Development Course Overview and Future Prospect of Road Rubber-tyred Guidance System

[目的]路面胶轮导向系统已在世界上部分城市开通运营。为了更详细、更全面地认识该系统,有必要对其发展历程及不同发展阶段的技术特点进行系统总结。[方法]从路面胶轮导向系统的导向方式和编组模式两方面,将该系统的发展历程分为4个阶段——1.0阶段、2.0阶段、3.0阶段及4.0阶段。逐个分析了每个阶段路面胶轮导向系统的主要技术特征、应用场景及应用案例,对各个阶段呈现出的不同技术特点进行了总结。对路面胶轮导向系统未来的5.0阶段进行了展望。[结果及结论]该系统4个阶段的发展历程是逐步实现无导向到刚性导向、刚性导向到柔性导向、单编组到多编组的过程,呈现出运行方式轨道化、基础设施简易化、导向模式智能化、车道使用复合化、编组模式增量化的发展特点。5.0阶段的系统应具备虚拟编组、柔性导向的技术特征,干线路段通过车辆之间的虚拟连挂增加运量、提高运输效率,以满足具有“一干多支”特点的城市公共交通出行需求。

[Objective]Road rubber-tyred guidance system is officially launched for operation in some cities worldwide.To gain a more detailed and comprehensive understanding of this system,it is necessary to systematically summarize its development history and technical characteristics at different stages.[Method]According to the guidance methods and formation modes of the road rubber-tyred guidance system,the development of which can be divided into four stages:Stage 1.0,Stage 2.0,Stage 3.0 and Stage 4.0.The main technical characteristics,application scenarios and application cases in each stage are analyzed individually.The distinct technical characteristics exhibited in each stage are summarized.A prospective analysis of Stage 5.0 for future road rubber-tyred guidance system is provided[Result&Conclusion]The development course of this system through the four stages represents a gradual progression from non-guided to rigid guidance,from rigid guidance to flexible guidance,and from single formation to multi-formation,demonstrating characteristics of orbitalized train operation mode,simplified infrastructure tendency,intelligent guidance mode,composite vehicle lane use,and incrementing formation mode.The Stage 5.0 system should possess technical characteristics of virtual formation and flexible guidance.Trunk line sections,through virtual coupling between vehicles,will increase transport capacity and enhance transportation efficiency,meeting the needs of urban public transportation with the characteristics of′one-trunk multi-branch′.
