The Designation of a New Kind of Green Streetcar Based on Virtual Tracks and Key Technologies

Article Preview

Abstract:

As the development of urbanization and economy, the traffic stresses in most urban cities in China have many severe challenges that need solving in the process. The idea of a new kind of streetcar based on virtual tracks which owns a series of advantages including suitable speed, big capacity, low construction cost and environmentally friendly is proposed. The designation of the streetcar is moving around the aim of a capacity of 15 thousand persons per hour with the operation speed of 40~50km/h. The key technologies are consists of the identification and navigation of the virtual tracks, differential steering theory, vehicle system dynamics, suspension system, precise control of wheel hub motor and the right of way rules (ROW). This article describes technical principles of each key technology and their latest development in the progress of the green streetcar based on virtual tracks.
