最近的研究已经证明了互联自动驾驶汽车（CAV）对城市网络性能的潜在好处。具体而言，已经提出了一些政策和相关技术的建议，这些政策和技术在CAV的比例相对较高时表现得更有效，或者完全排除人类驾驶的车辆（HDV）。同样的研究机构也确定了这些网络面临的几个挑战，特别是在共享自动驾驶汽车（SAV）的背景下。我们提出了一个车道使用政策的网络中的专门CAV的目标是保持任何两个类，任意优先级分配制度的优先级。我们调查这样一个政策的优点，通过采用一个简单的占用为基础的，两个类的优先级计划在网络的SAVs。我们将证明，通过授予和保留占用车辆的优先权，乘客的平均旅行时间和速度得到改善，而其他车辆（即未占用车辆）的这些措施的退化有限。拟议的车道使用政策是根据街道网络的实际物理限制制定的，不需要轨迹预留。
Recent research has demonstrated the potential benefits of connected, autonomous vehicles (CAVs) to the performance of urban networks. Specifically, several proposals have been made for policies and related technologies that either perform more efficiently when the proportion of CAVs is relatively high or that exclude human driven vehicles (HDVs) altogether. This same body of research has also identified several challenges faced by such networks, especially in the context of shared autonomous vehicles (SAVs). We propose a lane-use policy for networks of exclusively CAVs with the goal of preserving priority within any two-class, arbitrary priority assignment regime. We investigate the merits of such a policy by adopting a simple occupancy-based, two-class priority scheme in a network of SAVs. We will demonstrate that by granting and preserving priority for occupied vehicles, average travel times and speeds for passengers are improved with limited degradation in these measures for other, i.e. unoccupied, vehicles. The proposed lane-use policy is developed on realistic physical limitations of the street network and without the need for trajectory reservations.
