The paper 'Alarm Control Systems at Railway Level Crossing Junctions" is a great example of an engineering and construction research proposal. Accidents occurrence at level crossings remains an issue of concern to the modern world. This article highlights a circuit solution specifically tailored for controlling alarm systems with a failsafe mode in order to resolve issues that have been arising from the failure of alarm notification systems. The methodology of approach deploys patented solutions which are slightly modified to solve this problem. It is recommended that the failsafe mechanism be incorporated in all alarm control systems as an approach towards solving this problem. Introduction Road safety at level crossings still remains an issue of concern in the modern world 200 years after the inception of railways.
It has been established that level crossing safety has continued to be compromised due to road drivers’ negligence. The potential danger that level crossings pose to the road users is not emphasized due to the unawareness that a train could be coming from the other side of the rail any time. Comparing level crossing to a train station that is full of action level crossing pose danger to human life and other forms of destruction due to complacency.
Late detection has also been questioned due to the errors that arise from critical alarm failures and many other forms of undocumented failures. In order to make sound decisions prior to crossing at a level crossing, drivers are provided with road signs that are dedicated towards this form of notification. This report, however, dwells on the electronic form of notification (digital alarm) in order to deal with this road ordeal.
The circuit is designed to show the uniqueness that should be instilled in the new system that is meant to curb accidents at a level crossing. Research The existing alarm notification systems are meant to raise an alarm once the train is within the proximity of the sensors. This does not offer an integrated approach through a multifaceted system approach to ensure a failsafe system. According to Khoudour, et al. (2008) in a study meant to reduce the incidences faced by level crossing in the European Union region, it was established that some of the human causes of accidents at the level crossing are due to distracted blindness in which absence of attention leads to failure to perceive an oncoming object.
This has also been a cause of the accident for most road users thus it is also expected for the level crossings too. Road users tend to have an expectation based mentality to the extent that they fail to respond in a way to protect themselves against the manifesting environment. Further to the two causes of level accidents above, it has also been established that perceptual limitations gather the majority of information than visual systems.
Speed and distance perception has also been raised as the main issue that is associated with level crossing accidents. Tinakaras (2014) affirms to the distance and accuracy issue stating that accurate decision making when it comes to the level crossing is affected greatly due to the complex perceptual process that involves two moving objects that are expected to converge at a given point.
