摘　　要：宜昌作为典型的带状多组团城市,地面公交线网发展遭遇单一快速公交廊道容量饱和、普线直达效率较低、廊道外换乘及路权等缺乏保障发展瓶颈,需要进行优化改善。以此为问题导向,通过时间、空间要素的定量评估,以服务优化为目标导向,提出"调模式:调整线网布局及快速公交运营模式""强换乘:构筑廊道换乘与点换乘双类型换乘枢纽""优保障:以路权、同台换乘设计为实施导向,提高整体效率"三大优化策略,对瓶颈进行逐个突破。在不改变甚至缩短总运行时间条件下提高公交服务频次与线路效率,对以快速公交为骨架的大中城市进行公交线网设计与优化具有一定的借鉴意义。As a typical belt-type and multi-group city,the development of ground bus network in Yichang has encountered development bottlenecks such as saturated capacity of single BRT corridor,low efficiency of non-BRT lines,lack of guarantee of transfer or right of way,and so on,which need to be optimized and improved.Based on this,the paper specifically puts forward three strategies through the quantitative evaluation of time and space elements.It includes "mode adjustment:adjustment of network layout and BRT operation mode" "transfer strengthen:construction of corridor transfer and transfer hub" " guarantee stratege optimation:optimize right of way and transfer design".These strategies can improve the public transport service frequency and line efficiency without changing the total operation time,it can also be used for reference in the design and optimization of bus network in large and medium-sized cities with BRT systems.
