Research Of Call-Center Operation Indices On The Bases Of Queueing Theory And Simulation Models

Abstract

The increase of road traffic in the European Union focuses for creating intelligent transportation systems of traffic control in local, urban and regional level. The possibility of using acoustic sensors for traffic intensity measurements are discussed in this article. Acoustic signal detector, such as an ordinary household microphone, is used as the most inexpensive sensor version for stationary and mobile traffic surveillance systems. The acoustic signals records from different types of road vehicles in various weather conditions examples are described here. The simplified modification of acoustic microphone’s signals spectral processing algorithm and noise filtering are solved. Detection of moving road vehicles results, using records for their acoustic signals, is also discussed here. The restrictions of using acoustic sensors to estimate traffic parameters are established.
