A New Method Has Been Patented To Measure The Flow Of Traffic A Street Has To Bear By Measuring Atmospheric Noise
-Researchers from the University of Granada and the Carlos III University of Madrid have developed a pioneer system, unique in the world, which is more efficient and accurate than any other currently-used method
-The system is able to distinguish between the flow of cars, LGVs, HGVs or motorbikes/scooters traveling along a certain road
Researchers from the University of Granada and the Carlos III University of Madrid have patented a new method to measure the flow of motorized traffic that a specific street carries each day, by measuring solely the levels of atmospheric noise. This pioneer system, unique in the world, is an alternative, or a complement, to other methods currently used to measure traffic flow, such as image counting or magnetic discharge levels.
As the co-author of the research, Diego Pablo Ruiz Padillo, explains to us, this method can be used to control the type of traffic allowed in certain town or city areas (for example, to restrict HGVs on certain roads or streets); to obtain additional information for city/town planning; how to plan the number of parking spaces available for motorbikes/scooters; traffic-light regulation or to study traffic flow and its impact on the inhabitants of the urban area under study.
Ruiz also points out that the University of Granada group´s invention, which has been patented by the Office for Research Results Transfer (OTRI), is, in fact, the processing system; software that, coupled to the noise meters or sound-level meters, allows an estimation of traffic flows, since the information is transmitted wirelessly.
In addition to Prof. Ruiz Padillo, the other researchers that have taken part in this Project have been Dr. Laura Martin and Dr Antonio Torija, from the University of Granada, along with Prof. Joaquin Miguez, from the Carlos III University of Madrid.
