论文摘要
已显示连接和自动驾驶汽车(CAV)的路由可控性可降低自私路由对网络效率的不利影响。但是,对于系统的利益而言,Cav所有者很容易允许自己在外部控制自己的假设是不现实的。在本文中,我们提出了一种联合路由和定价控制计划,旨在激励骑士通过节省通行费来寻求中央控制的系统 - 最佳(SO)路由,而用户平衡(UE)寻求人类驱动的车辆(HVS)则需要收取很多费用。该问题被公正为双层优化程序,其中高层使用网络基本图(NFD)优化动态通行率,而下层是一种基于混合平衡模拟的动态交通分配模型(SBDTA),考虑到了So-So-so-teekeking Cavs的不同组合。我们将基于反馈的控制器应用于最佳的空间分化的基于距离的拥塞费用,从中寻求所谓的骑士是豁免的;但是,寻求UE的HV受到进入市中心的费用。为了捕获混合自主流量中CAV的独特微观行为,我们还在SBDTA模型中实现了自适应链接基本图(FD)。拟议的联合控制计划鼓励Cav所有者寻求这样的路线,从而减少系统旅行时间。它还劝阻寻求UE的HVS不再充血市中心。我们在澳大利亚墨尔本的小型网络和大规模网络中都展示了拟议计划的性能。
Routing controllability of connected and autonomous vehicles (CAVs) has been shown to reduce the adverse effects of selfish routing on the network efficiency. However, the assumption that CAV owners would readily allow themselves to be controlled externally by a central agency for the good of the system is unrealistic. In this paper, we propose a joint routing and pricing control scheme that aims to incentivize CAVs to seek centrally controlled system-optimal (SO) routing by saving on tolls while user equilibrium (UE) seeking human-driven vehicles (HVs) are subject to a congestion charge. The problem is formulated as a bi-level optimization program where the upper level optimizes the dynamic toll rates using the network fundamental diagram (NFD) and the lower level is a mixed equilibrium simulation-based dynamic traffic assignment model (SBDTA) considering different combinations of SO-seeking CAVs. We apply a feedback-based controller to solve for the optimal spatially differentiated distance-based congestion charge from which SO-seeking CAVs are exempt; but UE-seeking HVs are subject to the charge for entering the city center. To capture the distinct microscopic behavior of CAVs in the mixed autonomy traffic, we also implement an adaptive link fundamental diagram (FD) within the SBDTA model. The proposed joint control scheme encourages CAV owners to seek SO routing resulting in less total system travel time. It also discourages UE-seeking HVs from congesting the city center. We demonstrate the performance of the proposed scheme in both a small network and a large-scale network of Melbourne, Australia.
