AI 中文摘要
智能交通系统(ITS)的发展很大程度上得益于无线通信技术的进步。动态路径规划作为ITS的关键组成部分,传统上聚焦于路径容量、行驶时间等指标。本文提出一种新颖的双因素方法,将行驶时间估计与无线资源可用性相结合,形成面向网联车辆(CVs)的创新路径规划方案。为解决这一双目标路径规划挑战,采用深度强化学习(DRL),所提出的方法命名为保障信息年龄的动态路径规划(AGDRP),可有效平衡行驶时间与信息年龄(AoI),通过随时间的自适应学习提升路径规划性能。仿真结果表明,AGDRP优于仅聚焦行驶时间优化的基准方案,证实纳入AoI最小化可显著提升路径规划性能,超越传统基于行驶时间的方法。
英文摘要
The advancement of Intelligent Transportation Sys- tems (ITS) has been significantly driven by progress in radio communication technology. Dynamic route planning, a key com- ponent of ITS, traditionally focuses on metrics such as route capacity and travel time. This paper presents a novel dual- factor approach that integrates travel time estimation and radio resource availability into an innovative route-planning scheme for connected vehicles (CVs). To address this dual-objective route planning challenge, we employ Deep Reinforcement Learning (DRL). Our approach, called AoI-Guaranteed Dynamic Route Planning (AGDRP), effectively balances travel time and Age of Information (AoI), enhancing route planning performance through adaptive learning over time. Simulation results demon- strate that AGDRP outperforms the baseline scheme, which solely focuses on travel time optimization. In fact, we show that incor- porating AoI minimization significantly enhances route planning performance beyond conventional travel-time-based approaches.
