Phantomatic Road Works in Poland: A View from a Dashboard Cam
Transport and Telecommunication, 2023 Correct signage belongs to critical factors affecting road traffic safety. During a naturalistic driving study in Poland major mistakes associated with signage were noticed and analysed: road works were announced and speed limits were reduced from 120 km/

Speed limit for open quantum systems
New Journal of Physics, 2019 We study the quantum speed limit for open quantum systems described by the Lindblad master equation. The obtained inequality shows a trade-off relation between the operation time and the physical quantities such as the energy fluctuation and the entropy ...

Traffic Safety Research, 2022 As crash speed increases, so does the probability of injury. The vulnerability of different road users varies greatly, in part due to differences in their protective equipment. Therefore, for the same speed, their injury probabilities are different.

Quantum speed limits for observables
Physical Review A, 2022 In the Schr{ö}dinger picture, the state of a quantum system evolves in time and the quantum speed limit describes how fast the state of a quantum system evolves from an initial state to a final state. However, in the Heisenberg picture the observable evolves in time instead of the state vector.

How accurate is the regional travel demand model in mimicking real-world travel times?
Urban, Planning and Transport Research, 2019 This paper provides insights pertaining to the validity of a regional travel demand model in mimicking real-world travel times. The estimated travel times from the regional travel demand model, for the base year 2015, for Mecklenburg County in the city ...
