| In response to the rapid development of urbanization and motorization, theworsening traffic environment, each big city is to emphasize the important role ofpublic transportation in the development of "livable and appropriate business city",especially in construction the green ecological、 sustainable city, track traffic systemplanning and construction is regarded as a very as the important work. In recent years,the Beijing city government at all levels attach more and more importance to the cityrail transit planning and construction work, to alleviate traffic pressure on the citytrack traffic in Beijing have very high expectations.Common conventional bus and rail transit transport most of the passengertraffic,there is competition between the two is inevitable, but also inter dependent.Due to the construction of rail transit in China is in its infancy, there is no formationof the network, in order to improve the rail transport of radiation to attract a rangeadvantage only through conventional public, and the full realization of the rail traffichigh volume, low cost occupies and energy consumption as well as the advantages ofthe relatively small environmental pollution.The combination of the two complementeach other, enhance the attractiveness of public transport to ease traffic pressure of thebig city, established for the dominance of urban traffic, and increase the proportion ofpublic transport in the passenger market, public transportation will play an importantrole. With the opening of the light rail Yizhuang the Beijing Economic andTechnological Development Area(Referred to as "BDA") traffic travel behavioroccurs larger conventional way to travel, motor vehicle, bicycle, bus, conventionalbuses, taxis gradually converted to the main rail transit travel, other transportationway secondary. Yizhuang light rail opens before and after the resident travel behaviorresearch is to implement bus priority development strategy of theinevitablerequirement, and also the important support of scientific planning and management of city public traffic system. Through the analysis of the traffic travel behavior beforeand after the opening of the light rail Yizhuang traffic impact study, we can clearlydraw the opening of the rail transportation, regional travel behavior and traffic impact,an important role in the future of rail transportation planning and operations.This paper based on the2008,2011(Yizhuang rail line opened before and afterthe two characteristics of years) Yizhuang district resident trip survey of raw data, theestablishment of Yizhuang residents travel survey based on traffic database, realizethe traffic survey data, finishing, storage,query and other functions in Yizhuang,according to the survey of Yizhuang residents travel content, to realize theconsolidation and analysis based on travel survey data. At the same time, the travelbehavior index of the two trip survey were sorted and analyzed, including the residenttravel mode,travel rate, travel purpose, travel time, travel the temporal and spatialdistribution, bus travel and rail travel choice. Through comparison and analysis, basedon the analysis of quantitative indicators, analysis of the basic traffic behavior beforeand after the Yizhuang development areatrack traffic opening is obtained, and thecorresponding analysis results.According to the prediction of Beijing Subway Yizhuang Line passenger flowanalysis at different periods and comparative analysis of the actual passenger flowand passenger flow forecast, the following research work has been deployed.1. Thepresent situation of passenger flow in Beijing Subway Yizhuang Line basicallyreached the scale of the initial forecast station.2. The early opening of Yizhuang Line,time characteristics and prediction of passenger flow of the basic agreement.3. Thestation passenger flow comparative analysis results showed that most of the site errorrate is very big.4. Development of Land along YIZHUANG Line had a large gapbetween expected and actual.5. And now the maximum cross-sectional flowexceeded the actual maximum capacity during peak hours.Through the study of changes before and after the opening of the MTR, wecreated traffic analysis evaluation model of Yizhuang. Inside track to YIZHUANGLine and BDA living and working population range as the main research object,Yizhuang Line before and after the track opened at different time node structurecomposed of transportation study area, residents and travel characteristics of the employed population changes and developments YIZHUANG Line to achieve beforethe opening of the impact analysis and the assessment and provide a reference forfuture planning, construction and operation of rail traffic.According to the study of trip characteristics in Yizhuang Line at Various timeperiods as well as the opening of the front and rear and combined with the planning,the following research work has been deployed.1. With the Yizhuang Line opened,there is great influence travel behavior and commuting residents nearby. From the tripto scale, the opening improved bus travel rail travel rates. From the point of traveltime, the opening of Yizhuang Line significantly reduced the travel time andimproved the efficiency of travel. From the view of public traffic flow, after theopening of Yizhuang Line transit flow increased. With the opening of Yizhuang Linethe traffic growth has been slowed down, and the speed congestion level of the mainchannel have been appeased.2. Analyzed of the guiding role of resident’s travel andpassenger traffic evaluation to planning and construction. According to the forecastand the actual operation state of part of the deviation phenomenon, analyzed thereasons. Put forward suggestions for improvement passenger flow forecast. For landuse, planning and construction of urban rail transit and urban transportationimprovements proposed layout views. For operational management and track accessscheme proposed effective suggestions. Also present the recent constructionsuggestions to Yizhuang Line surrounding traffic hub.Through research and analysis, although some research to get results, but stillneed to do further research on the follow-up problem.1. In the future with the travelsurvey data of continuous improvement, should be added in addition to railtransportation factors, other factors associated with major consideration should begiven.2. Urban Rail Traffic Forecast need based on the rich and accurate data, andbased on scientific prediction tools. Later on the Rail Transit Passenger Forecastingoptimizes. With the data processing, the study found that radiation-track line on theurban fringe area of small towns and industrial agglomerations within the scope of thecity is much bigger. In the future, in order to ensure the passenger flow forecastaccuracy, passenger flow forecast in this type of rail lines should focus on consideringthe size of its services according to the actual situation. It provides effective help to the rail station, infrastructure development and post-operational management. |
