Abstract
This report presents the final results from the MOVE project financed by the BIA program.
The project is a joint project with Acoustic One, Norsk Elektro Optikk AS (NEO), Norsonic, Vegdirektoratet (The Norwegian Public Roads Administration) and NTNU.
In this project, methods and systems to measure the environmental impact of individual vehicles in traffic has been investigated. The main objective has been to monitor the noise levels of passing vehicles in a traffic stream.
In order to monitor the speed and to categorize the vehicle, a radar system TOPO.bigbox from RTB GmbH, Germany has been used. In addition to the use of conventional microphone systems, a microphone array has been tested. An algorithm to acoustically separate the vehicles in a traffic flow has been developed and tested.
Initial tests of the system showed that it is feasible to identify vehicles in the traffic with abnormal noise levels (more than 100 dB(A)) even at moderate speeds.
A new gas detection device, LaserGas iQ2, developed by NEO has also been tested, which showed its ability to detect high CO levels of passing vehicles.
