A Data Transfer Model of Computer-Aided Vehicle Traffic Coordination System for the Rail Transport in Ukraine

چکیده
This paper gives a general layout of subsystem operation used for the rolling stock traffic coordination. A principle of selection of information technologies applied for the realization of the communication and data transfer system has been described. GSM and GPRS technologies that are used for the transmission of navigation information on a vehicle locus and for the information exchange in the system have been described. To provide a required level of transmission capacity through the frequency reuse the guard period between the base transceiver stations has been calculated. To calculate the GPRS channel capacity and that of information exchange via the Internet GPRS network an algorithm for the simulation modeling of packet arrival in the prescribed time space has been constructed. Using this algorithm an experiment was carried out for different intensity values of packet arrival to the system.

The ability to perform rolling contact fatigue (RCF) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. In this paper, a multi-body dynamics (MBD) model is proposed, simulating the vibration behaviour of the prescribed rig. The new testing facility is modelled using a three-dimensional model of the vehicl...

متن کاملMethod of Video-Measurements of Traffic Flow Characteristics at a Road Junction
In the theory of traffic flows the main characteristics are: intensity, speed, and density. They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...
