Investigation of Traffic Safety Situation at the Level Crossings in Lithuania

The Baltic Journal of Road and Bridge Engineering, 2013
Traffic safety assurance is the main task on roads as well as railways. At the level crossings both infrastructures cross each other. Therefore the problem of assuring the traffic safety at the level crossings remains permanently actual and is often ...

Landau-Zener problem in a three-level neutrino system with non-linear time dependence [PDF]

, 2006
We consider the level-crossing problem in a three-level system with non-linearly time-varying Hamiltonian (time-dependence $t^{-3}$). We study the validity of the so-called independent crossing approximation in the Landau-Zener model by making comparison

Prediction of Fatalities at Northern Indian Railways’ Road–Rail Level Crossings Using Machine Learning Algorithms

Infrastructures, 2023
Highway railway level crossings, also widely recognized as HRLCs, present a significant threat to the safety of everyone who uses a roadway, including pedestrians who are attempting to cross an HRLC.

Level-Crossing Optogalvanic Spectroscopy

Le Journal de Physique Colloques, 1983
Optogalvanic spectroscopy is applied to the detection of level -crossings at zero and finite magnetic fields. The method provides a sensitive, Doppler-free technique for determining hyperfine structures in both lower and upper levels of atomic transitions.

MODELLING THE RANKING OF LITHUANIAN RAILWAYS LEVEL CROSSING BY SAFETY LEVEL [PDF]

Transport Problems, 2017
The article describes the assessment of safety of Lithuanian Railways level crossing. The statistical analysis of the railway accidents in Lithuania and abroad in recent years has shown that about 30% of all transport accidents in railway occur at ...

Anomalous fermion number nonconservation: Paradoxes in the level crossing picture [PDF]

, 2006
In theories with anomalous fermion number nonconservation, the level crossing picture is considered a faithful representation of the fermionic quantum number variation.

The Born Oppenheimer wave function near level crossing [PDF]

, 2000
The standard Born Oppenheimer theory does not give an accurate description of the wave function near points of level crossing. We give such a description near an isotropic conic crossing, for energies close to the crossing energy. This leads to the study

Towards improving sustainability of rail transport by reducing traffic delays at level crossings: A case study for the State of Florida

Cleaner Logistics and Supply Chain, 2021
Rail transport makes a significant contribution to the economy of many geographical locations around the globe. Along with numerous merits, rail transport has some demerits as well, such as traffic delays and safety issues at level crossings.
