A two-person traffic control unit: They operate stationary lidar device trained on traffic travelling southbound on West Meadow Road, towards Dr. Ann Wang Middle School. Speed limit is 30mph and drops to 20mph at the school zone (ONLY WHEN THE LEGEND ON THE CHANGEABLE 20MPH SIGN IS FLASHING). The apprehending half of the unit, who also operates the stationary lidar, hides behind a unmarked common vehicle, parked on the left side of the school zone crosswalk facing southbound traffic on West Meadow Road. The unmarked common vehicle also serves to hide a marked cruiser parked on Laplume Road, facing northbound traffic on West Meadow Road. Traffic control unit’s location is also concealed by the sharp curves on West Meadow Road, about 700ft from the unit’s position. The apprehending half of the two-person unit physically flags down operators clocked on lidar by stepping in the middle of the school zone crosswalk. The other half of the two-person unit sits in his hidden cruiser and writes citations. The hidden cruiser may also have on-board radar trained on traffic travelling Northbound on West Meadow Road.
