Due to the increasing number of vehicles on the road, traffic management has become very important. Traffic issues are becoming more complicated as time passes by. It's hard to monitor 24/7 the whole roadways because of limited resources. By using drones in traffic management, it can monitor roads day and night.
They can be used also as traffic surveillance camera. Since traditional tech for traffic surveillance is in a fixed location, we cannot guarantee that they are efficient. With the use of drones, it can provide useful information over space.
i do believe deep aero want a new tecnology in a better way.
but i just want to correct you @LeeMiinHoo!
CCTV are in fixed area but they are making sure that there will be no blind area which they make sure that everything can be seen.
they also have 24/7 operation which drones can't do.
how can a drone monitor the road day and night if its power can only last less than one hour?
