Sydney From The Warf

SYDNEY (Reuters) - Asian shares got off to a positive start on Thursday after data showed Japan's economy accelerated in the first three months of the year, in contrast to an enduring recession in the euro zone which was keeping the euro in the doldrums.

Developed and implemented back in 2011, Laservision's Softstop system projects a familiar bright red stop sign, seemingly in mid-air, at the tunnel's entrance if a vehicle too large to enter is detected. In fact, the stop sign does not float in mid-air, but rather is projected onto a water screen that, should a vehicle not heed its command, would cause no damage from being driven through. The Softstop water stop sign is a last resort, mind you. If a driver's truck is tall enough that it would crash into the tunnel were it to enter, a number of brightly flashing warning signs are activated that signal the driver to stop earlier. Only if those flashing signs are ignored is the Softstop system activated at the tunnel's entrance. Likewise, the Softstop system can be activated for other reasons, including keeping drivers out for their own protection if there's a fire or other disaster inside the tunnel. Though we admit to chuckling at the occasional truck-crashes-into-low-overpass video (11foot8.com is a whole website devoted to vehicles crashing into a low railroad trestle in Durham, NC), this clever solution for preventing such accidents is even more interesting to watch in action.Continue reading Clever water stop sign prevents tunnel crashes in AustraliaClever water stop sign prevents tunnel crashes in Australia originally appeared on Autoblog on Wed, 15 May 2013 17:00:00 EST.
