An operator records the moment that a vehicle passes two fixed objects such as a white circle or square painted on the carriageway that are a known distance apart. The vehicle s speed is then calculated by dividing the distance by the time. This technique can also be used to determine a vehicle s speed from helicopters and other aerial platforms, making it easier to secure a conviction.

Methods Mobile Gatso speed camera Image mobile speed camera.jpg thumb right Gatso Mobile Speed Camera, used in Victoria. This mobile camera or speed camera is used in Victoria and Queensland, and can be operated in various manners. Without a flash, the only evidence of speed camera on the outside of the car is a black rectangular box, which sends out the radar beam, about 30cm by 10cm, mounted on the front of the car. On the older models of the camera, and on rainy days or in bad light, a cable is used to link it to a box with a flash placed just in front of the vehicle. The operator sits in the car and takes the pictures, which are then uploaded to a laptop computer. In both states unmarked cars are used, although in Victoria the operation of the cameras is carried out by a contractor from Serco, in Queensland a uniformed police officer is the operator. Many of the modern Gatso cameras now feature full capability, flashless operation. The advent of infra red flash technology has provided Gatsos with the capacity to capture vehicles exceeding the limit in varying conditions without emitting a bright flash, wh ... more details

Most radar detectors are used so the driver can reduce the car s speed before being Speeding ticket ticketed for speeding . Only doppler radar based devices can be detected other speed measuring devices including those using Automatic number plate recognition ANPR , piezoelectricity piezo sensors, and VASCAR technology cannot be detected. LIDAR devices require a different type of sensor, although many modern detectors include LIDAR sensors. Most of today s radar detectors detect signals across a variety of wavelength bands usually X band X , K band K , and Ka band K sub a sub . In Europe the Ku band K sub u sub band is common as well. Description One of the technologies that law enforcement agencies can use to measure the speed of a moving vehicle uses doppler radar to beam a radio wave at the vehicle, and then infer the vehicle s speed by measuring the Doppler effect moderated change in the reflected wave s frequency. Radar gun s can be hand held, vehicle mounted or mounted on a fixed object, such as a traffic signal . Radar detectors use a superheterodyne receiver to detect these electromagnetic emissions from the radar gun, and raise an alarm to notify the motorist when a transmission is detected. False alarms can occur however due to the large number of devices, such as automatic door openers such as the ones at supermarkets , that operate in the same part of the electromagnetic spectrum as radar guns. In recent years some radar detectors have added GPS technology. This allows users to manually store the locations where police frequently monitor traffic, with the detector sounding an alarm when approaching that location in ... more details
