The sound sensors are presented at level with intervals out on the town pavements and these sensors are fundamentally set up for the reason emergency vehicles, for instance, crisis vehicle. Right when a crisis vehicle is struck in surge hour gridlock for more than 120 seconds, the sensors that are presented near to the lanes will recognize the banner from the safeguard vehicle siren and sends the information to the ATCS. The ATCS by then switches the banner shading to blue, which demonstrates the proximity of a save vehicle. By doing all things considered the development can be cleared quickly before the crisis vehicle accomplishes that particular domain.
