发明名称 DEVICE AND METHOD FOR TRAFFIC SURVEILLANCE
摘要 <p>A vehicle detector (10) comprises a vehicle sensor (14) arranged for sensing disturbances caused by a vehicle, a digitizer of a microprocessor (20) connected to the vehicle sensor (14). The vehicle detector (10) further comprises a memory (18) connected to the digitizer and arranged for storing the digital representation, an antenna (12) and a transmitter of a radio unit (40). The microprocessor (20) also comprises a controller arranged for controlling operation of the vehicle sensor (14), and the transmitter. The vehicle detector has a housing (49) enclosing the vehicle sensor (14), the digitizer, the memory, the transmitter and the controller. The housing (49) provides protection against mechanical damage and moisture, thereby enabling the housing to be placed under ground. The antenna (12) is provided outside the housing (49) and at a distance from the housing (49) for enabling placement of the antenna (12) within a roadway surface coating.</p>
