摘要： A traffic monitoring system has a common housing for a Doppler radar transceiver, a video camera, and a digital computer for processing the Doppler signal. The system also includes a video cassette recorder, a high-speed photographic camera, and a laptop computer for downloading control settings and a program from a diskette or memory card to the digital computer. The digital computer performs an initial self-test by injecting a calibration signal in lieu of a Doppler signal into an electronic interface between the radar transceiver and the digital computer. The radar transceiver generates a Doppler signal having two channels, and the phase between the channels indicates whether a vehicle is approaching or receding from the radar transceiver. The two channels are recorded on the left and right audio channels of the video cassette. Recorded with the video signal is a push-down stack of speeds of vehicles detected on the system, in order to present a record of prevailing traffic conditions when prosecuting a speed violator. The recorded picture may also include a series of successive speed measurements for each vehicle. Although an operator could listen to the Doppler signal, it is preferred that the digital computer activates an audio annunciator to emit a click sound when the system detects a vehicle, and a warbly sound when a detected vehicle exceeds a specified speed limit.

摘要： A device for measuring the velocity of vehicles for traffic monitoring a doppler signal transmitter and receiver is used which comprises two mixer diodes arranged to deliver two doppler signals which are dephased against each other by 90.degree., the one or the other signal leading the other, depending on whether the picked up vehicle approaches or recedes from the doppler signal transmitter is fed into a frequency measuring device for measuring the signal frequency as a quantitative measure for the relative velocity between vehicle and doppler signal transmitter. For this purpose one signal of the doppler signal transmitter and receiver 10 is fed into a phase control circuit 34, the output frequency of which is converted into a voltage proportional to the relative velocity between doppler signal transmitter 10 and monitored vehicle. Furthermore, the two signals of the doppler signal transmitter and receiver are fed into a phase detector 26. The output signals of the phase detector circuit 26 are fed into a directional logic circuit 28 which has two logic outputs 30, 32 at which logic signals appear indicating as to whether the picked up vehicle approaches or recedes. The logic signals from the directional logic circuit 28 are fed into a frequency voltage converter 56. The frequency voltage converter 56 has two outputs 62, 64. A voltage proportional to the relative velocity of the picked up vehicle appears at output 62 when the picked up vehicle approaches. A voltage proportional the the relative velocity of the picked up vehicle appears at output 64 when the picked up vehicle deviates.

摘要： Traffic monitoring equipment including traffic speed measuring equipment has a signal validation facility incorporated to enhance reliability of the equipment. This facility permits the monitoring operation, for example speed measurement, to proceed only if the validation is positive, if negative the operation is aborted and/or a warning signal or shutdown is activated. Validation is made of pulse sequence, pulse strength, radio frequency interference, insulation breakdown, cable integrity (where cables are used) and the like.

摘要： Sensors are positioned adjacent a roadway. Such sensors conveniently comprise pressure switches connected to two speed hoses to be run over as in a traffic counter. Alternately, photo-optical, acoustical, or magnetic field sensors can be used. The sensors are spaced a predetermined distance apart in the direction of travel, and provide information to a logic system to measure the speed of vehicles traveling along the roadway. The logic system is connected to a simple readout sign displayed for observation by drivers of vehicles along such roadway, which sign indicates whether a vehicle is traveling at a proper rate, or too fast or too slow, or too close to a preceding vehicle. A modified motion picture camera is provided adjacent the roadway to film a vehicle that is moving too rapidly, and a modified film editing device is provided for counting the frames exposed, and thereby to determine the speed of such vehicle. This latter device preferably reads out direct in miles per hour.

摘要： A traffic monitoring apparatus includes a camera and a photoflash unit to automatically take a picture of a vehicle illegally entering an intersection against a stop light. The camera simultaneously takes a picture of a time display device. One of the times indicated on that device is derived from an electronic digital counter. To ameliorate the problem of false counts in the counter caused by the opening of the switch which initiates the photoflash, a Zener diode and a capacitor are connected in parallel with that switch.

摘要： A traffic-monitoring camera is removably mounted on a housing with its primary lens extending horizontally above the housing. Within the housing are instruments, e.g., clock, to be simultaneously photographed. The housing has a fixed holder to which a lens mount is adjustably affixed and positioned in the housing. An auxiliary wide-angle lens is secured in the mount and positioned with its optical axis horizontally and symmetrically between the instruments. Mirrors and a tube provide a path for the light rays from the auxiliary lens to the camera field.

摘要： A doppler radar vehicle speed measurement template is provided with a representation of the photograph zone intersecting with a horizontal line representing the horizon of the road and a vertical line representing the vertical plane of the optical axis of the camera. The template is laid over the photograph with the vertical and horizontal lines aligned with the center of the photograph and with either the vanishing point of the road or a point at the height of the camera to accurately locate the vehicle in the photograph zone.
