Is there a speed camera in Long Qing Expressway?

Yes Jinan to Qingdao * * *, fixed snapshot points 12, one in Qingdao and two in Weifang. Qingdao toll station is 33 kilometers west, which is the only fixed speed measuring point in Qingdao section. I saw an iron shelf above the middle of the road with two round glass mirrors on it. Speed photography and illegal photography are automatic photography, and speed photography adopts interval speed measurement. Working principle: Calculate whether the vehicle is speeding according to the "average speed" and adopt the two-point snapshot mode.
