The sound sensors are introduced at level with interims out and about asphalts and these sensors are primarily set up for the purpose crisis vehicles, for example, emergency vehicle. At the point when an emergency vehicle is struck in rush hour gridlock for over 120 seconds, the sensors that are introduced close by the streets will detect the flag from the rescue vehicle siren and sends the data to the ATCS. The ATCS at that point switches the flag shading to blue, which shows the nearness of a rescue vehicle. By doing as such the movement can be cleared rapidly before the emergency vehicle achieves that specific territory.
