If the operator ignores the warning, brakes clench and the train stops - a precaution meant to head off driver-based accidents. Train operators can adjust speeds themselves, but a warning flashes if they exceed limits set for specific sections of track. Computers on trains, alongside tracks in special enclosures and at a new control center monitor a train's location and speed via radio waves.Īs in the subway systems in Washington, D.C., and London, screens installed in stations will tell riders when the next train will arrive. The new system uses "communications-based train control," or CBTC. With it, trains can run more closely together - and therefore more frequently - and with fewer accidents, transit officials say. Nabile Ghaly, NYC Transit's chief signal engineer, said the new system lets traffic controllers know exactly where each train is at all times, and it tightly controls train speed. If the program proves a success, it could take decades to implement the technology citywide. ![]() Studies on how to convert the L line began nearly 15 years ago, and more than $250 million has been spent so far on upgrading the L, chosen partly because it's among the shortest and doesn't share track with other lines. The passive, automatic flood barrier is established on an essential yet very simple concept - using the power of rising flood water against itself to protect your structure.Ĭontact Flooding Solutions for more information.The new technology is not without its critics, worried about safety. manufacturing and installation are vital for the success of the self-closing flood barrier, Flooding Solutions provides developers and proprietors with years of expertise for all stages of the process. Does have a minimal small surface "footprint"Īs only the top edge of the barrier is visible, it requires a very small surface "footprint" whereas other barriers that raise at 90 degrees from a floor structure require a surface area width at least equivalent to the flood protection height. When this happens, property damage and revenue loss can deeply impact the proprietors.ģ. Damaged seals can cause the flood barrier to fail during the critical time of a flood event. The hyflo SCFB has been designed without any exposed seals to avoid the potential risk of the seals being damaged by the harsh elements of the Australian climate. Does not have any exposed seals that can be affected by the elements. Any machine that does not have an exposed part also decreases the chance of injury.Ģ. There is a reduced risk of mechanical error during activation of the barrier. Does not have any exposed mechanical components that can fail in a flood event. ![]() What makes the self-closing flood barrier the best water powered flood barrier? It is the only water activated flood protection device that:ġ. The self-closing flood barriers are ideal for buildings, infrastructures and developments along the waterways and coastal areas, promenades, riverfronts and inland waterways or canals. Hyflo SCFB can typically last for a longer period of time, though the seals can be replaced with support from the Flooding Solutions Maintenance Team. The self-closing flood barrier can be used in combination with a permanent floodwall to prevent flood waters to get into a property. The use of passive flood barriers are recommended for flood proofing of commercial buildings and residential apartment buildings. The self-closing flood barrier doesn't need manual deployment, demounting or storage, and does not rely on electric or hydraulic controls, these aspects of its design remove the risks associated with human error, the need for human intervention, and concerns about electrical or hydraulic failure. The hyflo SCFB is a type of passive barrier that will activate automatically in a storm or flash flooding event, using the force of flood water to raise the barrier progressively as the flood waters rise. There are some consent authorities that have concerns regarding the small risk of failure associated with active flood protection devices.įlooding Solutions Advisory Group's Hyflo Self-Closing Flood Barrier embodies an innovative change in traditional flood control measures that eliminates these risks. Traditionally, the only method for protecting building entrances, driveway slopes, vent grills, and other defenceless paths have been active measures that require hydraulic and mechanical operating systems.
