Research On Evaluation Of Expressway Planning In Waterfront City Based On Fuzzy AHP

At present,our country is in a stage of rapid urbanization.To achieve the sustainable development of cities,urban transportation in our country enter the development stage of three-dimensional.Expressway is an important part of urban three-dimensional transportation,expressway planning is an important content of transportation planning.But there are still many problems in the planning and design of the expressway.Expressway is large-scale infrastructure,planning expressway advanced,research the evaluation issue of expressway are important,especially the waterfront city.This dissertation with the goal of the construction of diversified,hierarchical,rapid,three-dimensional,networked urban comprehensive transportation system and waterfront urban expressway network,guided by the Mixed-Scanning method of planning,analysed the relate factors of expressway planning and evaluation in waterfront city,study the relate theory and key problems in planning and design of expressway.Then established the evaluation model of expressway planning in waterfront city based on fuzzy analytic hierarchy process,and verified its usability through the instance of evaluation of expressway planning in Wuhan.The main research contents of this paper are as follows:1)Based on the study of conception,types,size,space morphology and land use characteristics of waterfront city,motorized transport characteristics is analysed,then the influencing factors of the planning decision,implement,evaluation of expressway in waterfront city are analysed,includes urban comprehensive transportation system,nature geography factors,urban planning and design,and so on.2)Based on the urban planning method of Mixed-Scanning,analysed the internal indicators for evaluation of expressway planning in waterfront city.From the level of macroscopic decision-making and the angle of urban design,researched planning decision problems such as the development strategy of rapid transportation,placement scheme of networks,routes and nodes,built the system hierarchical planning theory.From the level of project decision-making and angle of plan implementation,researched planning implement problems such as the structure and aesthetic design of expressway,built the theory of three-dimensional concept design of expressway.And take the planning theory that built previously as the basis of the evaluation index system of expressway planning in waterfront city.3)Combined the evaluation aim of expressway planning in waterfront city,planning contents of expressway and influencing factors,meet the characteristics of waterfront city such as high requirement of landscape and environmental protection,the planning main points such as high degree of three-dimensional of expressway in waterfont city,constructed the comprehensive evaluation index system,established evaluation criterion and determined the weight of each index,calculated the comprehensive evaluation results and evaluated the project,built evaluation model of expressway planning in waterfront city based on Mixed-Scanning and fuzzy AHP,strived to evaluate the waterfront urban expressway system accurately.4)Taken the planning and construction of waterfront and non-waterfront urban expressway system both at home and abroad as reference,analysed the expressway system of Wuhan.Evaluated the expressway planning scheme of Wuhan comprehensively by fuzzy AHP method based on Mixed-Scanning and MATLAB scientific calculate software,proposed optimization suggestions of expressway in Wuhan and expressway system pattern suitable for waterfront city.The MS fuzzy AHP model for evaluation of expressway system planning in waterfront city is proposed in this paper,it integrates the planning and design factors by different levels of scanning,the purpose is clear,the results are intuitive,it is simple and strong practicability.The SWOT-AHP model for expressway system strategic planning in waterfront city is also established.The research of this paper has a certain value for the long-term planning of waterfront urban expressway network and the protection of waterfront characteristics and environment.
