"Right, I forgot to emphasize one thing. Audience members, please do not use your phones to take pictures!" Mayor Li said.
"The Sand Table Competition involves some sensitive information, so a certain degree of confidentiality is required. Thank you all!"
Not a single person in the audience even took out their phone. Today's audience had all been led by counselors from various universities, and they had been warned before coming that photography was forbidden. Anyone caught taking a picture by their teacher would receive a serious disciplinary warning in no time!
The students all thought the reason photography was forbidden was the city map on the sand table. Only Song He knew that the real reason was him.
His identity was sensitive. Before any photos could spread online, photography had to be prohibited mainly to protect him. What was there to keep secret about the city's roads? Ridiculous. A quick search on a navigation app would show everything clearly!
"Everyone, please look at the sand table I'm standing in!" Mayor Li introduced. "This is the full-road sand table of Dongcheng District. It's highly intelligent!"
"How is it intelligent? Let me demonstrate!"
"First, the traffic lights!"
Mayor Li pressed the Remote Control, and the traffic lights at every intersection lit up together. Their dazzling lights flashed and changed!
"The countdowns of all the traffic lights have been set according to the real timing of the traffic lights at each intersection, at the same ratio!"
"For example, on Dongjiang Road, the real interval between the light changing from red to green is thirty seconds, and cars traveling through the entire street at the green-wave speed also take exactly thirty seconds! On the sand table, simulated cars only need five seconds to cross the entire street, so the traffic-light timing is shortened proportionally
