Active Sensing Technology

Active sensing systems have been at the core of most infrastructure-based intelligent transportation systems for a number of years, however active sensing is also coming to the next generation of "smart" vehicles.


Report: Trends in Roadway Domain Active Sensing

Developments in Radar, LIDAR and other Sensing Technologies and Impact on Vehicle Crash Avoidance/Automation and Active Traffic Management 


The report analyzes the merits and limits of active sensing technologies (Radar, LIDAR and Ultrasonic detectors)  and how the demands for such technologies is evolving.  Of all the roadway domain active sensing technologies, vehicular radar is the best at detecting typical driving conflicts representing the most common crash risks and thus likely will serve as a key component of collision avoidance systems in many next generation smart vehicles. The report examines how future Vehicle-to-Vehicle communications and Active Traffic Management techniques will improve and complement active sensing in vehicle crash avoidance and driving automation.
