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 ...

Level Crossings of a Cauchy Process
The Annals of Probability, 1986 The authors use the well-known skew-product representation of planar Brownian motion, and a simple argument involving Brownian scaling and renewal theory for an embedded random walk, to establish the asymptotic behaviour of numbers of large, small, and medium crossings of zero by a Cauchy process. They further apply the results of a comparison paper to

Level Crossings for Random Fields
The Annals of Probability, 1976 For an $n$-dimensional random field $X(\mathbf{t})$ we define the excursion set $A$ of $X(\mathbf{t})$ by $A = \{\mathbf{t} \in \mathbf{I}_0: X(\mathbf{t}) \geqq u\}$, where $I_0$ is the unit cube in $R^n.$ It is shown that the natural generalisation of the number of upcrossings of a one-dimensional stochastic process to random fields is via the ...

Level crossing along sphaleron barriers [PDF]
Physical Review D, 1994 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. For large values of the Higgs mass there exist several sphaleron solutions and the barriers are no longer symmetric.

LEVEL CROSSING SAFETY IN THE CZECH REPUBLIC
Acta Polytechnica CTU Proceedings, 2017 This paper describes safety threats at level crossings according to the different type of security equipment. Initially were explored statistical data, which consist of numbers of level crossings classified by crossing type and numbers of traffic ...

Diagnostyka, 2021 At level crossings equipped with automatic level crossing signalling devices (which are category B and C crossings in Poland), warning time depends on several factors including the length of what is referred to as the level crossing’s danger zone for ...

LIGHTING ON UNREGULATED PEDESTRIAN CROSSING
Вестник СибАДИ, 2019 Introduction. The actual problem in Russia is the accident rate at pedestrian crossings. The authors conduct the research about the lighting conditions on unregulated pedestrian crossings to improve safety and to identify compliance with current ...

Microscopic Traffic Characterization of Light Rail Transit Systems at Level Crossings
Advances in Civil Engineering, 2021 The movement of the light rail vehicles (LRVs) is highly interrupted at level crossings during peak hour times, especially when the intersections are not regulated by a coordinated signal system.

An AHP model for level crossing design [PDF]
International Journal of Safety and Security Engineering, 2018 Level crossings (LC) are places of rail and road intersections and therefore areas with increased risk of severe accidents. The main objective of this study is to apply the multi-criteria Analytical Hierarchy Process (AHP) method to evaluate the variants for the reconstruction of LCs in an urban environment through weighting of various criteria and sub-
