公交专用道的设置是公交优先、提高城市交通系统效率的一种策略。然而，在传统的专用公交专用道(TBL)设计中，只有直通公交可以优先使用。提出了一种动态公交专用道(DBL)设计，在信号周期的不同时段，出口的公交专用道可以动态地用于左转公交车和对向直通公交车。在路口上游设置中央开口处和前置信号灯，以控制左转公交车进入对面专用道的许可。将车道标线、信号配时和中线开口处的位置综合在一起，建立了一个混合整数非线性规划模型。以交叉口的平均人员延误为目标，平衡公交车和私家车的性能。实例研究和广泛的数值分析结果表明，DBL设计在减少平均人员延误方面具有良好的性能。与TBL设计相比，当一条线路的运量大于900车速/小时，左转比例大于0.1，公交比例大于0.05时，平均人员延误可减少10%以上。此外，采用DBL设计可以降低公交专用道的分配门槛。
The allocation of exclusive bus lanes is a strategy for giving priority to buses and improving the efficiency of the urban transportation system. However, in the traditional exclusive bus lane (TBL) design, only the through bus can be prioritized. This paper presents a dynamic exclusive bus lane (DBL) design, in which the exclusive bus lane at the exit can be dynamically used for the left turn buses and the opposing through buses during the various periods of a signal cycle. A median opening along with a pre-signal are set upstream of the intersection to control the permission of the left turn buses entering the opposing exclusive bus lane. An optimization model is formulated as a mixed-integer nonlinear program, into which the lane markings, signal timings, and location of the median opening are integrated. The average person delay of the intersection is used as the objective for balancing the performance of buses and private vehicles. The results from the case study and extensive numerical analyses reveal the promising properties of the DBL design for reducing the average person delay. As compared with the TBL design, a reduction in the average person delay of more than 10% can be achieved when the volume in a leg is greater than 900 veh/h, the left turn proportion is greater than 0.1, and the bus proportion is greater than 0.05. Moreover, using the DBL design can reduce the threshold of the allocation of the exclusive bus lane.
