Roadside Acoustic Signals Based Road Traffic Density Estimation

2018 Fourth International Conference on Computing Communication Control and Automation (ICCUBEA), 2018
The problem of audio signals based road traffic density estimation is consider in this paper. The vehicles produces various noises(sounds), depending on it's speed, load, and it's mechanical condition, the noise produces such as tire noise, engine noise, engine-idling noise, air-turbulence noise and occasional honks.

Typical West Java Road Surface Power Spectral Density

SAE Technical Paper Series, 1983
<div class="htmlview paragraph">One of the factor which determine vehicle ride quality is the waviness of the road surface. A series of power spectral density measurements has been done on several road types in West Java, that is Macadam, Nacas, Coldmix Buton Asphalt and Hotmix Buton Asphalt.

Bone mineral density of competitive male mountain and road cyclists

Bone, 2002
The purpose of this study was to compare the bone mineral density (BMD) of two types of trained male cyclists (n = 30) with recreationally active men (n = 15), aged 20-40 years. Sixteen of the cyclists regularly trained for, and competed in, cross-country mountain bike races. The other 14 cyclists trained and raced on the road. The cyclists had trained

Histogram-based density discovery in establishing road connectivity

2009 IEEE Vehicular Networking Conference (VNC), 2009
The paper proposes the histogram-based density discovery scheme as an alternative complement in obtaining density to LOUVRE, a landmark-based routing in the vehicular urban environment. The histogram-based scheme does not have the scalability problem as the P2P density scheme.

Power spectral density approximations of longitudinal road profiles

International Journal of Vehicle Design, 2006
The power spectral density (PSD) representation of road profiles can be used both to assess the road roughness, and as an input to vehicle dynamics. The PSD is often approximated with a simple function, using only a few parameters. The present paper presents a literature survey of such PSD approximations, and tests four approximations on longitudinal ...

Road Density Models Describing Habitat Effectiveness for Elk

Journal of Forestry, 1983
Abstract Models depicting elk response to changes in the density of forest roads usually require extrapolation beyond the data. Results are likely to reflect the calculation technique rather than elk behavior. One technique described here does produce a model that coincides with actual elk behavior.
