Claim Text:
1. A loop detection apparatus comprising: an inductive loop; a processing device comprising circuitry configured to connect to the inductive loop and sense from the inductive loop a change in inductance of the inductive loop; and wherein the inductive loop is configured to be disposed at least partially above a surface on which a vehicle travels, wherein the processing device is configured to detect a change in inductance of the inductive loop beyond a first threshold value, wherein in response to detecting the change in inductance of the inductive loop beyond the first threshold value, the processing device is configured to transmit a first signal configured to effect a first action, wherein the processing device is configured to detect a change in inductance of the inductive loop beyond a second threshold value, wherein in response to detecting the change in inductance of the inductive loop beyond the second threshold value, the processing device is configured to transmit a second signal to effect a second action different from the first action.
