Railway operations are vulnerable to delays. Accurate predictions of train arrival and departure delays improve the passenger service quality essential for real-time railway traffic management minimise their further spreading. This review provides a synoptic overview discussion covering breadth diverse approaches predict We first categorise research contributions based on underlying modelling p...

Flight delays impose challenges that impact any flight transportation system-predicting when they will occur in a meaningful way to mitigate this issue. However, the distribution of delay system variables changes over time. This phenomenon is known predictive analytics as concept drift. paper investigates prediction performance different drift handling strategies aviation under scales (models t...

We provide a new event-triggered delay compensation approach for linear systems with arbitrarily long constant input delays. Our prediction map is expressible as solution of discrete time system. method ensures input-to-state stability. also an analog under measurement delays, where the continuous-discrete Significant novel features are our combined use matrices absolute values and based event ...

Flight delays have a negative effect on airlines, airports and passengers. Their prediction is crucial during the decision-making process for all players of commercial aviation. Moreover, the development of accurate prediction models for flight delays became cumbersome due to the complexity of air transportation system, the amount of methods for prediction, and the deluge of data related to suc...

It is important to clearly understand multipath propagation to develop high speed digital mobile communication system(l-$) . The r.m.s. delay spread can be directly obtained by measuring the delay profile. The problem has been that delay profi Ie measurements that are accurate must be taken for a wide frequency band. For example, with wideband measurement equipment using pseudo-noise signals, a...

While vehicular flows on freeways are often treated as uninterrupted flows, flows on arterials are conceivably much more complicated since vehicles traveling on arterials are not only subject to queuing delay but also to signal delay. Prediction of travel time is potentially more challenging for arterials than for freeways. This paper proposes a simple approach for arterial travel time predicti...

When traversing the earth’s neutral atmosphere, GPS radio signals are affected significantly by the variability of its refractive index, which causes primarily a delay, usually referred to in the literature as the tropospheric delay. An inaccurate modeling of this delay results in degradation of position estimates, affecting mainly the height component. The tropospheric delay is commonly divide...

Control of systems where the information between the controller, actuator, and sensor can be lost or delayed can be challenging with respect to stability and performance. One way to overcome the resulting problems is the use of prediction based compensation schemes. Instead of a single input, a sequence of (predicted) future controls is submitted and implemented at the actuator. If suitable, so...
