Title: Method of installing magnetic sensor loops in a multiple lane highway

Abstract: A method of installing an electromagnetic sensor loop in a multiple lane highway for monitoring vehicle traffic which includes the steps of placing a test loop at a desired location in a highway traffic lane approximately centrally thereof and varying the lateral dimension of the test loop until the field strength generated thereby at the lane edge is such that the loop will reliably distinguish between a vehicle in the lane in question and a vehicle in the next adjacent lane.
