ROADWAY SENSING SYSTEMS

摘要

A number of roadway sensing systems are described herein. An example of such is an apparatus to detect and/or track objects at a roadway with a plurality of sensors. The plurality of sensors can include a first sensor that is a radar sensor having a first field of view that is positionable at the roadway and a second sensor that is a machine vision sensor having a second field of view that is positionable at the roadway, where the first and second fields of view at least partially overlap in a common field of view over a portion of the roadway. The example system includes a controller configured to combine sensor data streams for at least a portion of the common field of view from the first and second sensors to detect and/or track the objects.

1. An apparatus to detect or track objects in a roadway area, comprising:
a sensor that is installed at a stationary position in association with a roadway; and a controller configured to direct automated processing of a data stream for at least a portion of a field of view from the sensor to:
define roadway geometry and associated characteristics, the characteristics including traffic flow and trajectories, sensed during a known time period; anddetect a change in sensed traffic patterns, including traffic density and speed, and sensed events, including non-typical vehicular movement and vehicular collision, based on a comparison to the defined roadway geometry and associated characteristics.
