Abstract
In recent years, with the continuous development of tourism economy, people travel demand is growing, the existing work is difficult to meet the demand of rapid development of tourism. Show the depth of the work access is not enough, the lack of system of tourism resources in the area of consideration, not form a system of work, poor accessibility of tourism resources. The presence of these problems seriously restrict the rapid development of the regional tourism industry, so the tourism resources, the integration of development and construction of work optimization study is very necessary, this article put forward the consideration of tourism resource accessibility of work layout optimization research also became the tourism and transport need to be considered in the process of development and problems to be solved.
Firstly on the basis of the investigation data of tourist traffic demand are expounded, according to the travel demand analysis of the influencing factors of the tourist traffic demand forecasting and distribution methods and models, put forward the definition of regional work reasonable development scale, through the analysis on the advantages and disadvantages of monly used prediction method of work scale are, on the basis of this puts forward a improved reasonable scale forecasting method, using this bined with other forecasts for bination forecast method of work scale, for the follow-up work to provide the data to predict. In determining the scale of work, on the basis prehensive consideration road traffic demand and supply ability, factors such as the overall work operation efficiency and service level, construct the new grade structure optimization goal, confirm the reasonable grade of the work structure.
Considered in analysis of tourism resources of accessibility of work layout optimization, on the basis of introduction of work optimization bi-level programming models, determine to highway construction cost the most provinces, the sm
