Table LED indication mark shorten read distance

Recently, Taiwan's Ministry of Transportation Highway in Zhongshan, Miaoli and Miaoli County Sanyi station 72 line pilot intelligent LED indicator to help traffic safety. It is understood that the luminous signs allow drivers to shorten the distance between the reading mark at night 1/3.

Many people have the experience of driving at night, because they can not see the signs, missed the intersection or exchange Road, some people even emergency brake or turn, very dangerous. Intelligent LED signs and LED combined with solar photovoltaic technology, the principle of sign visual distance from the traditional symbol of the 200 meters, increased to 1 kilometers, readable distance from 100 meters to 300 meters to increase, thus increasing the traffic safety.

It is understood that a set of intelligent LED costs about NT $240 thousand, 3 to 5 years to replace the battery, about NT $15000; the traditional symbol by lighting, set up fee of NT $60 thousand a year in electricity, NT $16425, 3 to 5 years to replace the lamp, lighting and security device costs about NT $50 thousand, cost analysis using 6 years both about NT $270 thousand, but 6 years later, the intelligent LED is far greater than the traditional benefits. Highway Administration second maintenance office Miaoli Public Works section chief Wu Zhizhong said that two years ago, line 72 took the lead in the 72 corners and use exchange road traffic signs, light effect is good, Miaoli Public Works section was evaluated by the Ministry of transportation to provide the first traveler information. "Ministry" in 2009 and then a subsidy of 15 million yuan NT, the traffic signs to large luminous signs, February 28th acceptance. In addition, the sign content arranged by the same brightness LED lights, signs of surface brightness average, detects rain or fog weather, can also start using solar energy automatic induction; 12 volts, no risk of leakage and electric shock.
