A New Form of Train Detection as a Solution to Improve Level Crossing Closing Time [PDF]
The critical points on the rail and road network are their intersections, i.e., level crossings. During a train crossing, car traffic is stopped. This reduces the fluidity of traffic on the road and, consequently, can cause congestion.

Nonlinear level crossing models [PDF]
We examine the effect of nonlinearity at a level crossing on the probability for nonadiabatic transitions $P$. By using the Dykhne-Davis-Pechukas formula, we derive simple analytic estimates for $P$ for two types of nonlinear crossings. In the first type,

Level Crossing Along Sphaleron Barriers [PDF]
In the electroweak sector of the standard model topologically inequivalent vacua are separated by finite energy barriers, whose height is given by the sphale\-ron.

Object Detection at Level Crossing Using Deep Learning [PDF]
Multiple projects within the rail industry across different regions have been initiated to address the issue of over-population. These expansion plans and upgrade of technologies increases the number of intersections, junctions, and level crossings.

Simple rules for resolved level-crossing spectra in magnetic field effects on reaction yields [PDF]
In this work we derive conditions under which a level-crossing line in a magnetic field effect curve for a recombining radical pair will be equivalent to the electron spin resonance (ESR) spectrum and discuss three simple rules for qualitative prediction

Level Crossing for Hot Sphalerons [PDF]
We study the spectrum of the Dirac Hamiltonian in the presence of high temperature sphaleron-like fluctuations of the electroweak gauge and Higgs fields, relevant for the conditions prevailing in the early universe.

Level Crossing Rate of Macrodiversity System in the Presence of Multipath Fading and Shadowing [PDF]
Macrodiversity system including macrodiversity SC receiver and two microdiversity SC receivers is considered in this paper. Received signal experiences, simultaneously, both, long term fading and short term fading.

Level crossings as bottlenecks [PDF]
Level crossings represent bottlenecks from the aspect of vehicle capacity as one of basic parameters for traffic flow. From the railway traffic aspect they represent weak points on railway tracks due to rails exposure to the dynamic influence of road ...

AN APPLICATION OF THE AHP METHOD FOR EVALUATION OF LEVEL CROSSING DESIGN IN A CONGESTED URBAN AREA: CASE STUDY LC SOKOLSKA IN ZAGREB, CROATIA [PDF]
The AHP method(Analytic Hierarchy Process), as a part of the Multi- Criteria Decision-Making (MCDM) process, is one of the most used methods worldwide for dealing with the complexity of transport project evaluation.
