Ensuring electromagnetic safety at high-speed maglev transport

Electromagnetic Field Analysis and Modeling of a Relative Position Detection Sensor for High Speed Maglev Trains

The long stator track for high speed maglev trains has a tooth-slot structure. The sensor obtains precise relative position information for the traction system by detecting the long stator tooth-slot structure based on nondestructive detection technology. The magnetic field modeling of the sensor is a typical three-dimensional (3-D) electromagnetic problem with complex boundary conditions, and ...

On High Speed Transport Protocols

High speed applications require the use of a lightweight transport protocol. With the increasing transmission speeds up to the Gbps, the limitations appear at the control of the transmission and not on the capacity of the transmission link itself. Several protocols like XTP, NETBLT, the NADIR transport protocol or the Check Point Mode (CPM) were designed to overcome the inadequacy of \classical...

Ensuring Reliable Safety Standards

Safety impacts of signal-warning flashers and speed control at high-speed signalized intersections.

For many years, to reduce the crash frequency and severity at high-speed signalized intersections, warning flashers have been used to alert drivers of potential traffic-signal changes. Recently, more aggressive countermeasures at such intersections include a speed-limit reduction in addition to warning flashers. While such speed-control strategies have the potential to further improve the crash...

High-speed maglev noise impacts on residents: A case study in Shanghai

High-speed maglev trains offer competitive journey-times to automobile and air transport in markets of 60–1000 miles but they have potentially adverse noise impacts. This paper considers the noise characteristics of the Shanghai Maglev Train on residents within 300 m to the track. It shows that the system is about 4–8 dBA quieter than other high-speed systems at comparable speeds with their gui...
