摘　　要：带形城市发展期带状特征凸显,通过大量的参数类比得出,由单核向多核发展这一特殊发展期的交通特征:老核心区原有用地模式调整难,高峰时易发生交通拥堵;城市带向发展拉大了出行距离,居民的出行次数、出行距离和平均出行时间均会显著增加;新核心区发展初期,交通需求仍主要集中在老核心发展成熟区内;伴随新核心区发展,核心区之间的出行需求量快速增大,新老核心间轴向干道会集中大量交通,高峰时交通压力过大;新区发展逐步成熟后,新老核心区间联系会更密切,新核心内部出行增大。Band city development strip highlighted characteristics, through a large number of parameters of analogy, from single to multiple nuclear development traffic characteristics of this special period： old core original land adjustment difficult, easy happening peak traffic congestion; Urban belt to the development of widening the trip distance, the residents travel frequency, travel distance and the average travel time will increase significantly; New core development initial period, the traffic demand is still mainly concentrated in the old mature core development zone; Along with the new core development, demand of travel between the core increases rapidly, between the new and old core axial artery will focus a lot of traffic, rush hour traffic pressure ; New area development gradually mature, new and old core interval ties more closely, the new core internal travel increases.
