Abstract
Sensor nodes are disclosed that act like inductive loops to detect the presence and/or movement of vehicles on at least one roadway. Processors are disclosed using at least one sensor node to communicate vehicle detection that is statistically compatible with the inductive loop response to the vehicles. Installation may configure at least one of the sensor nodes to implement the inductive loop compatibility. Sensor clusters of sensor nodes installed in a roadway may act as inductive loops. Computer readable memories, installation devices and/or servers may deliver a program system and/or a Finite State Machine (FSM) configuration to implement the compatibility and/or an installation package to install the program system and/or the FSM configuration.
