[Reporter Lin Minzhen/Taichung Report] Recently, Dingcuo Road and Lane 21, Dingcuo Road, Dali District, Taichung City have tried out smart road signs, which use radar microwave technology to detect incoming traffic on the main road, and then warn the LED signs on the branch lines to remind the public to "be careful when approaching the sideways" However, last night and today, the public found that it was "broken", and questioned "a deceitful facility? It broke down within a few days?" City councilor Zhang Fenyu found that the solar panels were out of power due to rainy days, and asked the traffic bureau to improve immediately. Otherwise it is too painty.
The Transportation Bureau responded that manufacturers have been asked to speed up improvements.
Zhang Fenyu said that Dingcuo Road and Lane 21 of Dingcuo Road are a T-shaped intersection. Due to the poor sight distance, passers-by on Lane 21 cannot see the vehicles coming from Dingcuo Road, the main road. For traffic signals, the Transportation Bureau chose to trial smart road signs on this road section to remind passers-by.
Zhang Fenyu said that the Bureau of Transportation explained this technology when the council held an extraordinary meeting. It mainly uses radar and microwave technology to detect incoming vehicle signals at main road intersections. Through the Internet of Things communication transmission system, the warning LED signs on the branch roads are activated, and the warning panels remind passers-by. There are cars on the main road, but there is no mention of solar panel storage.
Zhang Fenyu pointed out that at many intersections in Dali and Wufeng districts, the road width is narrow and the sight distance is poor. Reflectors, flashing lights, bouncing road surfaces, writing slow words, etc. are often used to remind passers-by, and smart road signs are introduced to remind them. Using passers-by is a good option, but after only 10 days of trial operation, the equipment "strikes" when it encounters rainy days due to the use of solar panels.
The traffic bureau must be required to improve, otherwise it would rather give up and choose a more effective method.
The Bureau of Transportation pointed out that in order to improve the problems of narrow roads and poor visibility at intersections, the Bureau of Transportation tried to implement smart road signs to increase driving safety at intersections. Smart road signs are powered by solar energy and do not need to be connected to mains power. The location is more flexible and the opening time is relatively short Fast and other advantages.
Considering that the solar energy may not be able to operate due to bad weather and insufficient power storage in recent days, the manufacturer has been asked to speed up the improvement. In addition, traffic signs and markings such as slow down and slow down have been set up on this road section. Maintain traffic safety.
People passing by the alleys with newly installed smart road signs thought that the device was malfunctioning.
