Railway traffic controllers have only limited decision support to deal with disruptions. The aim of this research is to provide an algorithm to compute conflict-free routes for trains that cannot continue their planned operation due to a track obstruction. In case of complete blockage, trains need to short-turn at the closest possible station to the disturbed area and provide services in the op...

The main objective of this study is to present a framework developed for assisting Railways to monitor and control the quality of services provided to passengers. The study evaluated the passenger Rail Service quality of Indian Railways by developing SQM (Service Quality Management) model on the basis of SERVQUAL and Rail Transport quality. Three new dimensions (Service Product, Social Responsi...

Data from available literature point to an early beginning of Forensic Dentistry in Croatia relating to a post-mortem examination of a female patient after a dental procedure in the 1930s. Later on, there were several mass casualties due to collisions and airplane crashes and a railway accident at the Zagreb Main Railway Station wherein the identity of the victims was established based on denta...

This paper provides an overview of the DITTO (Developing Integrated Tools to Optimise) project and presents some of its initial findings. The aim of DITTO is to increase the practical capacity of railway systems by developing computerised tools that can determine the theoretical capacity of a given infrastructure, optimise timetables in the face of delays and optimise real-time traffic manageme...

The train timetabling problem considered is to find conflict free routes for a set of trains in a given railway network so that certain time window conditions are satisfied. We deal with the very large scale problem of constructing such timetables for the German railway network. A number of restrictions on different train types like freight trains or passenger trains have to be observed, e.g., ...

The Yinchuan–Chongqing high-speed railway (HSR) is one of the “ten vertical and ten horizontal” comprehensive transportation channels in National 13th Five-Year Plan for Mid- Long-Term Railway Network. However, choice node stations on this line controversial. In paper, problem station selection transformed into a classification under edge graph structure complex networks, Scatter-GNN model prop...

planning of air pollution control programs need knowledge of pollutants emitting sources; the department of environmental health, school of public health, tehran university, performed an air monitoring program for a period of six months in 1976-77. a daily sampling was done from 8 a.m. to 8 p.m., at ten different stations in metropolitan tehran. saltzman's sampling and analysis procedures were ...

today’s transportation is known as one of the most important elements of urban development structure. public transportation, according to its more extensive functional capacity, can play a vital role in wider scale. transit oriented development by focusing on the subways is one of the special approaches in this field. recently, tehran public transport fleet has significantly improved especially...
