Acoustical analysis of road traffic density

Abstract

Road traffic is one of the most often used means of transportation of people and goods today. Consumerism causes a constant increase in the demand for goods and services. Our paper presents a proposal for traffic monitoring. Its aim was to design a method for measuring traffic density using acoustical methods. It describes the results of measuring traffic density via acoustical methods and their comparison with actual traffic density obtained from video camera records. Traffic density was measured also for individual vehicle categories. Measurement and analysis of audio and video records has shown a correlation between the actual number of vehicles passing by and data about the number of vehicles obtained from the analysis of audio records.
