信号交叉口动态配道是解决交通需求变化问题的一种可能的对策。然而，运营效率受到驾驶员不熟悉的影响。本文利用中国五个交叉口的实测数据，对动态配道交叉口的运行效率进行了评价。共捕获车辆63488辆，按行驶车道分为4组：第1组，可变引道;第2组，可变车道相邻车道，车道使用相同;第3组，可变车道相邻车道，车道使用不同;第四组为交叉口其他引道处与可变车道车道具有相同车道用途的车道。统计学分析四组间饱和流速的差异。建立了饱和流量调节模型。结果表明，动态车道分配使可变车道和相邻车道在不同车道使用情况下的饱和流量分别降低了22.86%和9.80%。对于可变车道，饱和流率的降低主要来自三个方面：交通分配不均（8.9%）、强制换道（10.7%）和车道阻塞（4.9%）。
The dynamic lane assignment at signalized intersections is a possible countermeasure to address the traffic demand variability problem. However, the operational efficiency is affected by the unfamiliarity of the drivers. This paper evaluates the operational efficiency of the intersections with dynamic lane assignment using field data collected at five intersections in China. A total of 63488 vehicles were captured, which were divided into four groups according to the lanes they drive on: Group 1, the variable approach lane; group 2, the lane adjacent to the variable lane with the same lane-use; group 3, the lane adjacent to the variable lane with different lane-use of the variable lane; and group 4, the lanes with the same lane-use as the variable lane at other approaches of the intersection. The statistical analysis was conducted to identify the difference of saturation flow rate among the four groups. A saturation flow rate adjustment model was established accordingly. Results indicate that the using of the dynamic lane assignment decreases the saturation flow rate of the variable lane and the adjacent lane with different lane-use 22.86% and 9.80%, respectively. For the variable lane, the reduction of the saturation flow rate comes from three aspects: the unequal distribution of traffic (8.9%), the mandatory lane-changing (10.7%), and the lane blockage (4.9%).
