摘要：为有效满足BRT或轻轨系统的运行需求，提出在带有固定左转车道的繁忙通勤走廊中央设置一条BRT或轻轨专用车道用于双向运营的概念。由此产生了车辆相交问题，其相交空间设置于由左转车道产生的未利用或未被充分利用的道路中央隔离带。提供了公交车站和相交空间的概念设计可选方案和几何布局示意图，并考虑运行速度、发车间隔、相邻相交空间的距离及相交空间数量等条件，分析系统性能。为确保具有实用性，研究了系统在现有交通走廊上的可实施性。由于该系统具有利于TOD发展的潜力，也可作为未来发展两条专用车道系统的中间步骤。

Abstract：This paper proposes the concept of a bus rapid transit (BRT) or light rail system that effectively requires only one dedicated but reversible lane to support two-way traffic in the median of a busy commute corridor with regular provision of left-turn lanes. Traffic crossing is accommodated on the otherwise unused or underused median space resulting from provision of left-turn lanes. Conceptual design options and geometric configuration sketches for bus stops and crossing spaces are provided. System performance in terms of travel speed, headway operations, distance between two neighboring crossing spaces, and number of crossing spaces is also analyzed. To ensure practicality, we study implementation of such a system on an existing corridor. Such a system is also useful as an intermediate step toward a two-dedicated-lane system because of its potential for facilitating transit-oriented development.
