• Abstract:
  The use and creation of combined high-occupancy vehicle/high-occupancy toll (HOV/HOT Lanes) have become ; more common in urban areas since all types of road users can take advantage of the lane either as a highoccupancy ; vehicle or opting in to pay a congestion adjusted free. However, to maintain working integrity of the ; lanes for all users, stepped enforcement to discourage cheating has been needed as more lanes are added. This ; study evaluated the capability of a novel image sensor device to automate detection of in-vehicle occupants to ; flag law enforcement of HOV/HOT lane violators. The sensor device synchronously captures three co-registered ; images, one in the visible spectrum and two others in the infrared bands. The key idea is that the infrared bands ; can enhance correct occupancy detection through known phenomenological spectral properties of objects and ; humans residing inside the vehicle. Several experiments were conducted to determine this capability across ; varied conditions and scenarios to assess detection segmentation algorithms of vehicle passengers and drivers. ; Although occupancy detection through vehicle glass could be achieved in many cases, improvements must be ; made to such a detection system to increase robustness and reliability as a law enforcement tool. These ; improvements were guided by the experimental results, as well as suggested methods for deployment if this or ; similar technologies were to be deployed in the future.
