Study On System Selection In Monorail Transit Demonstration Line Of Yongan South To Huanglongxi In Shuangliu District

Chengdu is currently in the critical period of the rapid development of rail transit network construction.The current rail transit in shuangliu district is relatively short,and the internal public transport system needs to be improved.The construction of monorail transit can connect the black area of the rail transit in shuangliu district with the urban rail transit network of Chengdu city,and provide the residents with perfect travel service.Not only the problems such as lack of public transport,low levels of traffic facilities should be solved,but huanglongxi comprehensive upgrade of the scenic spot should be drived through the construction of monorail transit demonstration line of Yongan south to Huanglongxi.The development of huanglongxi local tourism project can be effectively promoted through chosen appropriate monorail transit system.And a good opportunity will be provided to the shuangliu district industry.The rail transit network density in shuangliu district also will be increased.Based on the study of the existing monorail transit system and the economic and traffic circumstance of shuangliu district,the fuzzy analytic hierarchy process is used in this paper to make a decision on the choice of monorail transit system in the shuangliu district.The following several aspects of work is mainly carried out in this paper..(1)Three kinds of monorail transit system : rubber wheel guide tram,straddle-type monorail,suspended monorail are selected through information collection.The comparison between monorail transit system and other urban rail transit system is summarized.The basic concept,main characteristics and main application of these three kinds of monorail transit are expounded,paying the way for the choice of monorail transit system.(2)Through the analysis of urban rail transit system selection at home and abroad,type selection is made clear when the factors and the main indicator of decision-making method.Combined with the summary of the characteristics and applications of the monorail transit system,the analytic hierarchy process is adopted to give the weight of the elements of affecting the monorail transit system choice and fuzzy comprehensive evaluation is used for monorail transit system of decision making.(3)Summarized the whole situation of the shuangliu district,referring to the situation of its urban development,traffic planning and monorail transit demonstration line,the technology reliability,economic rationality,service requirements and the impact on the city 4 criterion layer 12 set-up evaluation decision system is selected as the index factors.The analytic hierarchy process is used to the index weights factors given and the expert scoring method is adopted to scores of each index.The fuzzy comprehensive evaluation is used to calculate the monorail transit system satisfaction.The monorail transit system is adopted in decision making.
