Portable, Solar-charged Traffic Signal

In Miami, tropical storms and hurricanes often cause communities to lose electrical power for long periods of time, setting off accidents and causing unsafe roads. The objective of the InvenTeam's device is to maintain traffic flow, thus allowing police officers to concentrate on other pressing issues instead of directing traffic. The device is eight feet long when unfolded, weighs 60 pounds, and operates for three days per the battery's lifespan. BP solar and R4 Systems provided supplies to the InvenTeam.
