Description:
The system concept is using an unmanned aerial vehicle (UAV) and combining wireless
camera to provide real time imaging. The concepts of the operation consists activation,
operation, detection, and imaging. For operation, a remote controller will be used by the
operator.During activation, the system will be turned on after the batteries are fully
charged. The system will be activated by Li-Po batteries which will allow the system to fly
and transmit data to the operator at all times. During operation, Draganflyer will be
controlled by the operator by a remote controller throughout the designated area. The
location of the Draganflyer will be obtained by the operator through a video glass tat will
update the location of the UAV.Once the UAV is up on the air, it will start detecting any
traffic problems. The operator will be able to catch where the problem is and will respond
to current situationOnce the operator detects a problem, he can notify the central traffic
communication center by providing the image of current situation in order to solve the
problem.

C.1 Dragon Flyer
Description:
Draganflyer is a remotely controlled unmanned UAV that is mainly designed to carry wireless
cameras to capture digital images.
The system can serve multiple purposes throughout the industry that needs surveillance and
aerial imaging. The miniature UAV will be operated by a handheld controller while the operator
is available to observe what it through a video glass. The entire system will be electrically
powered and will be charged before use.
Once Draganflyer is in air, the system should be able to detect current situation of traffic in a
designated area and can notify the operator about current situation. This will be notified to
nearby traffic control station to aid traffic situation.
