Abstract
Railways are the biggest transport system all over the world and also for any country too. It is the main backbone for transport system and hence railway safety is a crucial part of railway management system. Rail/road intersections are very unique, special, potentially dangerous and yet unavoidable in the World. One of the major safety aspects is the safe level crossings. Level crossing is a point at where a railway track and a road interact on the same level and these are characterized as manned (where man power is available) level crossings and unmanned (no man power in any from available) …show more content…

From the situation of current domestic and international railway crossing, crossing alarm technology is a major difficulty. A variety of alarm systems have been proposed previously, but all of them have some problems. Firstly, they have poor system stability and performance; secondly, the active sensors have some defects like this: instability and short reliable life cycle which would be replaced every two years, complex working principle, cost-ineffective, prone to failure, not convenient for the work. The system integrated with GPS and GPRS networks positioning, combined the advantages of the two and overcome the disadvantages of them, which made the performance improved significantly. It uses the satellite communication to locate the train positions and measure their …show more content…

The Railways are persistently following the steps to reduce unmanned level crossing accidents and no effort is made to dilute the gravity and the seriousness of accidents. In the control and scope of intervention in curbing unmanned level crossing accidents, the role of Railways is limited and highly constricted as most of them have been found occurring due to negligence on the part of road vehicle users. It is almost impossible for a train driver to stop and prevent the collision if he notices a road vehicle on the crossing from a distance of 500 to 600 meters nor is it possible to change the course of a train similar to that of road

    An introduction to highway building: Although there are many methods to constructing a road, all are based on the principle that geographical objects are removed and replaced with harder and more wear-resistant materials. The pre-existing rock and earth is removed by digging or explosions. Tunnels, embankments and bridge are then added when necessary. The material that the road is being constructed from is then laid by various pieces of equipment, which will be looked at in greater detail in this assignment. The construction management of roads has become increasingly more difficult as larger structures are constantly being required in increasingly short amounts of time.
