【Abstract】: Use of GIS, spatial analysis technology of computer components and rail transportation and conventional theory-oriented and scientific methods of analysis and evaluation model, the integration of regional population, land use status and talk to public transport, rail line network data, theory-oriented and operating data, site and bus IC card data GPS data, such as huge amounts of information, the construction of ningbo city rail transit and conventional public transport interchange digital management system. The system can analyze and evaluate bus passenger flow and bus routes, and realize real-time dynamic management and emergency response of bus vehicles. Experiments show: the system can detect the bus passenger volume effectively, rail transit passenger volume, effective evaluation situation and warning passengers crowded degree, such as the front site operation of early warning, crowded roads and public transportation passenger load such as early warning for ningbo joint integration of rail transit and conventional public traffic development provide powerful auxiliary decision-making.
【Key words】: Component GIS technology; Connection digitization; Rail transit; Regular bus; The information system

根據(jù)最新的《寧波市城市軌道交通線網(wǎng)規(guī)劃(修編)》目前形成草案[1]。依照2020年的寧波城市軌道交通建設(shè)方案,寧波市軌道交通線網(wǎng)規(guī)劃由7條線路組成[2],總長約164 km,設(shè)站113座軌道交通進(jìn)出口站點,其中包括11座線路換乘站[3]。目前,常規(guī)公交和城市軌道交通是寧波市交通運營組織的兩大重要組成部分[4]。其中,軌道交通的布局建設(shè)具有固定性,因此,常規(guī)公交線網(wǎng)是城市交通資源靈活布局方案設(shè)計的核心內(nèi)容[5]。
國外的研究軌道交通與常規(guī)公交接駁數(shù)字化管理系統(tǒng)主要側(cè)重在常規(guī)公交、軌道交通線路規(guī)劃、設(shè)計的應(yīng)用,美國波特蘭市是較早采用GIS技術(shù)進(jìn)行軌道交通線網(wǎng)規(guī)劃管理的城市。……
