In recent years, Shanghai has vigorously promoted energy-saving lighting. The use of intelligent street lighting energy-saving control is the latest energy-saving technology. Since the electricity load of the whole city is reduced in the middle of the night, the grid voltage is higher than the standard voltage. At this time, the street lamp will operate at a super power level, becoming extremely bright and dazzling, and increasing unnecessary power consumption. The intelligent street lamp energy-saving control technology dynamically and intelligently controls the street lamp illumination through step-down, voltage regulation and voltage regulation. In the middle of the night, the road traffic was heavy, the street lights kept strong illumination, and the voltage was automatically reduced at midnight to maintain the lower illumination of the street lamps. The Shanghai Street Lamp Management Office tested 72 ç› 250 watt high-pressure sodium lamps on Zhaojiatun Road and Shaanxi South Road. Under the control of intelligent energy-saving control system, the street lamps were operated at 11 o'clock in the evening, and the electricity was saved after 11 o'clock in the morning. The mode operates, saving nearly 50 kWh of electricity in one night, and the energy saving rate is 20.6%. It is reported that all the street lights on the Damuqiao Road, Caoyang Road, Xincun Road, Wuning Road and the Central Line have adopted this technology. Carefully calculate the account, if the technology is extended to the whole city, the annual electricity saving fee is about 28.51 million yuan.
In contrast, Shanghai's road sign replacement project is much more extravagant:
The unified numbering and naming of highways nationwide is gradually unfolding, and the replacement of street signs is also reasonable, and Shanghai is no exception. According to reports, about 5,000 street signs in Shanghai need to be replaced, and it costs 200 million yuan, which caused Han Han to question and call it "the most expensive iron sheet." Netizens have forwarded.
"A piece of iron sheet, spray paint to 40,000"
According to Shanghai media reports, Zuo Tianfu, deputy head of the Shanghai Public Security Bureau Traffic Police Corps, revealed that in order to coordinate the number adjustment, about 5,000 road signs in Shanghai will need to be adjusted and replaced. Including the replacement of highway signs, the city's highway naming number adjustment work will cost 200 million yuan.
Han Han published the blog post "G8 Highway" and said, "A piece of iron is 40,000 pieces, is it familiar? Yes, the price of the piece on your car is the same (Note: Shanghai's car license is auctioned, tens of thousands Yuan). This shows that for many years, the car owners in Shanghai actually smashed the Shanghai government. Do you think this is extortion? No, these 40,000 are actually the cost of raw materials. Otherwise, how can they get their own iron? How much money do you have?"
A friend of the website of the Shanghai branch of the Aika website said, "A piece of iron brand, spray paint to 40,000. Package for me, as long as 20,000." This caused a wave of netizens bidding, "The landlord is too dark, I am 10,000 I can't smile." "Give me 8000, you 2000 rebate", "6000 pieces of warranty for life"... Shanghai Expressway road sign used to be A-head, now it has become G-head, there are netizens who may slap G It refers to GOLD (gold), so the value is 40,000.
Supplier price is 1000 yuan per square meter
According to reports, Guangdong Foshan "is expected to involve about two or three thousand road signs, about 5 million yuan or more," and it is far less than 40,000 yuan.
Several suppliers in Zhejiang and Shanghai also responded that the highest quality road sign on the expressway cost between 850 yuan and 1,000 yuan. Judging from the news map, the replacement of the road sign area in Shanghai is about 2 to 5 square meters.
Management Office: In fact, there are more than 5,000 street signs
According to relevant sources of the Shanghai Highway Administration Office, the statement that “the cost of each street sign is 40,000 yuan†in Han Han’s blog is wrong. The replacement of the road sign is a large and complicated system project. The 5000 road signs mentioned in the Han Han blog only refer to the urban expressway and ground road road signs connected to the expressway in Shanghai, which only account for the replacement of the road sign. A small part, in fact, the entire highway needs to be replaced more than this number.
