摘要： 面向发展智能网联汽车的国家重大战略，基于智能驾驶对交通管控的数字化要求，提出一种 道路数字空间指挥调度语言——交通指挥数字信号。通过平台侧与路侧两条管控路线协同的交通数 字化交互控制模式，实现通行权实时分配信息及其预期时变特征向智能网联汽车的精准传达，显著 提升车辆在道路/车道通行权动态识别、超视距冲突风险感知和通行权变化预期管理等方面的能 力，有效保障交通运行的有序、安全与高效，同时优化驾乘体验的个性化与自主化。该数字信号技 术路径已在无锡市“车路云一体化”试点中完成152 个道路交叉口的规模化验证，实测实现百毫秒 级车道级信号推送，并计划于2025年开展无锡市全域标准化应用示范。

Abstract： Facing the major national strategy of developing intelligent connected vehicles, a command and dispatch language in the digital space of road networks, which called Digital Signals, is proposed to meet the intelligent driving's digital requirements for traffic control. Based on the two routes of traffic digital interactive control, namely the platform side and the road side, realtime allocation and dispatch information of different right-of-way and its expected time-varying characteristics will be conveyed to intelligent connected vehicles, helping them to enhance capabilities in dynamic identification of road/lane right-of-way, perception and cognition of beyond-visual-range conflict risks, and expectation-management of right-ofway changes. This ensures orderly, safe and efficient vehicle passage and enhance personalized and autonomous driving experiences. The digital signals technical pathway has been verifed on a large scale at 152 road intersections in the“Vehicle-Road-Cloud integration”pilot project in Wuxi. It has been measured to achieve lane-level signal push within a hundred milliseconds. It is planned to carry out a standardized application demonstration throughoutWuxi in 2025.
