摘　　要：以昆明地铁1,2号线为例,视地铁站点为网络节点,以自行车优势出行距离为服务半径,构建基于自行车换乘地铁的网络,建立既考虑站点换乘效率和周边用地多样性、又考虑出行者时间预算的可达性测度模型。研究结果表明:由于使用自行车,减小了地铁与常规公交之间的空间转换阻力,使得地铁站点的换乘效率得到显著提高,尤其是在周边公交可达性不高的站点,改善效果明显;自行车换乘地铁对出行者容易形成多目的出行链,使站点周边用地多样性和可停留时间成为影响个体在该站点可达性的关键因素。因此,站点的可达性不是固定值,而会随着个体的出行起讫点和时间预算而变化。Taking Kunming Metro Line 1 and Line 2 as an examp ro station as the network node, taking the bicycle advantage trave radius, the s accessibility sity of the s the bike and ubway transfer network based on the bike model is constructed by considering the effi urrounding land and the time budget of trav bus,the transfer effici cially the markable ency of the metr cessibility of the From the trav e, considering the met distance as the service and ride is constructed, ciency of site transfer, th elers. The results show and the e diver tance between the metro and the o station has been significantly d. Espe surroundings, the metro station is the most re eler＇s perspective,because the bike and ride can be easily formed to make the trip chain, the diversity of the surrounding land and the residence time become the key factor in the impact of the individual, the accessibility of the metro station is no longer a fixed value,but changes with the OD and travel budget of the individual.
