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.

Abstract translation: 用于在多环境中同步检测环路的方法和系统。 多个环路传感器布置在多个通道中，使得相邻车道中的环路传感器相互邻接。 同时同步信号被发送到多个环路检测器控制器中的每一个，其中每个环路检测器控制器与环路传感器通信。 信号引起每个环路传感器的采样周期的调度，使得每个环路传感器的采样周期与相邻通道中的连续环路的采样周期不重叠。

Abstract: A ferromagnetic loop having a footprint characterized by a continuous wire shaped in a serpentine manner to form multiple contiguous polygons within the footprint for detection of moving vehicles. The footprint can be one of a triangle, a square, a rectangle, a rhombus, a parallelogram, an ellipse, or a circle. Similarly, each of the multiple contiguous polygons can be one of a triangle, a square, a rectangle, a rhombus, a parallelogram. Different design configurations for the ferromagnetic loop and methods for making and using the same are disclosed.
