An inductive loop detector 10 for use in a vehicle control system provides a control facility for controlling the operation of traffic lights and for controlling the operation of booms and barriers associated with access control. In order to accommodate different operating parameters associated with different applications of the loop detector, the loop detector has a non-volatile memory 18 that can communicate with a portable communicating module for down-loading required operating parameters for the loop detector to a microprocessor 16 of the loop detector, the microprocessor serving to control the operating functions of the loop detector. |
