Abstract
Official abstract text for this publication.
A vehicular observation and detection apparatus and system incorporates a detection framework using video analysis to differentiate between motorized vehicles and bicycles for improved traffic flow and safety at intersections. The detection framework creates virtual zones overlaid on lanes of a roadway and analyzes input data representing objects in the virtual zones collected from one or more cameras positioned at or near the roadway.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of detecting a presence of bicycles in a roadway for traffic signal controller management, comprising: creating a virtual bicycle zone in one or more lanes of a roadway near a traffic intersection; generating, for each virtual bicycle zone, a bicycle detection strip at a specified portion adjacent to each virtual bicycle zone, the bicycle detection strip having a substantially similar shape as the bicycle zone; detecting motion inside the…
