In order to promote the development of the green highway industry and effectively guide the construction of green service areas,this paper combines BIM technology and the cloud matter-element model to establish a pre-evaluation model of green service areas.Through literature analysis,expert consultation and field investigation,the pre-evaluation index system of green service area is constructed.SPSS software is used to improve the analytic hierarchy process through factor analysis to determine indicator weights.Based on the characteristics of BIM technology,such as collaborative simulation and data information,the original analysis data is extracted.The cloud model is used to improve the matter-element theory,and the evaluation cloud chart is established by Matlab programming,and the evaluation grade is determined through the calculation of membership degree.It is applied to the project pre-evaluation of Taipingchuan service area,and the“2-star”evaluation results are obtained,and the optimization suggestions of design scheme are put forward.The results show that the evaluation model can use the simulation and optimization characteristics of BIM and the fuzzy quantitative characteristics of cloud matter-element model to effectively guide the cyclic optimization scheme of green service area in the design stage,and lay the foundation for green construction and green operation,which has practical significance.
