This paper presents a concept, herein called Combined Alternate-Direction Lane Assignment and Reservation-based Intersection Control (CADLARIC), for organizing directionally unrestricted traffic flows in automated vehicle environment. In the proposed concept, vehicles can use lanes traditionally reserved for the opposite direction of travel. This concept allows left and right turning vehicles to align themselves in an appropriate lane before reaching the downstream intersection, so that they can smoothly go through the intersection without having any conflicts with vehicles from the other movements. Conflicts between through movements are handled by a reservation-based algorithm. To simulate the proposed concept, i.e. allow flexibility of such driving maneuvers that cannot be accomplished in the other existing simulation tools, a new microsimulation platform is developed. The proposed CADLARIC control scheme is evaluated through a comparison with a conventional fixed-time signal control and Fully Reservation-Based Intersection Control (FRIC). The results show that CADLARIC: (i) significantly outperforms other control methods in terms of the traffic performance (i.e. delays and stops); and (ii) generates a reduction of conflicting situations at the network level when compared to FRIC.

组合交替方向车道分配和基于预留的交叉路口控制

本文提出了一个概念，这里称为组合交替方向车道分配和基于预留的交叉路口控制 (CADLARIC)，用于组织自动车辆环境中方向不受限制的交通流。在提议的概念中，车辆可以使用传统上为相反行驶方向保留的车道。这个概念允许左转和右转车辆在到达下游交叉路口之前将自己排列在合适的车道上，这样它们就可以顺利通过交叉路口，而不会与其他运动的车辆产生任何冲突。直通运动之间的冲突由基于保留的算法处理。为了模拟提议的概念，即允许在其他现有模拟工具中无法实现的此类驾驶操作的灵活性，开发了一个新的微观模拟平台。通过与传统的固定时间信号控制和完全基于保留的交叉路口控制 (FRIC) 的比较来评估所提出的 CADLARIC 控制方案。结果表明，CADLARIC：（i）在交通性能（即延迟和停止）方面明显优于其他控制方法；(ii) 与 FRIC 相比，减少了网络级别的冲突情况。
