Implementation of this solution (On-board Unit App) would enable communication between the traffic controllers installed at each crossing and special on-board devices that will be installed or carried in the emergency vehicles. This will allow the emergency vehicles to automatically control the traffic lights through road side units installed at each crossing with traffic controllers and ensure they get the right to passage throughout. Once the vehicle passes the intersection, the traffic control systemwould revert back to its normal function.
Road Side Unit (RSU) Perform one more function to get the health signal of the traffic controller &send it on central server for further analysis to keep track on controller malfunctioning.
App sends command which includes the approaching direction & other information to the RSU via cloud server to get the Green corridor for the same direction.
