Abstract
A method and system for synchronization of detection loops in a multilane environment. A plurality of loop sensors are arranged in a plurality of lanes such that loop sensors in adjacent lanes are mutually contiguous. A simultaneous synchronization signal is sent to each of the plurality of loop detector controllers, where each loop detector controller is in communication with a loop sensor. The signal causes a scheduling of sampling periods for each loop sensor, such that the sampling period of each loop sensor does not overlap with that of a contiguous loop in an adjacent lane.
