China News Service, April 9, According to Taiwan's China Times, Taiwan's first Zhongheng Highway , which crosses the central mountain range of . For more than 60 years, the rock formations of mountain walls have caused frequent occurrences of large and small rocks due to terrain weathering. Taiwan's "General Administration of Highways" has built a rock fall warning system in the Xibao section of Zhongheng. It is expected that after completion by the end of April, it will be possible to detect the impact of rock falls through early warning facilities, and simultaneously issue warning messages to monitor road safety all day long.

The temperature drop is large, causing the soil and rock to loosen
Taiwan Eighth Line Zhongheng Highway has about 4 million passengers every year. Due to the Zhongheng Highway from Taroko to Dayuling , the height drop changes by 2,500 meters. In addition, there are often thunderstorms in the mountainous areas in the afternoon, resulting in the thermal expansion and contraction of the soil and rocks on the slopes that are very easy to loosen. There are often sporadic rocks falling on the road surface. Passengers or vehicles are repeatedly reported to be injured by rocks falling every year.
In order to improve the safety of Zhongheng Highway and improve the fall of rocks in mountainous areas for many years, the "Highway Administration" has included 34 sections of rock-falling on Zhongheng Highway, and invested NT$20 million in 2018. A rock-fall warning system was set up in the Xibao section, which is 159.7 kilometers away from falling rocks, and related protection projects have been carried out one after another, hoping to effectively reduce the rate of disasters caused by rocks.
briefing real-time notification of disaster situation 0 hour difference
Taroko Department Director Zhang Yubo said that the rockfall warning system that will be completed before the end of April will first buffer and block the rockfall from falling to the road through the rockfall protection network . At the same time, the rockfall impact energy is measured through the early warning facilities to analyze the changes in the stone cable and pillar of the stone net, and predict that the message will be transmitted to the outside in real time after the rockfall is informed.
terminal transceiver station will automatically inform relevant managers with a brief message. After receiving the notice, it will provide the police in the jurisdiction simultaneously. Through the highway on-site warning facilities and CMS system, passers-by can react early, and can also be used as a basis for road closure decisions. At that time, through technological early warning, intelligent disaster prevention and control will be used to check the safety of Zhongheng road usage.
