Peter POČTA was born in 1981. He received his M.S. and Ph.D. degrees from University of Žilina, Faculty of Electrical Engineering, Slovakia in 2004 and 2007, respectively. During his Ph.D. study, he was awarded a number of fellowships. Firstly, he spent 3 months as an Erasmus student in the Department of Electrical Engineering and Information Technology, Chair of Telecommunications of the Dresden University of Technology, Germany where he collaborated on testing principles over ADSL access lines. Secondly, he was with Alcatel-Lucent, R&D center, Network Integration department, Stuttgart, Germany where he investigated some impacts on speech quality in WiMAX system. He is currently an Associate Professor at the Department of Multimedia and Information-Communication Technology of the University of Žilina and is involved with International Standardization through the ETSI TC STQ as well as ITU-T SG12. His research interests include speech, audio, video and audiovisual quality assessment, speech intelligibility, multimedia communication and QoE management. He has published over 60 refereed papers in international journals and conferences including Acta Acustica united with Acustica, Advances in Multimedia (Hindawi), AEÜ - International Journal of Electronics and Communications (Elsevier), Speech Communication (Elsevier), IEEE Transactions on Broadcasting, MESAQIN and QoMEX conferences. He serves as an external reviewer for the Journal of Systems and Software (Elsevier), Computer Standards&Interfaces (Elsevier), Speech Communication (Elsevier), Telecommunication Systems (Springer), Quality and User Experience (Springer) and IEEE/ACM Transactions on Audio, Speech and Language Processing and several conferences in area of multimedia quality and communication networks, e.g. QoMEX, QCMan, etc.
Supervisors: Ralf Lehnert (TU Dresden) and Martin Vaculik (University of Zilina)

The Effects of Vehicle-to-Infrastructure Communication Reliability on Performance of Signalized Intersection Traffic Control

ArXiv, 2021

A vehicle-to-infrastructure communication can inform an intersection controller about the locatio... more A vehicle-to-infrastructure communication can inform an intersection controller about the location and speed of connected vehicles. Recently, the design of adaptive intersection control algorithms that take advantage of this information evoked a lot of research, typically assuming a perfect communication. In this study, we explore possible effects of a temporal decrease in the reliability of the communication channel, on a throughput of a signalized intersection. We model road traffic and DSRC-VANET communication by integrating the well-established traffic and communication simulation tools (Vissim and OMNeT++). Comparisons of the perfect communication conditions with challenging, but realistic conditions involving communication distortions show that the adaptive intersection control may suffer from significantly increased average delays of vehicles. The level of delays is largely independent of whether the communication distortions affect all or only a single intersection approach....
