Development and implementation of the areawide Dynamic ROad traffic NoisE (DRONE) simulator

Edward Chung, Ashish Bhaskar

This paper discusses the areawide Dynamic ROad traffic NoisE (DRONE) simulator, and its implementation as a tool for noise abatement policy evaluation. DRONE involves integrating a road traffic noise estimation model with a traffic simulator to estimate ro ...

Large area noise evaluation

Edward Chung, Ashish Bhaskar

A software tool (DRONE) has been developed to evaluate road traffic noise in a large area with the consideration of network dynamic traffic flow and the buildings. For more precise estimation of noise in urban network where vehicles are mainly in stop and ...

Head Mounted Wind

Daniel Thalmann, Frédéric Vexo, Sylvain Cardin

Within the context of tele-presence and immersion for piloting light aircraft, knowledge about the surrounding wind offers useful information for piloting purposes. Rendering wind in virtual simulation or tele-presence application has been used still the e ...

Multicriteria assessment of natural ventilation potential

Claude-Alain Roulet, Mario Germano

A method is proposed to assess the natural ventilation potential by taking into account the most comprehensive set of factors involved in natural ventilation. These factors are either driving forces, such as wind pressure and stack effect, or constraints, ...

Study of vehicle noise for different operating conditions

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

The noise emission level from a vehicle is significantly influenced by different driving conditions and drivers’ behaviour. Almost all the in practice road traffic noise estimation models do not differentiate between different operating conditions. In this ...

Evaluation of Traffic Management Measures on Road Traffic Noise

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

Road traffic noise affects the quality of life in the areas adjoining the road. The effect of traffic noise on people is wide ranging and may include sleep disturbance and negative impact on work efficiency. To address the problem of traffic noise, it is n ...

Acoustic tomography for estimating temperature and wind flow

Martin Vetterli, Luciano Sbaiz, Ivana Jovanovic

We consider the problem of reconstructing superimposed temperature and wind flow fields from acoustic measurements. A new technique based solely on acoustic wave propagation is presented. In contrast to the usual straight ray assumption, a bent ray model i ...

Audiovisual Gestalts

Pierre Vandergheynst, Gianluca Monaci

This paper presents an algorithm to correlate audio and visual data generated by the same physical phenomenon. According to psychophysical experiments, temporal synchrony strongly contributes to integrate cross-modal information in humans. Thus, we define ...

DRONE - a tool for urban traffic noise abatement policy evaluation

Edward Chung, Ashish Bhaskar

Areawide Dynamic ROad traffic NoisE simulator-DRONE, been has developed by the integration of a road traffic noise prediction model (ASJ MODEL-1998) with road traffic simulator (AVENUE) which is further linked with GIS to provide areawide dynamic road traf ...
