Automatic Boom Barriers Announced For Yangon Railway Project

boom barrier, also recognized as a boom gate, is the bar, or pole pivoted to permit the boom to obstruct vehicular entrance through a controlled point. Characteristically, the tip of a boom gate rises in a vertical arc to a near vertical position. Boom gates are frequently counterweighted, so the pole is simply tipped. Boom gates are frequently paired either end to end, or offset suitably to block traffic in both of the directions. A number of boom gates also have a second arm which hangs 300 to 400 mm under the upper arm while lowered, to boost advance visibility, and which hangs on links so it lies flat with the main boom as the barrier is raised. A number of  the barriers also feature a pivot roughly half way, where as the barrier is lift up, the outermost half remains horizontal, with the barrier similar to an upside-down L while raised.

There are a variety of technologies for an automatic boom barrier gate. One of them is an electro-mechanical, which is extensively used due to its dependability. The other technologies are often manufacturer specific. These electro-mechanical devices come with the 24VDC drive unit which can run incessantly without producing the heat, so electro-mechanical boom barriers can work continuously in an intensive duty cycle.

Operation of automatic boom barrier

An Automatic boom barrier is made up of the following components:

  • The Push Button
  • The Remote Control
  • RFID Tags and RFID Reader
  • The Loop Detectors
  • Any third party right to use control device

Boom gates are classically found at Level crossings, the drawbridges, the parking facilities, checkpoints as well as entrances to restricted areas. They are also the natural method for controlling the passage through the toll booths, and it can also be found on a number of freeway entry ramps which are routinely controlled to drop to limit traffic in the event of the accident cleanup or the road closures without the necessity to dispatch the road workers or law enforcement agency to use a vehicle to block the way. A number of boom gates are automatic as well as powered, others are hand operated. Manual gates are from time to time hung in the manner of the normal gate. In a number of places, boom gates are installed across the suburban streets as a traffic calming measure, preventing the traffic, whilst allowing authorized vehicles such as emergency services as well as buses to take advantage of the shorter as well as more direct route.

For a city with an expected population of six million like that in Yangon experiences increasingly congested roads, the intra-city railway line has to counter the hustle and bustle. This is chiefly due to the fact that the train travels at about 17 kilometers an hour therefore it takes nearly three hours to finish the 45.9 kilometer route, which includes the 39 stations. The fine news is that plans to modernize the circle line are in the pipeline – but the depressing news is that this will take at least six years from now to finish.

A level crossing, or the grade crossing, is an intersection where a railway line crosses a road or path at the same level, as opposed to the railway line crossing over or under utilizing abridge or tunnel. The term also applies while a light rail lines with separate right-of-way or the reserved crosses a road in the similar fashion. Other names consist of railway crossing, road through railroad, railroad crossing, as well as train crossing.

Railroad trains have a huge mass relative to their braking ability, thus they need a far longer braking distance than road vehicles. In general, trains do not stop at level crossings but rely on the vehicles as well as pedestrians to clear the tracks in advance.

Level crossings comprise an important security concern internationally.  Contemporary radar sensor systems can detect if level crossings are free of obstacles as trains approach. At the railway stations, a walker level crossing is sometimes offered to permit passengers to reach other platforms in the absence of an underpass or the bridge. Where third rail systems have level crossings, there is a gap in the third rail over the level crossing, but this does not disrupt the power supply to trains while they have current collectors on the manifold cars.
