ITS-G5 Channel Models for High Speed Train-to-Train Communication
نویسندگان
چکیده
Train-to-train communication will be the key technology for future railway operation. An increase of safety and efficiency can be achieved by exchanging data between trains via ad hoc networks. For vehicle-to-vehicle communication the European standard is intelligent transport systems (ITS-G5). The usage of this standard for railways is hardly investigated. We investigate the performance of ITS-G5 for trainto-train communication at high speed conditions. ITS-G5 units were installed on two high speed trains and train-to-train (T2T) measurements were performed between Naples and Rome during four nights to cover different maneuvers. We present the analysis of the measurements data and resulting path loss models for tunnel and open field environments.

Parameters Assignment of Electric Train Controller by Using Gravitational Search Optimization Algorithm
The speed profile of the train will be determined according to criteria such as safety, travel convenience, and the type of electric motor used for traction. Due to the passengers and cargo on the train, the electric train load is constantly changing. This will require reassigning the speed controller’s parameters of the electric train. For this purpose, the Gravitational Search optimization Al...
متن کاملHigh-speed railway channel measurements and characterizations: a review
Wireless communication for high-speed railways (HSRs) that provides reliable and high data rate communication between the train and trackside networks is a challenging task. It is estimated that the wireless communication traffic could be as high as 65 Mbps per high-speed train. The development of such HSR communications systems and standards requires, in turn, accurate models for the HSR propa...

Speed is the created air flow as well as slipstream effects as the trains move. These effects can have some level of impact on fuel and energy efficiency of the train, but their other important outcome is the emergence of turbulent flows at higher speeds which can cause aerodynamic drag forces followed by noise and vibration. Thus, slipstream effects have significant importanc...
