| With the continuous development of 3D visualization technology and the vigorous promotion of the country,the current application of visualization technology in the construction field has achieved great success and formed a complete application model.It is still in its infancy,and there is still a long way to go before the actual engineering application.This article first reviews the research data at home and abroad,summarizes the current application fields and results of visualization technology,and analyzes the existing problems in the design of urban roads,in order to draw the necessity of visualization technology applied to the optimization of urban road design.Then,the road visualization technology and the road BIM technology are explained,and the similarities,differences and inclusion relationship between the two are explained through a comparative analysis.The mainstream application platforms for road visualization at home and abroad are studied.The advantages and disadvantages of each application platform are analyzed.Road visual modeling platform.At present,the domestic urban road design is developing from the traditional two-dimensional design to the three-dimensional visual design.This paper has conducted in-depth research and exploration on the methods of visualization technology applied to the optimization of urban road design.In view of the problems existing in the traditional two-dimensional road design,this paper proposes A set of design optimization schemes based on visualization technology,including the establishment and processing of three-dimensional digital terrain,optimization of route design,optimization of profile design,optimization of cross-section design,optimization of intersection design.The construction method and process of road visualization model are described.Applied to the optimization of urban road design,and explored a standardized implementation technical route.At the same time,in combination with an example of a arterial road project in Xinjiang,the visualization technology was used to design and optimize the engineering example project.The road visualization model for this project was successfully constructed,and the proposed urban road design optimization scheme based on visualization was verified with examples to prove the technology.The feasibility of the framework and implementation plan provides reference value for the subsequent application and promotion of road visualization technology.On this basis,the three-dimensional road visualization model constructed by the engineering example is used to assist the optimization of the design scheme.The visual model of the design scheme is subjected to model rendering,construction simulation,driving simulation,and traffic simulation simulation.The project decision maker finds the problems in the design plan in advance and feedbacks in time,and realizes the dynamic optimization of the design plan by adjusting the design parameters,and finally obtains the optimal design plan. |
