This layout is used when speed or class data is needed for each lane on two lanes of traffic going in the same direction. Sometimes referred to as a
short tube-long tube setup, it consists of two 'short' tubes (A & C) that are installed over the first lane and two 'long' tubes (B and D) that are installed
over both lanes.
Vehicles in the inner lane hit all four tubes, but their hits on the B and D tubes are not counted since they were immediately preceded by a hits on the A
and C tubes. Vehicles in the outer lane hit only the B and D tubes.
