摘要
A vehicle sensor pre-fabricated and tested in factory before being installed in a road surface. It consists of electrically inductive coils with known, tried and tested characteristics for the sensing of road traffic vehicles of various categories. When connected to appropriate electronic equipment, the sensor assembly detects the presence of a vehicle, whether moving over the sensor or in a stationary position. Each sensor has shape and dimensions which enable it to be fitted into a single slot cut in a road surface. When used in a carriageway with more than one lane, then the slot is cut across all lanes with a sensor assembly fitted into each lane throughout the slot. The sensor assemblies are pre-formed in a range of dimensions allowing installation in roads and lanes with standard and non-standard widths.
