Research On The Reapplication Of Lost Space In The Lower Part Of Urban Three-dimensional Transportation

As a necessary three-dimensional transportation facility in the city,the viaduct is short of the theory of design and utilization of the lost space in the lower part of the urban three-dimensional traffic at home and abroad,and has not been applied to practice in the aspect of theoretical guidance.Therefore,I think that the application of the lost space in the lower part of the three-dimensional traffic is very valuable,which provides a theoretical basis for the utilization of the lost space in the lower part of the viaduct and explores reasonable and effective practical methods.Based on the analysis of the present situation of three-dimensional traffic in Changchun,taking the western expressway of Changchun as an example,this paper analyzes the source of the problem in view of the adverse effects on the city and residents in the space under the bridge.When increasing the utilization rate of space,we should fully consider the needs of people,at the same time,integrate the regional and cultural characteristics of the city into the landscape design of the lost space in the lower part of the three-dimensional traffic,and bring new vitality and color to the lost space.
