In everywhere at level crossing between railroad and highway there are so many railway accidents happening due to the carelessness in manual operations or lack of workers. So, this paper describes the automatic railway gate control system using PIC microcontroller for saving precious human lives and preventing major disasters in railway track. Railway gate may be saved for the road users to pre...
BACKGROUND Railway suicide has significant adverse impacts for the victims, their family and friends, witnesses to the incident, general public and train network. There is no previous review on the socio-environmental factors and railway suicide. The research question asked in this review was: 'What socio-environmental risk and protective predictors are significantly associated with railway sui...
BACKGROUND Railway suicides strongly impact psychological and socioeconomic aspects of the railway company, its employees and possible eye witnesses. We aimed to assess the incidence of railway suicides compared with the total burden of suicides in Germany and its time trend over a 10-year observation period. METHODS From 1991 to 2000, a total of 8,653 fatal railway suicides were recorded by ...
BACKGROUND In 2010, the "Tackling Suicide on the Railways" programme was launched as a joint initiative among Network Rail, the Samaritans and other key organisations such as the British Transport Police and train operators to achieve a 20% reduction in railway suicides from 2010 to 2015 in Great Britain. We report the most recent age and sex specific trends in railway suicide in England and Wa...
We consider how to improve railway timetables. As case we take the Rompnet of the dutch railways, a highly constrained problem, containing both hard and soft constraints. We show how to cast the constraints into the format of the Genocop system. Every train should run every hour at the same time and hence the constraints should be interpreted modulo sixty. This gives a non-convex search space o...
Signalling, a complex system is one of the most important infrastructures of railway service. The performance of railway signalling system depends on the functioning of a number of subsystems, such as panel, cable, relay, point and point machine, trackcircuit, signal, back indication, point-drive card, signal-drive card, and level crossing gate. Railway signalling system plays an important role...
Recently, the railway system is advancing to be intelligent according to the development of computer technology, and especially, many functions of train control system which are cores to the railway system are being operated by the software. Accordingly, the source code testing to validate safety of the railway train control system software becomes to be more important, and related internationa...
Bicycling crashes on streetcar (tram) or train tracks: mixed methods to identify prevention measures
BACKGROUND Streetcar or train tracks in urban areas are difficult for bicyclists to negotiate and are a cause of crashes and injuries. This study used mixed methods to identify measures to prevent such crashes, by examining track-related crashes that resulted in injuries to cyclists, and obtaining information from the local transit agency and bike shops. METHODS We compared personal, trip, an...
In today’s business world whose characteristics include limited financial resources it is critical to identify and monitor where and how these resources need to be invested in the company. The Master Budget represents a plan of action which specifies how financial resources will be acquired and invested during a particular time period. Activity-Based Budgeting (ABB) is a budgeting approach that...
Most railway accidents happen at railway crossings. Therefore, how to detect humans or objects present in the risk area of a railway crossing and thus prevent accidents are important tasks. In this paper, three strategies are used to detect the risk area of a railway crossing: (1) we use a terrain drop compensation (TDC) technique to solve the problem of the concavity of railway crossings; (2) ...
