From the display board, drivers can clearly see the traffic condition of the ways ahead and choose one of the three channels to go to Pudong – the tunnel, the Nanpu Bridge and the Lupu Bridge. The green lines mean normal traffic. Sometimes, it is red, meaning the traffic is high on that road. It also gives drivers estimation to the Bund.
I think this is very cool.
