in the practical, and the reconstruction upgrading of urban main roads.
