Extraction of Critical Scenarios in a Railway Level Crossing Control System

open access: yesInternational Journal of Computers Communications & Control, 2007
This paper deals with the safety of the level crossing control system. We propose one way of the safety evaluation witch consist on the extraction of feared scenarios in the Petri net model of the system. We use ESA_PetriNet tool (Extraction Scenarios & Analyzer by Petri Net model) that was developed in the aim of extraction of feared scenarios

Developing a universal tunnel span classification from global tunnel databases

open access: yesDeep Underground Science and Engineering, EarlyView.
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.

Damage Characteristics and Stress Distribution Law of Overburden Rock in Multiple Mining of Close Coal Seams

open access: yesEnergy Science &Engineering, EarlyView.
This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Motorist behaviour at railway level crossings: An exploratory study of train driver experience

open access: yes, 2005
Railway level crossings are the interface between roads and train lines, and as such are the potential site for vehicle-train collisions and incidents. Of all road crash types, those between motor vehicles and trains are amongst the most severe. However,
