Wireless vehicle detection uses sensors, typically magnetometers or radar, to detect the presence of vehicles without the need for traditional, wired inductive loopsThese sensors transmit vehicle detection information wirelessly to a control system, like a traffic signal controller or a gate opener. This method eliminates the need for costly and disruptive excavation and cabling. 

How it works:
  • Magnetometers:

    These sensors detect changes in the Earth’s magnetic field caused by the presence of a metal vehicle. 

  • Radar:

    Radar sensors use radio waves to detect the presence of objects, including vehicles. 

  • Wireless Communication:

    The sensor transmits the detection signal wirelessly to a transceiver or controller, which then activates a system, such as a gate or traffic signal. 

Benefits:
  • Reduced Installation Costs: Eliminates the need for ducting and trenching associated with traditional inductive loops. 
  • Faster Installation: Can be installed in hours rather than days, reducing traffic disruption. 
  • Improved Safety: Reduces the risk to road workers and minimizes disruption to residents. 
  • Reliability: Some systems use two-way radio communication for reliable operation. 
  • Versatility: Can be used in various applications, including traffic control, parking management, and gate access control.
