متن کاملSpeed Detection of moving vehicle using speed cameras
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 i...
متن کاملVehicle Reidentification and Travel Time Measurement Using Loop Detector Speed Traps
1 This dissertation presents a vehicle reidentification algorithm for consecutive detector stations on a freeway, whereby a vehicle measurement made at a downstream detector station is matched with the vehicle's corresponding measurement at an upstream station. The algorithm should improve freeway surveillance by measuring the actual vehicle travel times; these are simply the differences in the...
متن کاملAn ANP-based Model for Location of Fixed Speed Cameras
Speeding is a major cause of traffic accidents and is estimated to be the cause of about 40% of fatalities in road accidents. Speed is a major accident risk factor and affects both rate and severity of traffic accidents. This importance has led to universal use of intelligent control systems for maintaining road safety by enforcing speed regulations. In this study, a modeling is carried out by ...
متن کاملDo speed cameras reduce collisions?
We investigated the effects of speed cameras along a 26 mile segment in metropolitan Phoenix, Arizona. Motor vehicle collisions were retrospectively identified according to three time periods - before cameras were placed, while cameras were in place and after cameras were removed. A 14 mile segment in the same area without cameras was used for control purposes. Five cofounding variables were el...
