A method of detecting and counting road vehicles using an acoustic sensor placed by the
road is presented. The sensor measures sound intensity in two directions: parallel and …

Here, we introduce Traffic Ear, an acoustic sensor pack that determines the engine noise of
each passing vehicle without interrupting traffic flow. The device consists of an array of …

The calibration of sound intensity instruments—in particular, with respect to instruments'
sensitivity to both sound intensity and particle velocity in the rated frequency range—is …

The effectiveness of intelligent transportation systems (ITS) strongly relies on the quality of
input data provided by traffic monitoring sensors. Conventional traffic sensors such as …

Safety is one of the key points that limit the spread of light mobility. The objective of this work
is the proposal of a proof of concept of an embedded, low-cost, battery-powered system to …

In this study, we present a machine-learning-based acoustic traffic monitoring aiming to
realize a relatively low-cost system compared with existing traffic sensors. Since vehicles are …

Vehicle speed estimation using acoustic data offers a cost-effective and nonintrusive
approach to enhance traffic safety and efficiency. Previous studies are limited by controlled …

In this study, we present a data augmentation method for machine-learning-based acoustic
traffic monitoring that estimates traffic speed from the running-vehicle sound observed by …

This study describes the development of a passive acoustic speed detecting system,
designed specifically for motorcycles, in order to address the demand for more precise …
