A deep learning-based safety monitoring framework for air traffic control (ATC) systems is proposed in this paper to reduce human errors and relieve the controllers' workload by regulating controlling procedure, eliminating communication misunderstanding, flight conformance, detecting potential conflicts. The comprises automatic speech recognition (ASR), intent inference (CII), (CSM) subsystems. pipeline of can be described as follows: ASR subsystem translates pilot-controller voice...

This work focuses on robust speech recognition in air traffic control (ATC) by designing a novel processing paradigm to integrate multilingual into single framework using three cascaded modules: an acoustic model (AM), pronunciation (PM), and language (LM). The AM converts ATC phoneme-based text sequences that the PM then translates word-based sequence, which is ultimate goal of this research. LM corrects both phoneme- errors decoding results. AM, including convolutional neural network (CNN)...

In order to improve the accuracy and robustness of air traffic prediction, in this paper, a recurrent 3D convolutional neural network (R-3DCNN) based model is proposed consider spatial temporal transitions comprehensively. A new data representation, i.e., situation graphics (TSG), firstly illustrate flow situations single instant. TSG generated by splitting earth space with fixed grid map flight levels. Motivated applications deep network, CNN long short-term memory (LSTM) blocks are...

Automatic Speech Recognition (ASR) is greatly developed in recent years, which expedites many applications on other fields.For the ASR research, speech corpus always an essential foundation, especially for vertical industry, such as Air Traffic Control (ATC).There are some corpora common applications, public or paid.However, ATC, it difficult to collect raw speeches from real systems due safety issues.More importantly, a supervised learning task like ASR, annotating transcription more...

In this work, a deep Gaussian process (DGP) based framework is proposed to improve the accuracy of predicting flight trajectory in air traffic research, which further applied implement probabilistic conflict detection algorithm. The distribution serve as representation for illustrating transition patterns trajectory, on stochastic generated build temporal correlations among positions, i.e., (GP). Furthermore, deal with maneuverability performing controller’s instructions, hierarchical neural...
