Speed Detection of moving vehicle using speed cameras

چکیده
How is the Vehicle's Speed Detected by the Radar? Radar makes use of electromagnetic waves to detect objects and give info (speed, distance, etc) about them. It makes use of Doppler Effect to determine the vehicle's speed. They calculate and scale the variation of frequency between the received and sent radio waves (echo). The frequency will be lower if the object is moving away and is higher if it is moving closer. So, based on the level of echo, it is possible to decide the speed of the moving object.

متن کاملDo speed cameras reduce speeding in urban areas?
This observational study aimed to estimate the prevalence of speeding on urban roadways and to analyze associated factors. The sample consisted of 8,565 vehicles circulating in areas with and without fixed speed cameras in operation. We found that 40% of vehicles 200 meters after the fixed cameras and 33.6% of vehicles observed on roadways without speed cameras were moving over the speed limit ...
متن کاملMoving Vehicle Detection Using a Single Set of Quickbird Imagery — an Initial Study
Moving vehicle detection has become increasingly important in transportation management and road infrastructure development. State-of-the-art moving vehicle detection techniques require multi-frame images or at least a stereo pair of aerial photos for moving information extraction. This paper presents a new technique to detect moving vehicles using just one single set of QuickBird imagery, inst...
متن کاملAn algorithm to estimate mean traffic speed using uncalibrated cameras
In this paper, we present a novel approach to estimate traffic speed using a sequence of images from an uncalibrated camera. We assert that exact calibration is not necessary to estimate speed. Instead, we use 1) geometric relationships inherently available in the image, 2) some common-sense assumptions that reduce the problem to a one-dimensional (1-D) geometry, 3) frame differencing to isolat...
