The route selection model can ensure the rationality of expressway route planning.In order to meet the rationality requirements of flexible remote sensing route selection of expressways in natural reserves,a flexible remote sensing route selection model of expressways in nature reserves under tree structure simulation was proposed.Through tree structure simulation,the matching degree of remote sensing image distribution function of expressway flexibility was judged,and the inspection statistics of remote sensing image samples of expressway flexibility were constructed by using density cumulative distribution function.According to the inspection steps of tree structure simulation algorithm,the optimal wide window of remote sensing image of expressway flexibility was determined.According to the distribution delay of traffic flow in different sections of expressway in time dimension,the optimal time delay between traffic flow of target section and traffic flow of other sections was predicted,and the traffic flow of expressway was predicted by introducing energy gain.The analytic hierarchy process(AHP)was used to determine the flexible remote sensing route selection scheme of expressway.By establishing the geological exploration function of flexible remote sensing route selection of expressway,the flexible remote sensing route selection model of expressway was constructed to realize the route selection of expressway.The experimental results show that the rationality index of the model proposed is above 0.85,which can meet the rationality requirements of flexible remote sensing route selection of expressways in natural reserves.
