Research On The Optimization Scheme Of Xiamen Public Transit Networks Based On Subway

With economic growth,urban expansion and population growth,the urbanization rate of Xiamen is nearly 90 percent.Surging demand for motor vehicles and transport,urban congestion and restricted urban development.Xiamen City Planning proposes to accelerate the Bay City and Building "Bay Area-oriented tour through" traffic pattern.In 2013,Xiamen began construction of Metro Line 1,which runs from south to north through the largest traffic corridor in the area of Siming,Huli,Jimei three districts,which is 30.3 kilometers long.How to build an integrated network of metro and conventional bus,so as to integrate,connect and operate well,become an important practical subject that should be studied carefully in this paper,under the background of rail transit into to Xiamen,taking metro line 1 as an example,the traditional "four stages" method is adopted to forecast the traffic demand,the key is focused on the practice of urban transit network optimization applications.This paper firstly introduces the mode of the public traffic guide city development,integration and development of the rail transit and bus transit,traffic planning and other related theoretical research,absorb domestic and foreign cities in the successful experience of transit network layout,proposed combining with underground corridor,on the basis of the subway line to build multi-level integrated transit hub site,planning scientifically,adding practical cohesive guidance system,and other important concept promote the development of the subway and conventional bus fusion,both competition and cooperation between the two.Secondly,analysis of the traffic situation of Xiamen,current situation of conventional bus and rail transport operations,grasp the travel structure of residents,and carries on the SWOT analysis of xiamen public transportation development,put forward in the rail transportation,conventional public facing challenges and problems,the rail line 1 of planning operations will make the conventional public facing reform,through the application of "four stages" planning model,based on the analysis of population,economy and transportation development policy and related influence factors,on the basis of predicting the future years of traffic trip distribution,traffic distribution allocation through cooperation competition model,and the passenger traffic forecast.In the end,the prediction results are combined with the actual situation,and the optimization of the bus network is put forward.This paper discuss the specific impact analysis on the public transportation network ofMetro Line 1,involving 112,about one-third of the bus lines,about 1.06 million people,more than four percent of passenger traffic;The combination of various modes of transportation becomes the optimization goal of the whole,and proposes the optimization of group mode and other optimization ideas to better serve the citizen passengers..Combination of subway construction theory-oriented optimization index,applied theory principle,make full analysis of the specific situation of Xiamen city and metro line 1,theory-oriented and optimization of the four specific measures are put forward,including 13 bus terminal,layout article 27 bus lines and various kinds of regional,community park bus,etc.In this paper,five main methods for the integration of subway and ground bus are analyzed,and three Suggestions are put forward.At last,the main conclusions and optimization Suggestions are summarized,and three points are proposed for further research.
