Research On The Optimization Method Of Regional Highway Network Layout From The Perspective Of Holistic Tourism

With the improvement of the living standard of the national economy,tourism has become a normal way of life.In order to meet the market demand,the tourism industry continues to expand the development ideas,innovate the thinking mode and stimulate the endogenous power,and the whole area tourism comes into being.With the arrival of the new era of holistic tourism development,the number of tourists in China has increased dramatically every year,and the requirements of tourism related infrastructure construction have been improved.As the basic support and premise of tourism,transportation is very important to the development of tourism.In order to ensure the development of tourism in the whole region,this paper optimizes the existing unreasonable layout of regional road network to create an efficient and convenient regional road network,so as to meet the tourism traffic demand induced by the tourism development region in the whole region,bring more comfortable and convenient tourism experience for tourists,and promote the innovation,coordination,green,open and sharing of tourism industry Enjoy development.Based on the conventional regional road network layout optimization model and method,this paper fully considers the tourism induced traffic situation in the context of holistic tourism,and studies the regional road network layout optimization method from the perspective of holistic tourism.First of all,it analyzes the impact of holistic tourism on traffic,and studies the travel characteristics of tourists under the background of holistic tourism,so as to analyze the traffic characteristics under the background of holistic tourism.Secondly,combined with the regional social economy,considering the regional traffic demand and the traffic demand induced by Tourism under the background of holistic tourism,it uses the four-stage method to analyze the regional traffic demand under the background of holistic tourism in two parts Ask for prediction.According to the influence of tourism on the scale of highway network in the context of holistic tourism,the tourism income with the highest correlation is selected as the correction factor,and the coefficient K value of highway network is modified.The improved land coefficient method in the context of holistic tourism is obtained to calculate the reasonable scale of regional highway network in the context of holistic tourism.Then,based on the reasonable scale of the road network in the context of holistic tourism,four objective functions and four constraints are selected scientifically to establish a multi-objective optimization model to optimize the level structure of the regional road network.On the basis of the existing road network,the road network based on holistic tourism is established with the goal of the maximum connectivity of the road network,the maximum importance of the road network and the maximum traffic volume induced by tourism The optimization model of network layout is solved by genetic algorithm,and the optimization scheme of regional highway network layout considering the whole area tourism induced situation is obtained.Finally,using Arc GIS software platform and its overlay analysis tools,the optimized layout of regional highway network and ecological environment protection zone are analyzed by overlay map,and according to the overlay map analysis results,the routes affecting the ecological environment are adjusted,and the optimized layout of public road network in the context of holistic tourism is obtained.By considering the impact of ecological environment,we can effectively reduce the harm of highway construction to the natural environment,guarantee the coordinated development of highway construction and holistic tourism,realize the reasonable spatial layout and optimal allocation of facilities,elements and functions,and further promote the implementation of holistic tourism strategy.Through the study of this paper,the method of regional road network layout optimization from the perspective of holistic tourism is obtained,and this method is applied in an example to verify the feasibility of the method,which provides theoretical support and reference for regional road network layout optimization of holistic tourism.
