Highway Intersection Sight Distance Guidelines & Measurements
Journal of the National Academy of Forensic Engineers, 1999 Many Highway Accidents Occur At Intersections That Are Not Controlled By Traffic Signals. Intersecting Roadways, Driveways, And Entrances To Shopping Malls Are Only A Few Examples Of Where Crashes Occur. In Some Cases Tort Lawsuits Are Brought Against The Highway Agency Claiming That There Was A Lack Of Sight Distance At The Intersection. Unfortunately,

Design Guidelines For Turbo Roundabout Based on Intersection Sight Distance to Circulating Conflicting Vehicle [PDF]
, 2021 Turbo Roundabout is a roundabout provided with spiral circulatory roadways for effectively counteracting the problems of modern multilane roundabout. This roundabout has an edge over modern roundabouts regarding capacity and safety and was first developed by Professor Fortujin in 1996.Turbo roundabouts are present in large percentage in Europe and is ...

Accounting for animal movement during aerial imaging surveys
Remote Sensing in Ecology and Conservation, EarlyView.Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

Directive Antenna Clutter Loss in Slant Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...
