摘要

自动驾驶汽车（AV）可以解决传统单向车辆共享系统面临的车辆迁移问题。本文探讨了混合共享车辆（SAV）和人-车（SHV）系统的确定性时变系统优化，为混合车辆流的情况提供了基准。在这样的系统中，系统规划器确定交通网络中的车辆-旅行者分配和最佳车辆路线，以满足不同旅行者的预定旅行需求。由于涉及大量车辆，出行时间被认为是拥堵的内生因素。利用链路传输模型（LTM）作为交通流模型，将确定性时变系统最优解公式化为线性规划模型，以最小化综合成本，包括出行时间成本、等待时间成本和空车重新定位时间成本。通过算例验证了系统的性能和模型的有效性。

Dynamic system optimal performances of shared autonomous and human vehicle system for heterogeneous travellers

ABSTRACT Autonomous vehicles (AV) can solve vehicle relocation problems faced by traditional one-way vehicle-sharing systems. This paper explores the deterministic time-dependent system optimum of mixed shared AVs (SAV) and human vehicles (SHV) system to provide the benchmark for the situation of mixed vehicle flows. In such a system, the system planner determines vehicle-traveller assignment and optimal vehicle routing in transportation networks to serve predetermined travel demand of heterogeneous travellers. Due to large number of vehicles involved, travel time is considered endogenous with congestion. Using link transmission model (LTM) as a traffic flow model, the deterministic time-dependent system optimum is formulated as linear programming (LP) model to minimize the comprehensive cost including travellers’ travel time cost, waiting time cost and empty vehicle repositioning time cost. Numerical examples are conducted to show system performances and model effectiveness.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
