Traffic congestion on motorways is a serious threat for the economic and social life of modern society as well as for the environment, which calls for drastic and radical solutions. Conventional traffic management measures, currently applied, are valuable, but face limitations. During the last decades, a variety of vehicle automation and communication systems (VACS) have been developed and deployed, and many more are expected to appear in the near future. These systems provide a novel basis for a new generation of traffic management, which exploits emerging vehicle automation functions and connectivity channels to enable sensible traffic flow improvements in terms of efficiency and safety. A number of innovative concepts, tools and results that open up new horizons for traffic management research and practice in presence of VACS have been produced recently in the frame of TRAMAN21, an ERC Advanced Grant. This paper presents a collection of novel problems as well as of related traffic flow modelling, estimation and control developments for motorway traffic that can be used in the evolving traffic environment with VACS.

高速公路上的交通拥堵严重威胁着现代社会的经济和社会生活以及环境，这要求采取彻底的彻底解决方案。当前应用的常规交通管理措施是有价值的，但存在局限性。在过去的几十年中，已经开发并部署了各种车辆自动化和通信系统（VACS），并且有望在不久的将来出现更多的自动化和通信系统。这些系统为新一代交通管理提供了新颖的基础，该管理利用了新兴的车辆自动化功能和连接通道，从而在效率和安全性方面实现了合理的交通流量改善。许多创新概念 最近在ERMAN高级补助金TRAMAN21的框架中产生了工具和结果，这些工具和结果为VACS的出现为交通管理研究和实践开辟了新的前景。本文介绍了一系列新问题以及有关高速公路交通的交通流建模，估计和控制开发，可在不断发展的交通环境中使用VACS。
