| No more consideration for road service facilities in our existing ordinary trunk road planning and construction in the past.Social service needs of road users along substantially complete by the spontaneous formation of a limited supply. Currently, there are little relevant academic research on common trunk services ordoes thorough research and more information about the common trunk for construction services and facilities. In view of this status quo,this study is more necessary.In this paper, the author analyzes the characteristics of the service facilities and their clients on the basis of the existing ordinary trunk. Discusses the theory and techniques common trunk services settings by the method of combining theory and practice andfocus on the two te two key technical issues which are Regression Model ofService Area Spacing Based on Common National and Provincial Trunk and location model.Firstly,this paper on the basis of a large number of survey data and related information on the location and needs of the function main services are analyzed.Research method to determine the size of the service facilities and classification based on the size of the service facility and features.Secondly,n this paper,determined the general location model trunk road service facilities by drawing highway service area location model. Using Lorentz function to establish a common trunk service area evaluation model which can provide the basis for the score has been built ordinary trunk Rest area set spacing andderived spacing setting the optimal choice.Lastly,research layout and setup service facilities and the research results of the empirical analysis. Seeks to distance regression model and the general location model introduces application services among the main highway. |
