Title: Virtual rail intelligent express system

Abstract: Due to the role of track guidance, bearing and constraint, rail trains have the advantages of large volume and high efficiency, and have been the backbone of urban transportation for a long time. However, due to the harsh smoothness and other requirements of the track, the system construction, operation and maintenance are complicated and costly. Therefore, the industry has been exploring new types of trains, simplifying the requirements of vehicles on the track structure, and innovating straddle-type monorail trains, guideway type rubber trolleybuses, etc., so as to change the solid track from double track to monorail. Whether the dependence on the physical track can be completely overturned is a new technical challenge.

The virtual track intelligent express system is the first to create a new multi-group articulated rubber-tyred train based on the virtual track, which completely replaces the physical track through technologies such as path perception and active guidance control. Since 2010, it has undergone an iterative innovation process such as concept research, principle verification, prototype testing, and engineering demonstrations, it made its world premiere in 2017.

This system creates a new rail transit system, which can be widely used in the network connection or extension of metropolitan rail transit, the construction of backbone transportation systems in small and medium cities, and the operation of special lines such as tourist attractions. Compared with trams, the overall cost is only about 1/3, the construction period is only about 1/2, it can be flexibly configured and quickly form a transportation network. Taking the 17.7km T1 line of Sichuan Yibin, where the system is applied, as an example, it saves about 1.7 billion yuan in investment compared with the tram system. In the year of opening (2019), the city was promoted to rank first in the congestion reduction rate in China. At present, the system has successfully passed the extreme cold and high heat extreme tests in Harbin and Qatar, and has become the traffic (connection) solution for the 2022 World Cup.

The emergence of this system has injected strong original innovation power into the diversified and deep development of the world’s rail transit. It has outstanding characteristics and obvious advantages. It has a broad market application space in the future and has great potential for sustainable development.
